Introduction: The Importance of Social Responsibility in the Engineering sectorEngineering is a field that plays a critical role in society, with engineers being responsible for developing and implementing innovative solutions that can address complex challenges. However, as the world becomes more connected, it has become increasingly important for engineers to consider the impact of their work on society, the environment, and the economy.
This is where the concept of social responsibility comes in. Social responsibility is the idea that businesses and individuals have an obligation to act in a way that benefits society as a whole, rather than just their own interests.In the engineering sector, social responsibility means that engineers must consider the impact of their work on society, the environment, and the economy. This is particularly important in developing countries like South Africa, where access to basic services and infrastructure is often limited.
The purpose of this report is to examine the importance of social responsibility in the engineering sector, with a focus on South Africa, other African countries, and developed countries. The report will compare and contrast the approaches taken by these countries and highlight the economic significance of social responsibility in engineering entrepreneurship. The report will also examine how COVID-19 has affected the importance of social responsibility in the engineering sector, particularly in terms of the role that engineers have played in addressing the pandemic. The completion of this study will fill a gap in the understanding of the importance of social responsibility in the engineering sector, and provide guidance on how engineers can better integrate social responsibility into their work.

A Moore Machine is a type of finite state machine that has an output depending on the present state alone and not on the input (in other words, no matter what caused the transition from the prior state to the current state).
A sequence detector is a type of Moore machine that receives input and counts how many times a specific input sequence occurs; when it reaches a specific number of occurrences, it generates a single output of "yes." The output is "no" otherwise.The given Moore machine counts the occurrence of the sequence '011' in any input binary strings over input alphabet {0, 1} and output alphabet {a, b}.
Next, we will convert the above Moore machine into its corresponding Mealy machine. The output of the Mealy machine is determined by both the current state and the current input, so the output is assigned to the arrows leading from the state. The figure below shows the Mealy machine derived from the Moore machine: To find the respective output for the input sequence '011011' on the Moore machine, we need to follow the path in the diagram for the given input.

(25%) (C) A single-phase transformer rated at 2500 kVA, 60 kV input/ 3kV output, 60 Hz has a total internal impedance Zp = 100 32, referred to the primary side.

Comment on the regulation. [30%] (iii) The primary and secondary currents if the secondary is accidently short-circuited. Comment on the effect of this on the transformer. [20%)
The active power dissipated in resistor is 0.00001 W and the leakage resistances are also present in the circuit.
(i) For the given transformer, the turns ratio, N, is 1:8. We are given that a 1600 S2 resistor is connected across the secondary of this ideal transformer. So, the resistance seen by the primary will be:
Rp = (Ns/Np)²Rs
Where, Np = Number of turns in the primary, Ns = Number of turns in the secondary, Rs = Resistance connected across the secondary= 1600 Ω
Putting all the values, we get:
Rp = (8/1)² × 1600 Ω= 102400 Ω
(ii) Given that the primary voltage Eg is 2 V. We know that, Eg = VpIp
where,Vp = Primary voltage, Ip = Primary current
We need to find Ip and active power dissipated in the resistor. So,
Ip = Eg / Vp= 2 / 8= 0.25 A (Current in primary)
Voltage across the resistor = Voltage across the secondary = 2 / 8 = 0.25 V (Using voltage division rule)
Active power dissipated in the resistor = (Irms)² x R= (Vrms / R)² x R= (0.25 / 1600)² × 1600= 0.00001 W
The equivalent circuit to represent a practical single-phase transformer is shown below:
Here, Rp and Xp are the resistance and leakage reactance of the primary winding. Similarly, Rs and Xs are the resistance and leakage reactance of the secondary winding. In a practical transformer, the iron core is not perfect due to which the magnetic flux, Φ that links both the primary and secondary winding does not remain entirely confined to the core but also passes through the air. This causes the reluctance of the core to increase, leading to an increase in the flux leakage.
Therefore, the leakage reactances Xp and Xs are also present in the equivalent circuit.
The above is the equivalent circuit of a practical single-phase transformer that represents an imperfect core, primary leakage reactance, and secondary leakage reactance. (C)
Therefore, it is essential to protect the transformer from accidental short-circuit by providing fuses, circuit breakers, or overload relays.

