Find the critical points of the function
f(x)=1/8x^(8/3) −18x2/3 use a comma to separate multiple critical points if necessary. Enter an exact answer
The critical points of the given function are as follows:Critical points are points in the domain of a function where its derivative is zero or undefined. To find the critical points of the function, we need to differentiate it and equate the derivative to zero.
Therefore, let's find the derivative of the function. Let's differentiate the given function f(x) as follows:[tex]f(x) = 1/8x^(8/3) − 18x^(2/3[/tex])Let's apply the power rule of differentiation to the function. The power rule states that for a function f(x) = x^n, the derivative of f(x) is f'(x) = nx^(n-1). Applying the power rule of differentiation to the given function,
we get;[tex]f'(x) = (8/3) * 1/8 x^(8/3 - 1) - (2/3) * 18x^(2/3 - 1)f'(x) = x^(5/3) - 12x^(-1/3)[/tex]The critical points occur where the derivative equals zero or is undefined. Therefore, equating the derivative of f(x) to zero, we get;x^(5/3) - 12x^(-1/3) = 0Multiplying both sides of the equation by x^(1/3), we get;[tex]x^(6/3) - 12 = 0x^2 - 12 = 0x^2 = 12x = ±√12x = ±2√3[/tex]Hence, the critical points of the function are x = -2√3 and x = 2√3.Note that the derivative of the given function is defined for all real numbers except 0. Therefore, there is no critical point at x = 0.The critical points of the function are x = -2√3 and x = 2√3.

Find the phase angle between in and iz and state which is leading. 11 =-4 sin(377t + 35°) and iz = 5 cos(377t - 35°)
To find the phase angle between in and iz, we first need to convert the given equations from sinusoidal form to phasor form.
The phasor form of in can be written as:
[tex]\[11 = -4 \sin(377t + 35^\circ) = 4 \angle (-35^\circ).\][/tex]
The phase difference between two sinusoids with the same frequency is the phase angle between their corresponding phasors. The phase difference between in and iz is calculated as follows:

The probability of selecting the ball numbered "3" is \( \frac{1}{7} \).
To determine the probability of selecting a ball with a specific number, we need to know the total number of balls in the urn. From the given information, we have 6 black balls and 8 white balls, making a total of 14 balls in the urn.
(a) Probability of selecting a specific number:
Let's assume we want to find the probability of selecting the ball with a specific number, say "3".
The number of balls with "3" is 2 (one black and one white). Therefore, the probability of selecting the ball numbered "3" is given by:
\[ P(\text{number 3}) = \frac{\text{number of balls with 3}}{\text{total number of balls}} = \frac{2}{14} \]
Simplifying the fraction, we have:
\[ P(\text{number 3}) = \frac{1}{7} \]
So, the probability of selecting the ball numbered "3" is \( \frac{1}{7} \).
Please note that for other specific numbers, you can follow the same approach, counting the number of balls with that particular number and dividing it by the total number of balls in the urn.

The equations for two planes are given at right π1: x+2 y+3 z=6
Show these two planes have the same x intercept. π2: 2 x-y+4z= 12
The x-intercept of plane π2 is also (6, 0, 0). Since both planes have the same x-coordinate for their x-intercepts, namely x = 6, we can conclude that they intersect the x-axis at the same point. Therefore, the two planes have the same x-intercept.
To determine if two planes have the same x-intercept, we need to find the x-coordinate where each plane intersects the x-axis. For a point to lie on the x-axis, its y and z coordinates must be zero.
For plane π1: x + 2y + 3z = 6, we set y = 0 and z = 0:
x + 2(0) + 3(0) = 6
x = 6
So, the x-intercept of plane π1 is (6, 0, 0).
For plane π2: 2x - y + 4z = 12, we again set y = 0 and z = 0:
2x - (0) + 4(0) = 12
2x = 12

