The correct classifications for the given equations are:

1. Separable

2. Separable

3. Neither separable nor linear.

To determine whether each first-order differential equation is separable, linear, both, or neither, we need to analyze the form and properties of the equations. The given equations are:

1. dy/dx = y + e*sin(a)

2. dy/dx = y * ln(r^2 * y)

3. dy/dx = (1/x^2) * e^(3y) - x^2 * y^2 * dy/da

1. The equation dy/dx = y + e*sin(a) is separable because we can rewrite it as dy/(y + e*sin(a)) = dx. By separating the variables, we can integrate both sides with respect to their respective variables.

2. The equation dy/dx = y * ln(r^2 * y) is separable because we can rewrite it as (1/y) dy = ln(r^2 * y) dx. By separating the variables, we can integrate both sides with respect to their respective variables.

3. The equation dy/dx = (1/x^2) * e^(3y) - x^2 * y^2 * dy/da is neither separable nor linear. It involves both the derivative of y with respect to x and the derivative of y with respect to a, making it a partial derivative equation. This equation cannot be separated into variables or expressed in a linear form.

Therefore, the correct classifications for the given equations are:

1. Separable

2. Separable

3. Neither separable nor linear.

To find the derivative of g(x), which is the inverse of f(x) = m3√ em 4 ✓ em 5 ✓ em 6... em 7 ✔ em 8 ✔ em 9 ✓ lem 10 ✓ lem 11 ✓ lem 12 ✓ blem 13 ✓ with g'(x) = X x-1,

you can use the formula: g'(x) = 1/f'(g(x))Let h(x) = m3√ em 4 ✓ em 5 ✓ em 6... em 7 ✔ em 8 ✔ em 9 ✓ lem 10 ✓ lem 11 ✓ lem 12 ✓ blem 13 ✓.

Then, f(h(x)) = x

Solving for h(x), you get: h(x) = f^(-1)(x)

Differentiating both sides with respect to x, you get:h'(x) = [f^(-1)(x)]'

Differentiating the right-hand side with the chain rule gives:h'(x) = 1/f'(h(x))

Differentiating f(h(x)) = x implicitly gives:f'(h(x))h'(x) = 1

Solving for h'(x), you get:h'(x) = 1/f'(h(x))

Therefore, since g(x) = h^(-1)(x),

you have that:g'(x) = 1/h'(g(x))

So, substituting g(x) into the expression for h'(x), you get:g'(x) = 1/f'(h(g(x)))

Finally, since f(h(g(x))) = x,

you can substitute h(g(x)) into the expression for f' to get:g'(x) = 1/[f'(h(g(x)))] = 1/[f'(h(f(h(g(x)))))],

where the second equality follows from the fact that h(f(y)) = y.

Therefore,g'(x) = 1/f'(m3√ em 4 ✓ em 5 ✓ em 6... em 7 ✔ em 8 ✔ em 9 ✓ lem 10 ✓ lem 11 ✓ lem 12 ✓ blem 13 ✓).

Answer:

BD = 34

Step-by-step explanation:

a segment joining the midpoints of two sides of a triangle ( midsegment) is half the length of the third side.

then

BD = [tex]\frac{1}{2}[/tex] AE = [tex]\frac{1}{2}[/tex] × 68 = 34

a) There are 40,320 ways the letters in the word "COMPUTER" can be arranged in a row without any restrictions. b) There are 1,440 ways the letters in the word "COMPUTER" can be arranged if the letters "CO" must remain next to each other (in order) as a unit. c) The probability that the letters "CO" remain next to each other (in order) as a unit when the letters of the word "COMPUTER" are randomly arranged is approximately 3.57%.

a. To determine the number of ways the letters in the word "COMPUTER" can be arranged in a row without any restrictions, we can use the concept of permutations.

The word "COMPUTER" has 8 letters. Therefore, there are 8 positions to fill. The first position can be filled with any of the 8 letters, the second position can be filled with any of the remaining 7 letters, the third position with any of the remaining 6 letters, and so on.

So, the total number of ways the letters can be arranged in a row without any restrictions is given by 8 factorial (8!).

8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 40,320.

Therefore, there are 40,320 ways the letters in the word "COMPUTER" can be arranged in a row without any restrictions.

b. If the letters "CO" must remain next to each other (in order) as a unit, we can consider "CO" as a single entity or a block. So, we have 7 entities to arrange: "CO", "M", "P", "U", "T", "E", and "R".