A circular disc of charge of radius Im having a uniform charge density ps = +InC/m² lies in the z = 0 plane, with center at the origin. There is also a point charge of -4 nC at the origin. Find the magnitude and polarity of uniform charge density of a circular ring of charge of radius Im lying in the z = 0 plane, with center at the origin, which would produce the same electric field intensity at the point (0,0,6)m as that due to the combined effect of the disc and point charges. Medium is air. {COI} 8
Given that,
Radius of the circular disc of charge, R = l m
Uniform charge density of the circular disc of charge,
ρs = +l nC/m²
Charge on point charge, q1 = -4 nC
Position of point charge, r1 = 0
Electric field at the point (0, 0, 6),
E = Ei + Eo
Where,Ei is the electric field due to the ring of charge
Eo is the electric field due to point chargeLet's find the electric field Eo due to point charge using Coulomb's law.
The electric field due to the point charge is given by;
Eo = kq1/r1²
Where k = 9 × 10⁹ Nm²/C² is Coulomb's constant, and r1 = 0 because the point charge is at the origin.
Thus, Eo = ∞
We know that the electric field Ei due to a ring of charge is given by;
Ei = (1/4πε₀) [q/r²] × sin θ
Whereq = charge on the ring of charge
ε₀ = permittivity of air
r = distance between the ring of charge and the point at which electric field is to be determined
θ = angle between the axis of the ring and the line connecting the ring and the point at which the electric field is to be determined.
Here, the ring and the point are in the z = 0 plane, thus r = 6 m.
Let dq be an element of charge on the ring of charge of thickness dr.The total charge on the ring of charge can be expressed as;
q = ρs (2πR)(l)
Where R is the radius of the ring of charge.
Thus,
dq = ρs (2πR)(l)dr
The electric field due to the element of the ring of charge at a point P is given by;
dE = k dq/r²
Now,
sin θ = z/r
= 6/[(x²+y²+6²)]^(1/2)
As z = 0, sin θ = 0
We know that,
dE = k dq/r² and dq = ρs (2πR)(l)dr
So, dE = k ρs (2πR)(l)dr/r²
Electric field at the point P due to the entire ring can be expressed as,
Ei = ∫dE = ∫₀²πkρsRl dr/r²= 2πkρsRl [(1/3R)² - (1/R)²]= (1/3πε₀) [(lRρs/3) - q/R]
The electric field due to the combined effect of the disc and point charges is given by,
E = Ei + Eo
Thus, (1/3πε₀) [(lRρs/3) - q/R] = E
The value of R is given by;
R² = x² + y²
Now, x = 0 and y = R
The electric field E at point (0, 0, 6) can be expressed as;
E = k [(-4 nC)/6²] + (1/3πε₀) [(lRρs/3) - q/R]
Solving for ρs gives;lRρs = 9πE[6² + R²] / 2
Therefore,
ρs = 9πE[6² + R²] / (2lR)
Hence, the magnitude of the uniform charge density of a circular ring of charge of radius R lying in the z = 0 plane, with the center at the origin, which would produce the same electric field intensity at the point (0,0,6)m as that due to the combined effect of the disc and point charges is 9πE[6² + R²] / (2lR).