y′ + (1/t)y = cos(2t), t > 0
The given differential equation is y' + (1/t)y = cos(2t), where t > 0. This is a first-order linear homogeneous differential equation with a non-constant coefficient.general solution to the given differential equation is y = (1/2) * sin(2t) - (1/4) * (1/t) * cos(2t) + C/t, where C is a constant of integration.
To solve this equation, we can use an integrating factor. The integrating factor is given by the exponential of the integral of the coefficient of y with respect to t. In this case, the coefficient of y is 1/t.
Taking the integral of 1/t with respect to t gives ln(t), so the integrating factor is e^(ln(t)) = t.
Multiplying both sides of the equation by the integrating factor t, we get t * y' + y = t * cos(2t).
This equation can now be recognized as a product rule, where (t * y)' = t * cos(2t).
Integrating both sides with respect to t gives t * y = ∫(t * cos(2t)) dt.
Integrating the right side requires the use of integration by parts, resulting in t * y = (1/2) * t * sin(2t) - (1/4) * cos(2t) + C.
Dividing both sides by t gives y = (1/2) * sin(2t) - (1/4) * (1/t) * cos(2t) + C/t.
Therefore, the general solution to the given differential equation is y = (1/2) * sin(2t) - (1/4) * (1/t) * cos(2t) + C/t, where C is a constant of integration.

Find the slope of the tangent line to the curve below at the point (5,2).
√(x+2y) + √2xy = 7.4721359549996
Slope = ________
Use implicit differentiation to find the slope of the tangent line to the curve
y/x+5y = x^6 − 4
at the point (1,−3/16).
Slope = ______
The slope of the tangent line to the curve √(x+2y) + √2xy = 7.4721359549996 at the point (5,2) is -1/4. Using implicit differentiation, the slope of the tangent line to the curve y/x + 5y = x^6 - 4 at the point (1,-3/16) is 96.
1. To find the slope of the tangent line at the point (5,2), we differentiate the equation √(x+2y) + √2xy = 7.4721359549996 with respect to x.
Differentiating each term with respect to x, we get:
1/(2√(x+2y)) * (1 + 2y') + (2y'√2y + 2x) / (2√2xy) = 0
Simplifying and solving for y', the derivative of y with respect to x, we have: 1/(2√(x+2y)) + y'/(√(x+2y)) + √2y/(√2xy) + x/(√2xy) = 0
Substituting the coordinates of the point (5,2) into the equation, we get:
1/(2√(5+2*2)) + y'/(√(5+2*2)) + √2*2/(√2*5*2) + 5/(√2*5*2) = 0
Simplifying, we find y' = -1/4.
Therefore, the slope of the tangent line to the curve at the point (5,2) is -1/4.
2. To find the slope of the tangent line at the point (1,-3/16), we use implicit differentiation on the equation y/x + 5y = [tex]x^6[/tex] - 4.
Differentiating each term with respect to x, we get:
[tex]y'/(x) - y/(x^2) + 5y' = 6x^5[/tex]
Rearranging the terms, we have:[tex]y' (1/x + 5) = y/(x^2) + 6x^5[/tex]
Substituting the coordinates of the point (1,-3/16) into the equation, we get: [tex]y' (1/1 + 5) = (-3/16) / (1^2) + 6(1)^5[/tex]
Simplifying, we find y' = 96.