Within the block "CO", the two letters can be arranged in 2 factorial (2!) ways (either "CO" or "OC"). The remaining 6 entities can be arranged in 6 factorial (6!) ways.

Therefore, the total number of ways the letters can be arranged with "CO" together as a unit is given by (2!) x (6!).

(2!) x (6!) = 2 x 720 = 1,440.

There are 1,440 ways the letters in the word "COMPUTER" can be arranged if the letters "CO" must remain next to each other (in order) as a unit.

c. To calculate the probability that the letters "CO" remain next to each other (in order) as a unit when the letters of the word "COMPUTER" are randomly arranged, we need to determine the favorable outcome and the total number of possible outcomes.

The favorable outcome is the number of ways the letters can be arranged with "CO" together as a unit, which we found to be 1,440 in part (b).

The total number of possible outcomes is the number of ways the letters can be arranged without any restrictions, which we found to be 40,320 in part (a).

Therefore, the probability is given by the favorable outcome divided by the total number of possible outcomes:

Probability = Favorable Outcome / Total Number of Outcomes

Probability = 1,440 / 40,320

Probability ≈ 0.0357 or 3.57%

So, the probability that the letters "CO" remain next to each other (in order) as a unit when the letters of the word "COMPUTER" are randomly arranged is approximately 3.57%.

Step-by-step explanation:

From the given diagram, we have two right angle triangles, ΔBCD and ΔACD, where:

We want to find the distance between boats A and B, which is line segment AB. To do this we need to subtract the length of line segment BC from the length of line segment AC.

As we have been given the side opposite the angles (CD) and wish to find the sides adjacent the angles, we can use the tangent trigonometric ratio.

[tex]\boxed{\begin{minipage}{7 cm}\underline{Tangent trigonometric ratio} \\\\$\sf \tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle.\\\end{minipage}}[/tex]

Given values:

Substitute the values into the tan ratio to create an expression for AC:

[tex]\tan 15^{\circ}=\dfrac{30}{AC}[/tex]

[tex]AC=\dfrac{30}{\tan 15^{\circ}}[/tex]

Given values:

Substitute the values into the tan ratio to create an expression for AC:

[tex]\tan 21^{\circ}=\dfrac{30}{BC}[/tex]

[tex]BC=\dfrac{30}{\tan 21^{\circ}}[/tex]

To find the length of line segment AB (the distance between boats A and B), subtract the length of line segment BC from the length of line segment AC.

[tex]\begin{aligned}\overline{AB}&=\overline{AC}-\overline{BC}\\\\&=\dfrac{30}{\tan 15^{\circ}}-\dfrac{30}{\tan 21^{\circ}}\\\\&=111.961524...-78.1526719...\\\\&=33.8088522...\\\\&=33.8\; \sf m\;(nearest\;tenth)\end{aligned}[/tex]

Therefore, the distance between the two small boats A and B is 33.8 meters (rounded to the nearest tenth).

According to the question the correct statement is: No, [tex]\(k = 2\)[/tex] is not a zero, [tex]\(p(2) = 4\)[/tex] and  [tex]\(k = 2\)[/tex] is not a zero of the polynomial.

To determine if [tex]\(k = 2\)[/tex] is a zero of the polynomial [tex]\(p(x) = 11x^4 - 26x^3 - 6x^2 + 34x - 12\),[/tex] we can use synthetic division.

[tex]\[2 & 11 & -26 & -6 & 34 & -12 \\\Matrix & & 22 & -8 & -28 & 12 \\\][/tex]

The remainder is [tex]\(12\)[/tex], not zero. Therefore, [tex]\(k = 2\)[/tex] is not a zero of the polynomial.

To find [tex]\(p(2)\)[/tex], we can substitute [tex]\(x = 2\)[/tex] into the polynomial:

[tex]\[p(2) = 11(2)^4 - 26(2)^3 - 6(2)^2 + 34(2) - 12 = 4\][/tex]

Using the first four terms of the Taylor series expansion of f(x)= ∛x  about  a=8, we can approximate ∛5 ​ as 1591/864.

To compute the coefficients for the Taylor series of the function f(x)= ∛x with a=8

we can use the formula for the coefficients of the Taylor series expansion:

Cₙ=fⁿa/n!

where fⁿa represents the  nth derivative of  f(x) evaluated at x=a.