Assume that the turbine is spinning the generator at 1050 rpm when the connecting switch to the grid is closed. a) Calculate the stator inrush current at starting. b) Calculate the required firing angle to achieve soft starting, whereby the initial inrush current is limited to 20% of the rated current.
The stator inrush current at start is 10.375 A and the firing angle for soft starting is 81.3°.
Given data: Type 1 wind turbine with six poles, 50 Hz three-phase, Y-Connected squirrel cage induction generator. Parameters of machine are r1=r'2= 4 mΩ, x1= x'2= 40 mΩ, Xm=5 .The terminal voltage is 415 V. The turbine is spinning the generator at 1050 rpm when the connecting switch to the grid is closed. Soft starting current is to be limited to 20% of the rated current. At the start, the frequency of the rotor is the same as that of the stator. The rotor will have zero slip. Therefore, the inductive reactance of the rotor is zero. Therefore, the rotor impedance is equal to rotor resistance R'2. At the start, the stator winding is an open circuit. Hence, the induced emf in the stator is zero. Therefore, the current in the stator winding is equal to the inrush current
Inrush current at starting: Stator inrushes current at starting = Vt / X1= 415 / (x1) mΩ= 415 / 40= 10.375 A Therefore, the stator inrush current at the start is 10.375 A.
Firing angle for soft starting: In soft starting, the initial current should be 20% of the rated current. That is, the initial stator current should be 20% of the rated stator current. The rated current of the stator is given byIrated = Vt / ( √3 * Z)where Z is the equivalent impedance of the stator winding and the magnetizing reactance Xm. Z can be calculated as follows: Z = [(R1 + R'2)2 + (X1 + X'2 + Xm)2]1/2
Given that R1 = R'2 = 4 mΩ, X1 = X'2 = 40 mΩ, Xm = 5 mΩ∴ Z = [(4 + 4)2 + (40 + 40 + 5)2]1/2∴ Z = 88.81 mΩIrated = Vt / ( √3 * Z)= 415 / ( √3 * 88.81)= 2.4 A Therefore, the initial stator current should be 20% of 2.4 A, i.e., 0.48 A. Now, the phase voltage of the stator is given by Vp = Vt / √3= 415 / √3The voltage across the thyristor is given by the product of Vp and 1.35 [approx.]VSCR = Vp * 1.35= 415 / √3 * 1.35= 418 VThe rms voltage across the thyristor is given byVrms = VSCR / √2= 418 / √2The firing angle is given bycosα = I / (Vrms / (√2 * Irated))where I is current at the firing angle and Irated is the rated current of the stator. Here, I = 0.48 A cosα = 0.48 / [418 / (√2 * 2.4)]cosα = 0.1434α = cos-1(0.1434). Therefore, the firing angle for soft starting is 81.3°.
Inrush current refers to the momentary current drawn by an electrical device at the time of switching on. In an induction motor, at starting, the rotor frequency is the same as that of the stator. The rotor will have zero slip. Therefore, the inductive reactance of the rotor is zero. Therefore, the rotor impedance is equal to rotor resistance R'2. At the start, the stator winding is an open circuit. Hence, the induced emf in the stator is zero. Therefore, the current in the stator winding is equal to the inrush current. The rated current of the stator is given byIrated = Vt / ( √3 * Z)where Z is the equivalent impedance of the stator winding and the magnetizing reactance Xm. In soft starting, the initial current should be 20% of the rated current. That is, the initial stator current should be 20% of the rated stator current. The voltage across the thyristor is given by the product of the phase voltage of the stator and 1.35 [approx.]. The rms voltage across the thyristor is given by the product of voltage across the thyristor and √2. The firing angle is given bycosα = I / (Vrms / ( √2 * Irated))where I is the current at the firing angle and Irated is the rated current of the stator. Therefore, the firing angle for soft starting is 81.3°.
The stator inrush current at start is 10.375 A and the firing angle for soft starting is 81.3°.