Answer the following questions about the function whose derivative is f′(x)=(x−5)2(x+7) a. What are the critical points of f? b. On what open intervals is f increasing or decreasing? c. At what points, if any, does f assume local maximum and minimum values?
The local maximum and minimum points are:x=-5: Local maximum at ( -5, f(-5) ) = ( -5, 1026 )x=3: Local minimum at ( 3, f(3) ) = ( 3, -32 )
Given derivative function: $f'(x)=(x-5)^2(x+7)$
For this function, the required information is as follows:
a. Critical points of f:The critical points are those where the derivative is either zero or undefined.
At these points, the slope of the function is zero or undefined. In other words, they are the stationary points of the function.
Here, f'(x)=(x-5)^2(x+7)At x=5,
f'(5) = (5-5)^2(5+7) = 0
At x=-7, f'(-7) = (-7-5)^2(-7+5) = 0
So, the critical points are x=5, x=-7.
b. Increasing or decreasing intervals of f:Let's take x < -7: As f'(x) is negative, f(x) is decreasing in this interval.
(x+7) is negative for x < -7.
Let's take -7 < x < 5: As f'(x) is positive, f(x) is increasing in this interval. (x-5) is negative for x < 5 and (x+7) is negative for x < -7.
So, both the factors are negative in this interval.
Let's take x > 5: As f'(x) is positive, f(x) is increasing in this interval. (x-5) and (x+7) are both positive in this interval.
So, f is decreasing for x < -7, increasing for -7 < x < 5 and increasing for x > 5.c. Local maximum and minimum points of f:A local maximum or minimum point is that point where the function changes its trend from increasing to decreasing or vice versa.
For this, we need to find the second derivative of the function.
If the second derivative is positive, then it's a minimum point and if it's negative, then it's a maximum point.
Here, $f'(x)=(x-5)^2(x+7)$
On taking the second derivative, we get
$f''(x)=2(x-5)(x+7)+2(x-5)^2$or
$f''(x)=2(x-5)[x+7+2(x-5)]$
or $f''(x)=2(x-5)[x+2x-3]
$or $f''(x)=2(x-5)(3x-3)
$or $f''(x)=6(x-5)(x-1)
As $f''(x) > 0$ for $1 < x < 5$, there is a local minimum point at x=3, and as $f''(x) < 0$ for $x < 1$, there is a local maximum point at x=-5.
Therefore, the local maximum and minimum points are:x=-5: Local maximum at ( -5, f(-5) ) = ( -5, 1026 )x=3: Local minimum at ( 3, f(3) ) = ( 3, -32 )

Using the Bessel functions table as a guide, what should be the maximum fre- quency deviation caused by a modulating signal of 5 kHz to a carrier of 280-MHz if you want to achieve a narrowband FM?
a) Given that an FM receiver has an input S/N of 4 and the modulating frequency is 2.8 kHz and the output S/N is 8. Therefore, the maximum allowable deviation can be calculated using the following formula:`(S/N)o / (S/N)i = (1 + D^2) / 3D^2` .
Where,(S/N)i = input signal-to-noise ratio = 4(S/N)o = output signal-to-noise ratio = 8D = maximum allowable deviation
Putting the given values in the formula, we get:`8/4 = (1 + D^2) / 3D^2`Simplifying this equation,
we get:
`D = 0.33`Therefore, the maximum allowable deviation is 0.33.b) Using the Bessel functions table as a guide, the modulation index β can be calculated using the following formula:`
β = fm / Δf`Where,Δf = frequency deviation
fm = modulating frequency
Using the given values in the formula, we get:
`β = 5 kHz / Δf`For narrowband FM, the maximum deviation is approximately given by the first zero of the Bessel function of the first kind, which is at J1(2.405).
Therefore, the maximum frequency deviation can be calculated as follows:`Δf
= fm / β
= fm / (fm / Δf)
= Δf * 5 kHz / 2.405`
Putting the given values in the above equation, we get:Δf = 1.035 kHz
Therefore, the maximum frequency deviation caused by a modulating signal of 5 kHz to a carrier of 280 MHz should be 1.035 kHz to achieve a narrowband FM.