Let's calculate the first few derivatives of f(x):

f(x)= ∛x

[tex]f'(x)=1/3x^{-2/3}[/tex]

[tex]f''(x)=-2/9x^{-5/3}[/tex]

[tex]f'''(x)=10/27x^{-8/3}[/tex]

Now, let's evaluate these derivatives at x=8:

f(8)=2

f'(8)=1/12

f''(8)=-1/54

f'''(8)=5/216

Using the formula for the coefficients, we have:

c₀=f(8)/0!= 2

c₁=f'(8)/1! = 1/12

c₂=f''(8)/2! = -1/108

c₃= f'''(8)/3! = 5/2592

Therefore, the Taylor series expansion of f(x) about a=8 is given by:

f(x)=2+1/2(x-8)-1/108(x-8)²+5/2592(x-8)³+...

To approximate ∛5 using the first four terms of this series, we substitute  x=5 into the series:

f(5)=2+1/2(5-8)-1/108(5-8)²+5/2592(5-8)³+...

Simplifying the expression, we can approximate ∛5 as

The vector pointing in the direction of the greatest increase is (-3πe^2, -1, -2π^2e - 1/e) at the point (π, 1, e).

To compute a vector pointing in the direction of the greatest increase in e(x1, x2, x3) = cos(x1x2) - x1^2x3^2 - x2ln(x3) using reverse mode Automatic Differentiation (AD), we need to compute the gradients of e with respect to each input variable at the given point (π, 1, e).

First, let's calculate the gradients:

∂e/∂x1 = -2x1x3^2 - x2x3^2sin(x1x2)

∂e/∂x2 = -ln(x3)

∂e/∂x3 = -2x1^2x3 - x2/x3

Substituting the values (π, 1, e) into the gradients, we can find the direction of greatest increase.

∂e/∂x1 = -2πe^2 - e^2sin(π) = -3πe^2

∂e/∂x2 = -ln(e) = -1

Given region R is bounded by x − 2y = 0, x + y = 4, x − 2y = −4, x + y = 1,  Hence, the correct option is 7/4.

For the given region, let's write the inequalities by finding the corner points of the region: At x - 2y = 0

=> y = x/2

On x + y = 4

=> y = 4 - x

Thus x - 2y = -4

=> y = (x+4)/2

On x + y = 1 '

=> y = 1 - x

The corner points are (0, 0), (2, 1), (0, 2), (-4, 2)

Now we will perform the variable transformation which is given by x= 3(2u+v) and y= 3(u-v).

The Jacobian of the transformation is found by taking the determinant of the following matrix which is equal to 9.

| 3(2u+v) 3(u-v) |  | 6 3 |  = 9

Let, u = (x/3 + y/3) and v = (-x/3 + y/3)

Now we can express the region R in terms of u and v in the following way: At u = 0, 2;

v = -u + 4At

u = 0, -2;

v = u+4

Thus we can express the region R as: 0 ≤ u ≤ 2, -u+4 ≤ v ≤ u+4

Now let us transform the function f(x, y) = 3xy to F(u, v)

The new function is: F(u,v) = 3(9/4)(2u+v)(u-v)

F(u,v) = (27/2)u² - (27/4)v² - (27/2)uv

The integral is given by: ∬R 3xy dA = (27/2) ∬R u² - (3/2)v² - 3uv dudv

We can integrate this over the region R as follows: ∫∫R (u² - (3/2)v² - 3uv)dudv = ∫ 0² 2² (∫ -u+4 u+4 (u² - (3/2)v² - 3uv)dv)du

Solid-state detectors are made of a solid material, such as plastic or glass, and are commonly used in nuclear physics research. They offer advantages such as high sensitivity, durability, and ease of analysis. However, they have a limited dynamic range and cannot detect low-energy particles.

Emulsion detectors, on the other hand, consist of a gel-like substance with embedded silver halide crystals. They are used in particle physics experiments and offer advantages such as high spatial resolution and the ability to detect low-energy particles. However, they have a limited shelf life, require complex analysis techniques, and can be easily damaged.

Overall, solid-state detectors are more suitable for experiments requiring high sensitivity and durability, while emulsion detectors are preferred for experiments requiring high spatial resolution and the detection of low-energy particles.