Sampling is a process of selecting a subset of individuals from a large population to estimate parameters such as mean, variance, and standard deviation. It is an essential aspect of statistical analysis and is commonly used in research studies to avoid data collection on the entire population. There are two types of sampling techniques: probability and non-probability sampling. Probability sampling involves random selection of individuals from the population, while non-probability sampling does not.
Random sampling is one of the most commonly used probability sampling techniques. It involves selecting individuals from the population randomly and without bias. In this method, every individual has an equal chance of being selected, and no particular characteristic is given priority. Another type of sampling method is stratified sampling, which involves dividing the population into strata or subgroups based on specific characteristics. Then, individuals are randomly selected from each group to form the sample.
Cluster sampling is another type of probability sampling method that involves dividing the population into clusters or groups based on geographic, demographic, or other relevant factors. The researcher then selects a few clusters randomly and collects data from all individuals within the selected clusters.Non-probability sampling techniques include convenience sampling, purposive sampling, and quota sampling. Convenience sampling is a type of non-probability sampling method that involves selecting individuals who are readily available to participate in the study.
In conclusion, sampling is a crucial aspect of statistical analysis that involves selecting a subset of individuals from a population to estimate parameters. There are different types of sampling techniques that researchers use to obtain a representative sample. Probability sampling techniques involve random selection, while non-probability sampling techniques do not.

An active HIGH input S-R latch is formed by the cross-coupling of two NOR gates.
The S-R latch is one of the fundamental components used in the design of digital circuits. A latch is a circuit that can remember the state of an input signal. The most basic type of latch is the S-R latch. It is formed by the cross-coupling of two NOR gates. The S-R latch has two inputs: the set input (S) and the reset input (R). When the set input is HIGH, the output of the latch goes HIGH. When the reset input is HIGH, the output of the latch goes LOW. When both inputs are LOW, the output of the latch remains in its previous state. When both inputs are HIGH, the output of the latch is undefined. The cross-coupling of two NOR gates produces an S-R latch. Each gate has two inputs and one output. The output of one gate is connected to one of the inputs of the other gate. The other input of the first gate is connected to the output of the second gate. This arrangement forms a feedback loop that allows the circuit to remember its state.

Create rule table for a DfA that determines if a string begins
and ends with 1
A rule table for a DFA that determines if a string begins and ends with 1 can be created by following the above-given steps, and the DFA machine will accept any input string that begins and ends with 1.
To create a rule table for a DFA that determines if a string begins and ends with 1, we need to follow the below-given steps:
Step 1: Constructing DFA machine: The first step in creating a DFA for any regular language is to construct the DFA machine, which involves creating a state diagram and transition table.
Step 2: Determining the number of states: Determine the number of states in the DFA machine. In this case, there are three states, q1, q2, and q3, where q1 is the starting state, and q3 is the final state.
Step 3: Create a transition table: Next, we create a transition table to keep track of the machine's state changes in response to a given input. For this example, the transition table looks like this
Step 4: Implementing the rules: We implement the rules that the machine should follow in response to a given input. In this example, the rules are as follows:
If the input is 0, stay in the current state. If the input is 1, transition to the next state. If the machine is in state q1 and the input is 1, transition to q2.If the machine is in state q2 and the input is 0, transition to q3. If the machine is in state q3 and the input is 1, transition to q3. Otherwise, transition to q1.
Step 5: Testing the DFA. Finally, we test the DFA machine by providing it with various input strings to ensure that it is working correctly. The DFA machine will accept the input string if the final state is reached when all the inputs have been processed. For this example, the DFA machine will accept any input string that begins and ends with 1.
Therefore, a rule table for a DFA that determines if a string begins and ends with 1 can be created by following the above-given steps, and the DFA machine will accept any input string that begins and ends with 1.