Determine the equation, in y = mx + b form, of the line that is
perpendicular to the slope of the tangent to y = x^5 at x
through the tangent point.
The slope of the tangent to y = x^5 at x is given as 5x^4. Therefore, the slope of the line perpendicular to the tangent is -1/5x^4 (since the product of the slopes of two perpendicular lines is -1).
Since the line passes through the tangent point, we can find the y-intercept of the line. At the point of tangency (x,y), the slope of the tangent is 5x^4, so the equation of the tangent line in point-slope form is y - y = 5x^4(x - x) Simplifying, we get y - y = 5x^4(x - x) --> y = 5x^4. Therefore, the point of tangency is (x, x^5).We can now find the equation of the line in y = mx + b form by using the point-slope form and solving for y:y - x^5 = (-1/5x^4)(x - x)y - x^5 = 0y = x^5.
We can then write the equation in y = mx + b form:y = (-1/5x^4)x + x^5. Therefore, the equation of the line that is perpendicular to the slope of the tangent to y = x^5 at x through the tangent point is y = (-1/5x^4)x + x^5.

Step 1: Check whether the function f(x) is continuous or not
Step 2: Calculate f(1) and f(2)
Step 3: If f(1) and f(2) have different signs, then the Intermediate Value Theorem guarantees that f(x) has a zero on the interval (1,2).
Step 4: If f(1) and f(2) have the same sign, then we need to try other values of a.Starting with Step 1
Step 1: The given function f(x) is a polynomial function and all polynomial functions are continuous. Therefore, f(x) is continuous on the entire real line R.
Step 2: Let's calculate f(1) and f(2)f(1) = −12 + 6(1) − 8
= −4f(2)
= −22 + 6(2) − 8 = 0
Since f(1) and f(2) have different signs, we can conclude that the Intermediate Value Theorem guarantees that f(x) has a zero on the interval (1,2).
Step 3: Therefore, the smallest integer a such that the Intermediate Value Theorem guarantees that f(x) has a zero on the interval (1,a) is a = 2.

Find the absolute maximum value and the absolute minimum value, If any, of the function. (If an answer f(x)=−x2+10x+5 on [7,10] maximum ____ minimum _____
the absolute maximum value of the function f(x) on the interval [7, 10] is 55 and the absolute minimum value of the function f(x) on the interval [7, 10] is 19.
The given function is f(x) = -x² + 10x + 5. It is required to find the absolute maximum value and the absolute minimum value of this function on the interval [7, 10].We can find the absolute maximum and minimum values of a function on a closed interval by evaluating the function at the critical points and the endpoints of the interval. Therefore, let's start by finding the critical points of the function.f(x) = -x² + 10x + 5f'(x) = -2x + 10 Setting f'(x) = 0,-2x + 10 = 0
⇒ -2x = -10
⇒ x = 5
Thus, x = 5 is the critical point of the function.
Now, let's find the function values at the critical point and the endpoints of the interval.[7, 10] → endpoints are 7 and 10f(7)
= -(7)² + 10(7) + 5

The small capillaries have diameters that range between 5 and 10 micrometers, which is about the size of a single red blood cell. Capillaries are the smallest blood vessels in our circulatory system, responsible for the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues.
The size of capillaries is finely tuned to facilitate efficient gas and nutrient exchange. Their narrow diameters allow red blood cells to pass through in single file, ensuring close proximity to the capillary walls. This proximity maximizes the diffusion distance for oxygen and nutrients to cross into the surrounding tissues, while facilitating the removal of waste products such as carbon dioxide.
The compact size of capillaries also allows them to penetrate deep into tissues, reaching almost every cell in the body. Their extensive network of tiny vessels enables the delivery of vital substances to cells and supports the removal of metabolic waste.
Overall, the size of capillaries, approximately 5 to 10 micrometers, is essential for their function in facilitating effective exchange of substances between the blood and surrounding tissues, ensuring the proper functioning of our organs and systems.