To graph the system of inequalities, we can define two variables: let x represent the number of apples Damien buys and y represent the number of oranges he buys.

Damien wants to spend no more than $12, so the first inequality is 0.30x + 0.70y ≤ 12. Damien also needs to buy at least 20 pieces of fruit, so the second inequality is x + y ≥ 20. To graph these inequalities, we plot the lines representing the equations 0.30x + 0.70y = 12 and x + y = 20. We shade the region that satisfies both inequalities.

The shaded region represents all possible combinations of apples and oranges that Damien can buy within his budget and fruit quantity requirements.

An example combination of fruit that Damien can buy would be 10 apples and 10 oranges. This combination satisfies both inequalities: 0.30(10) + 0.70(10) = 3 + 7 = 10 ≤ 12 and 10 + 10 = 20 ≥ 20. Damien would spend $3 on apples and $7 on oranges, totaling $10, which is within his $12 budget, and he would have a total of 20 pieces of fruit.

(a) To determine the number of possible 7-card poker hands that can be made from an ordinary deck of 52 playing cards, we can use the combination formula:

nCr = n! / r! (n-r)!

where n is the number of cards in the deck (52) and r is the number of cards in the hand (7).

Using this formula, we get:

nCr = 52! / 7! (52-7)! = 133,784,560

Therefore, there are 133,784,560 possible 7-card poker hands that can be made from an ordinary deck of 52 playing cards.

(b) (i) To determine the number of possible 7-card poker hands that contain at least one face card (Jack, Queen, or King), we can use the complement rule.

That is, we can find the number of 7-card poker hands that do not contain any face card and subtract it from the total number of possible 7-card poker hands.

The number of 7-card poker hands that do not contain any face card can be found by selecting all the cards from the remaining 40 cards that are not face cards, i.e. the number of 7-card hands that can be formed from a deck of 40 non-face cards.

Using the combination formula, we get:

nCr = 40! / 7! (40-7)!

= 658,008

Therefore, the number of possible 7-card poker hands that contain at least one face card is:

133,784,560 - 658,008

= 133,126,552

(ii) To determine the number of possible 7-card poker hands that contain exactly 2 Aces and 3 Kings, we can use the combination formula to select 2 Aces and 3 Kings from the deck of 4 Aces and 4 Kings, respectively.

We can then select the remaining 2 cards from the remaining 44 cards (i.e. the number of 2-card hands that can be formed from a deck of 44 cards).

Using the combination formula, we get:

nCr = 4! / 2! (4-2)! x 4! / 3! (4-3)! x 44! / 2! (44-2)!

= 6 x 4 x 946

= 22,704

The measure of one interior angle of a regular 16-gon is 157.5 degrees. This is obtained by using the formula (n-2) * 180° / n, where "n" represents the number of sides of the polygon. In this case, (16-2) * 180° / 16 = 157.5°..

To find the measure of one interior angle of a regular 16-gon, we can use the formula for the measure of an interior angle of a regular polygon:

Interior Angle = (n-2) * 180° / n

where "n" is the polygon's number of sides.

For a regular 16-gon, substituting the value of "n" into the formula, we get:

Interior Angle = (16 - 2) * 180° / 16

= 14 * 180° / 16

= 2520° / 16

= 157.5°

Therefore, the measure of one interior angle of a regular 16-gon is 157.5 degrees.

To understand the calculation, let's break it down. Equal interior angles and sides define a regular polygon. The sum of the interior angles of any polygon is given by the formula (n-2) * 180°, where "n" is the number of sides. In a regular polygon, all the interior angles are congruent, so to find the measure of one angle, we divide the sum by the number of sides.

In the case of a regular 16-gon, we subtract 2 from 16 to get 14, multiply it by 180°, and then divide by 16 to find that each interior angle measures 157.5°.

Therefore, the measure of one interior angle of a regular 16-gon is 157.5 degrees.

The given differential equation is:

dy/dx + 0.05y = x^2 + 4x + -0.5y = 3

To solve this differential equation, we can use the method of integrating factors.