For the velocity field V = Ax²y i+ Bxy j where A = 2 m² s¹ and B = 1 m² s¹ and the coordinates are measured in meters, obtain an equation for the flow streamlines. Plot several streamlines in the first quadrant.
We can plot several streamlines in the first quadrant by considering different values of `C` in an open channel.
The equation for the flow streamlines for the given velocity field `V = Ax²y i+ Bxy j` where `A = 2 m² s¹` and `B = 1 m² s¹` and the coordinates are measured in meters can be found by using the continuity equation. Continuity equation states that the mass flow rate through any section of a streamtube is constant. Since, the mass is conserved we can say that the volumetric flow rate also remains constant i.e. Q = Av where A is the cross-sectional area and v is the velocity of fluid. Hence, if we plot the streamlines then they will be such that the fluid passing through them will have the same volumetric flow rate. So, for the given velocity field the continuity equation can be given by:
$$\frac{\partial}{\partial x}(Ax^2y) + \frac{\partial}{\partial y}(Bxy) = 0$$
Expanding the above equation we get:$$2Axy + Bx^2 = C$$where `C` is the constant of integration. We can find the value of `C` from the boundary conditions. Now, to plot several streamlines in the first quadrant we need to consider different values of `C`.Let's consider few values of `C` and find the corresponding streamlines.
Case 1: When `C = 0`$$2Axy + Bx^2 = 0$$$$xy + \frac{B}{2A}x^2 = 0$$
This equation represents a family of parabolas as shown below:
Case 2: When `C = 1`$$2Axy + Bx^2 = 1$$$$y = \frac{1-Bx^2}{2Ax}$$
This equation represents a family of hyperbolas as shown below:
Case 3: When `C = 2`$$2Axy + Bx^2 = 2$$$$y = \frac{2-Bx^2}{2Ax}$$
This equation represents a family of hyperbolas as shown below:
Thus, we can plot several streamlines in the first quadrant by considering different values of `C`.

The Newton’s laws of motion are applied to the statics. The statics refers to the motionless state of an object. There are three Newton's laws of motion and the correct one to be applied to statics is the first law of motion, that states that a body at rest or in motion with a constant speed in a straight line will remain so unless an unbalanced force is applied to it.
The Newton’s first law is also called the law of inertia which explains that when a force is applied on a body, the body will resist the force of the applied object, and the object will remain in a state of rest if it was initially at rest.
In addition, the object will continue to move in a straight line with constant speed if it was initially moving in a straight line with constant speed.
In summary, Newton's first law is used in statics, which is called the law of inertia, as it explains how an object will remain in its motion or rest unless an unbalanced force is applied to it.

Afterward, a structure sigaction is defined to customize the action to be taken when the alarm signal is caught. Here, the sa_handler variable is set to catcher.
The first argument specifies the signal to be caught, the second argument specifies the action to be taken, and the third argument specifies the previous action to be saved.
If setjmp returns non-zero, that means longjmp has executed. If setjmp returns zero, that means we are coming from a direct call to the main function.

x= 52 A piple is carrying water under steady flow condition. At end point 1, the pipe diameter is 1.2 m and velocity is (x+ 30) mm/h, where x is the last two digites of your student ID. At other end called point 2. the pipe diameter is 1.1 m, calculate velocity in m/s at this end. Scan the solution and upload it in VUWS. Do not email to the lecturer.
The velocity of the fluid at point 2 is 0.027 m/s when the diameter of the pipe at point 1 is 1.2 m and the velocity of the fluid at point 1 is 0.0228 m/s, and the diameter of the pipe at point 2 is 1.1 m.
The formula to calculate the velocity of the fluid in the pipeline is given as; Where A1 and A2 are the cross-sectional areas of the pipe at points 1 and 2, respectively. V1 is the velocity of the fluid at point 1, and V2 is the velocity of the fluid at point 2. x=52 So, the value of x is 52. Given the diameter of the pipe at point 1 is 1.2m. The radius, r = 1.2/2 = 0.6 m. The velocity of the fluid at point 1 is V1 = (x + 30) mm/h = (52 + 30) mm/h = 82 mm/h = 0.0228 m/s. Area at point 1, A1 = πr1² = π(0.6)² = 1.13 m². Diameter of the pipe at point 2, d2 = 1.1m. The radius, r2 = 1.1/2 = 0.55m. Now, we can find the cross-sectional area at point 2. A2 = πr2² = π(0.55)² = 0.95 m².Now, we can find the velocity of the fluid at point 2 using the formula: A1 = 1.13 m², A2 = 0.95 m², V1 = 0.0228 m/s, V2 = ? Using the formula for conservation of mass, we get; Q = A1V1 = A2V2Where Q is the flow rate of the fluid in m³/s. We know that the area of the pipe at point 1 is larger than at point 2. Thus, the fluid will move faster at point 2 than at point 1. The velocity of the fluid at point 2 is therefore greater than the velocity at point 1. From the above formula; we can calculate the velocity of the fluid at point 2.V2 = A1V1 / A2 = 1.13 × 0.0228 / 0.95 = 0.027 m/s Hence, the velocity of the fluid at point 2 is 0.027 m/s.
The velocity of the fluid at point 2 is 0.027 m/s when the diameter of the pipe at point 1 is 1.2 m and the velocity of the fluid at point 1 is 0.0228 m/s, and the diameter of the pipe at point 2 is 1.1 m.