First, let's rewrite the equation in standard form:

dy/dx + 0.5y = x^2 + 4x + 3

The integrating factor (IF) is given by e^(∫0.5dx) = e^(0.5x) = √(e^x)

Now, multiply both sides of the equation by the integrating factor:

√(e^x) * dy/dx + 0.5√(e^x)y = (x^2 + 4x + 3)√(e^x)

The left-hand side can be simplified using the product rule:

d/dx (√(e^x)y) = (x^2 + 4x + 3)√(e^x)

Integrating both sides with respect to x:

∫d/dx (√(e^x)y) dx = ∫(x^2 + 4x + 3)√(e^x) dx

√(e^x)y = ∫(x^2 + 4x + 3)√(e^x) dx

To evaluate the integral on the right-hand side, we can use integration by parts. Let's differentiate x^2 + 4x + 3 to get 2x + 4:

√(e^x)y = ∫(x^2 + 4x + 3)√(e^x) dx

= (x^2 + 4x + 3)√(e^x) - ∫(2x + 4)√(e^x) dx

= (x^2 + 4x + 3)√(e^x) - 2∫x√(e^x) dx - 4∫√(e^x) dx

The remaining integrals can be evaluated using standard integration techniques. Once the integrals are evaluated, we can solve for y by dividing both sides by √(e^x). The final solution will depend on the constants of integration.

ii) with 8 vertices, the degree of each vertex is 7.

iii)  the sum of the degrees of all the vertices in Ka​ is 28.

e) the relation R on set S is a partial order.

c) To ensure that 10 people have the same blood type, we can apply the Pigeonhole Principle. In this case, the "pigeons" are the people, and the "pigeonholes" are the different blood types (A, B, AB, O).

Since there are 4 different blood types, we can have at most 4 people with the same blood type. To guarantee that there are at least 10 people with the same blood type, we need to consider the worst-case scenario, where each blood type has 4 people. In this case, we would have a total of 4 * 4 = 16 people.

Therefore, to ensure that 10 people have the same blood type, we need at least 16 people in the group.

d) i) To find the number of vertices that Ka​ is composed of, we need to determine the value of "a" in the complete graph Kn​ that has 28 edges. The formula for the number of edges in a complete graph is given by:

E = n(n - 1) / 2

where E is the number of edges and n is the number of vertices.

Given that the complete graph Kn​ has 28 edges, we can set up the equation:

28 = n(n - 1) / 2

Simplifying the equation:

56 = n(n - 1)

To find the value of n, we can solve the quadratic equation:

n² - n - 56 = 0

Factoring the equation:

(n - 8)(n + 7) = 0

This gives us two potential values for n: n = 8 or n = -7. Since the number of vertices cannot be negative, we take n = 8 as the number of vertices in the complete graph Kn​.

Therefore, Ka​ is composed of 8 vertices.

ii) In a complete graph, each vertex is connected to all other vertices. Therefore, the degree of each vertex in a complete graph Kn​ is (n - 1), where n is the number of vertices.

For Ka​, with 8 vertices, the degree of each vertex is (8 - 1) = 7.

iii) To calculate the sum of the degrees of all the vertices in Ka​, we multiply the degree of each vertex by the number of vertices and divide by 2 since each edge is counted twice.

Sum of degrees = (Degree of each vertex * Number of vertices) / 2

Sum of degrees = (7 * 8) / 2

Sum of degrees = 28

Therefore, the sum of the degrees of all the vertices in Ka​ is 28.

e) i) To show that the relation R defined on set S is a partial order, we need to prove three properties: reflexivity, antisymmetry, and transitivity.

- Reflexivity: For any element x in S, (x, x) must be in R.

  In this case, for every element x in S, x is a divisor of itself, so reflexivity holds.

- Antisymmetry: If (x, y) and (y, x) are in R, then x = y.

  In this case, if x is a divisor of y and y is a divisor of x, then x = y. Antisymmetry holds since the relation only includes pairs where x is a divisor of y.

- Transitivity: If (x, y) and (y, z) are in R, then (x, z) must also be in R.

  In this case, if x is a divisor of y and y is a divisor of z, then x is a divisor of z. Transitivity holds.

Therefore, the relation R on set S is a partial order.

Let m(x) be the minimal polynomial of matrix A. Then m(A) = 0 and A*A = 0 and AM = 0

where M is the dimension of A, which means A satisfies x² = 0 and k>n equation.

Now we have that the minimal polynomial of A divides any polynomial P(x),

where P(4) = 0, which means we can write the minimal polynomial as m(x) = x².

q(x) and the degree of the minimal polynomial m(x) is less than or equal to n.