To perform a single partitioning operation, we choose the first element as the pivot, i.e., "I". Then we start comparing each of the remaining elements with the pivot. The sequence of random characters is: "IR THU DOAN EQS"
1. I is the pivot element.
2. R comes after I, so we compare the next element, T, which is smaller than I.
3. Next element, H, is also smaller than I and T. Therefore, we swap H with R. The sequence becomes "IH TRU DOAN EQS".
4. O is the next element which is smaller than I, so we swap it with T. The sequence becomes "IHT RU DOAN EQS".
5. N is the next element which is smaller than I, so we swap it with U. The sequence becomes "IHNT RU DOAQ ES".
6. The pivot element I is now placed at the correct position in the array. All the elements smaller than I are to its left and all the larger elements are to its right.
Now, we repeat the process for the subarrays to the left and right of the pivot element.
i) Quick sort is a very efficient algorithm for sorting data. However, there are cases when quicksort can become slow and its performance can be degraded. In such cases, it is recommended to switch to the insertion sort algorithm. This is because insertion sort performs well on small datasets. For example, if the size of the dataset to be sorted is less than a threshold value, say 10, then it is better to switch to insertion sort.
ii) The reason why the switch to insertion sort would boost performance is that insertion sort has a lower overhead than quicksort. Quicksort has to divide the dataset into subarrays recursively and then sort each subarray. This overhead can become significant when the size of the dataset is small. On the other hand, insertion sort directly sorts the dataset without any recursive operations. This makes it faster and more efficient than quicksort on small datasets. Therefore, switching to insertion sort would boost performance by reducing the overhead associated with quicksort.
Therefore, in this way, we can perform a single partitioning operation on the given sequence of random characters and also explain when to switch to the insertion sort and how this switch can boost performance.