Furthermore, if A is tri potent (A³ = A) then A is diagonalizable with minimal polynomial of x² or x.

Moreover, if Ak = A, then the minimal polynomial of A has a factor of x², x, or x − A.

Finally, let A ∈ M₁ and Ak = 0 for some k > n.

Using the properties of the minimal polynomial, we can explain why Aⁿ = 0.

We know that A satisfies x² = 0, and thus the minimal polynomial of A is of degree less than or equal to 2.

Since Ak = 0, then A²k = 0, and this means that the minimal polynomial of A must divide x²k.

Since the degree of the minimal polynomial is less than or equal to 2, it must be that A² = 0.

Therefore, Aⁿ = (A²)⁽ⁿ/²⁾ = 0.

The value of S₁³ is -1.

Given that, 3x + 4y -6x - 4yTo simplify the above expression,3x - 6x + 4y - 4y=-3x

The value of -dA can be determined by finding the area of the parallelogram enclosed by the given lines.

Here, the equation of the given lines is 6x - 4y = 8 and -3x + 4y = 5 respectively.

On solving these equations, we get x = 1 and y = 1.

The point of intersection of these lines is (1, 1).

Now, we will find the points of intersection of the given lines with the axes.

For 6x - 4y = 8, putting y = 0, we get

x = 4/3For -3x + 4y = 5, putting x = 0,

we get y = 5/4

Now, we plot the points (4/3, 0), (0, 5/4), (1, 1) and (7/3, 9/4) on the graph paper and join them to form a parallelogram as shown in the diagram below:

Parallelogram enclosed by the lines 6x - 4y = 8

and -3x + 4y = 5

The area of the parallelogram is given by|dA|=|(base) (height)|

where, base = difference between the x-coordinates of the points where the parallelogram intersects the x-axis

= (7/3 - 4/3) = 1 unit Height

= difference between the y-coordinates of the points where the parallelogram intersects the y-axis

= (9/4 - 5/4) = 1 unit

|dA| = 1 × 1 = 1 unit²

Therefore, the value of -dA is -1.

Now, we need to find S₁³ - 3x + 4y = 0.

On rearranging the above equation, we get S₁³ = 3x - 4y

Substituting the values of x and y,

we gets₁³ = 3(1) - 4(1) = -1

Answer:

Step-by-step explanation:

The correct statement about the function is:

The function is positive for all real values of x where x < -6 or x > -2.

We can determine this by analyzing the given information about the graph. The fact that the parabola opens upward and passes through (-6, 0) and (-2, 0) implies that it is above the x-axis in those intervals, making it positive. The vertex of the parabola is (-4, -4), which is below the x-axis, indicating that the function is negative between -6 and -2.

Therefore, the function is positive for all real values of x where x < -6 or x > -2.

Elliptic integrals are functions that are closely related to the calculation of the arc length of an ellipse.

Since arc lengths of ellipses cannot be expressed in terms of elementary functions, so the integrals that describe them are called elliptic integrals.

Given, $f(x) = \int_0^x\frac{1}{(1+t^5)}dt$

Prepare a table of the function on the interval for $x=0(0.1)0.5$ by solving a suitable initial value problem using the Taylor series method of order 2 with h=0.1. Initial Value Problem (IVP):

The general form of a differential equation is, y′=f(x,y)

Approximating the solution to the IVP using Taylor series of order 2:We are given, h=0.1

[tex]The Taylor series method is given by,$y_{i+1} = y_i + hf(x_i,y_i) + \frac{h^2}{2} [f_x(x_i,y_i) + f_y(x_i,y_i)f(x_i,y_i)]$[/tex][tex]Using the given function, we get, $f(x_i,y_i) = \frac{1}{(1+x_i^5)}$Also, $f_x(x_i,y_i) = 0$[/tex] and [tex]$f_y(x_i,y_i) = -\frac{5x^4}{(1+x^5)^2}$[/tex]

f(x) = cos(8x)

Now,

Maclauren series is defined as ,

f(x) = f(0) + xf'(0) + x²f''(0)/2! + x³f'''(0)/3! + .......

So,

To solve for the Maclaurin series of the function, we have to differentiate the function to at least its third derivative and evaluate at for each derivative.

So differentiating f(x),

f'(x) = -8sin8x

f''(x) = -64cos(8x)

f'''(x) = 512sin(8x)