Recurrences. Give a Θ(n) expression for T(n) for each of the following recurrences using the stated method. Assume that T(n) is constant for n≤2. (a) Master Theorem: T(n)=T(n/2)+n 2
log 2
(n) (b) Substitution or Tree: T(n)=T(7n/10)+n (c) Any Method: T(n)=2T(n−2)+n 2
. Revised to T(n)=2T(n−2)+c, where c is a constant.
The Θ(n) expression for the given recurrence T(n) using the master theorem(Without having slope) is T(n) = Θ(nlog 2 n).
a) Using the master theorem, the equation can be stated as:
T(n)=T(n/2)+n(log 2 n)where a = 1, b = 2, and f(n) = n(log 2 n)
For this recurrence relation, the value of log b
a = log 2 1 = 0 and f(n) = n(log 2 n) = Θ(n log 2 n).
According to the Master Theorem, T(n) = Θ(nlog 2 n). Hence, the Θ(n) expression for the given recurrence T(n) using the master theorem is
T(n) = Θ(nlog 2 n).
b) Using the tree method, we get:T(n) = T(7n/10) + nT(7n/10) = T((7n/10) * 7/10) + (7n/10) = T((49n/100)) + (7n/10)T(49n/100) = T((49n/100) * 7/10) + (49n/100) = T((343n/1000)) + (49n/100)Thus, the recurrence can be expressed as:T(n) = n + (7n/10) + (49n/100) + .....(until we reach n/2 or less)Using the following formula for geometric progression:1 + x + x² + … + xr-1 = (xr - 1)/(x - 1) Here, the first term is n, the common ratio is 7/10. Thus the formula can be rewritten as:T(n) = n * (1 - (7/10)k)/(1 - (7/10)), where k is such that (7/10)k < n/2 (or less)Taking the limit as n approaches infinity, we get: k = log 10/7 nThus,T(n) = 10n * (1 - (7/10)log 10/7 n)/(3)∴ T(n) = Θ(n)Hence, the Θ(n) expression for the given recurrence T(n) using the tree method is T(n) = Θ(n).c) T(n) = 2T(n - 2) + cHere, we can represent n as n = 2k. Hence the recurrence relation can be rewritten as T(2k) = 2T(2k - 2) + c
We can further represent the term T(2k - 2) as 2T(2k - 4) + c, where 2k - 4 = 2(k - 1).
By repeatedly applying the same technique, we get: T(2k) = 2T(2k - 2) + c = 4T(2k - 4) + 3c = … = 2kT(0) + k c
Replacing n with 2k, we get:T(n) = 2kT(0) + k c= n/2 T(0) + (1/2)cHence, the Θ(n) expression for the given recurrence T(n) using any method is T(n) = Θ(n).

Problem 3 (30 pts) Solve the following differential equation y' = 2xy, y(0)=2 4) Exactly (analytically) 5) Using the Runge-Kutta method 6) Plot both solutions in a single graph (using gnuplot, Excel, or any software of choice). Use h=0.15 and x between 0 and 1.5.
Problem 3 (30 pts)Solve the given differential equation `y'=2xy`, `y(0)=2`:4) The answer to the differential equation is as follows.
It can be solved by separating the variables, i.e.,`y'=2xy => dy/y = 2x dx`
Integrating both sides,`∫ dy/y = ∫ 2x dx``ln y = x² + C``y = e^(x²+C) = e^(x²)e^C`
The general solution of the differential equation is `y = Ce^(x²)`
Here, `y(0)=2`Putting `x=0` and `y=2` in the above equation, `2 = Ce^(0)
`=> `C=2`.
Hence, the solution of the differential equation is `y=2e^(x²)`5) Using the Runge-Kutta method
In the Runge-Kutta method, we find the next value of y by using the present value of x and y. The next value of y is calculated by using the values of slope calculated at different points within the interval.
The formula to find the value of y at `x_(i+1)` from the known value of `y_i` is given by,`y_(i+1)
= y_i + (1/6) k1 + (2/6) k2 + (2/6) k3 + (1/6) k4
`Here,`k1 = h f(x_i, y_i)` `k2
= h f(x_i + h/2, y_i + k1/2)` `k3
= h f(x_i + h/2, y_i + k2/2)` `k4
= h f(x_i + h, y_i + k3)`
We have, `f(x, y) = 2xy`Here, `h=0.15` and `x` ranges from `0` to `1.5`.`y_0 = 2` and `x_0 = 0`
Using the above formula, we get the following values of `y` at different points.`x_0 = 0, y_0 = 2` `x_1 = 0.15, y_1 = 2.0636` `x_2 = 0.30, y_2 = 2.1347` `x_3 = 0.45, y_3 = 2.2149` `x_4 = 0.60, y_4 = 2.3066` `x_5 = 0.75, y_5 = 2.4138` `x_6 = 0.90, y_6 = 2.5411` `x_7 = 1.05, y_7 = 2.6954` `x_8 = 1.20, y_8 = 2.8876` `x_9 = 1.35, y_9 = 3.1359` `x_10 = 1.50, y_10 = 3.4792`
Hence, the solution of the differential equation by the Runge-Kutta method is as follows.