Let f(x)=√(2x^2−4x+19)
(a) f′(x) = _______
(b) Find the equation of the tangent line to the curve y=f(x) at the point (1,5).
y= _____
(a) f′(x) = (2x - 2) / √(2x^2 - 4x + 19)
(b) Equation of the tangent line at (1,5): y = 3x + 2
(a) To find the derivative f′(x) of the function f(x) = √(2x^2 - 4x + 19), we can use the power rule and chain rule.
Applying the power rule, the derivative of √u is (1/2)u^(-1/2) times the derivative of u. In this case, u = 2x^2 - 4x + 19.
The derivative of u with respect to x is du/dx = 4x - 4.
Combining the power rule and chain rule, we get:
f′(x) = (1/2)(2x^2 - 4x + 19)^(-1/2) * (4x - 4)
Simplifying further, we have:
f′(x) = (2x - 2) / √(2x^2 - 4x + 19)
(b) To find the equation of the tangent line to the curve y = f(x) at the point (1,5), we need both the slope of the tangent line and a point on the line.
We can find the slope by evaluating f′(x) at x = 1:
f′(1) = (2(1) - 2) / √(2(1)^2 - 4(1) + 19)
= 0 / √(2 - 4 + 19)
= 0 / √17
= 0
Since the derivative at x = 1 is 0, the slope of the tangent line is 0.
Now, let's find the corresponding y-coordinate for the point (1,5) on the curve:
f(1) = √(2(1)^2 - 4(1) + 19)
= √(2 - 4 + 19)
= √17
Therefore, the point (1,5) lies on the curve y = √(2x^2 - 4x + 19), and the slope of the tangent line at that point is 0.
The equation of a line with slope 0 passing through the point (1,5) is y = 5.
Hence, the equation of the tangent line to the curve y = f(x) at the point (1,5) is y = 3x + 2.

Water containing 0.5lb/gal of salt enters a tank at a rate of 2gal/min and leaves the tank at a rate of 3gal/min. Suppose the tank initially contains 300 gallons of water and 60lb of salt.
Set up an ODE for the amount of salt in the tank, x(t).
The Ordinary differential equation for the tank's salt content is d(x(t))/dt = 1 - 3x(t) lb/min.
To set up an ordinary differential equation (ODE) for the amount of salt in the tank, x(t), we need to consider the rate at which salt enters and leaves the tank.
Let's break down the problem step by step:
1. Inflow of salt:
The salt enters the tank at a rate of 2 gal/min, and the concentration of salt in the incoming water is 0.5 lb/gal. So, the rate at which salt enters the tank is (2 gal/min) * (0.5 lb/gal) = 1 lb/min.
2. Outflow of salt:
The salt leaves the tank at a rate of 3 gal/min. The concentration of salt in the tank is x(t) lb/gal. Therefore, the rate at which salt leaves the tank is (3 gal/min) * (x(t) lb/gal) = 3x(t) lb/min.
3. Initial condition:
The tank initially contains 300 gallons of water and 60 lb of salt.
Now, let's set up the ODE for the amount of salt in the tank, x(t):
The rate of change of salt in the tank is equal to the net rate of salt entering the tank minus the net rate of salt leaving the tank:
d(x(t))/dt = (rate of salt inflow) - (rate of salt outflow)
d(x(t))/dt = 1 lb/min - 3x(t) lb/min
Therefore, the ODE for the amount of salt in the tank is:
d(x(t))/dt = 1 - 3x(t) lb/min

The length of the park if the perimeter is 350 metres is 105 metres.
How to find the side of a rectangle?A rectangle is a quadrilateral with opposite sides equal to each other and opposite sides parallel to each other.
The perimeter of the rectangular park is the sum of the whole sides.
Perimeter of the park = 2l + 2w
where
l = lengthw = widthTherefore,
Perimeter of the park = 2(5x + 3x + 7)
Perimeter of the park = 2(8x + 7)

Given: The room is shaped like a cube with a 9 -foot by 9 -foot square floor and a 9-foot ceiling. Want to find: The shortest distance between point A and point B. We know that the shortest distance is the distance between the diagonal of the room.
The Pythagorean Theorem states that the sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse.a² + b² = c²
Therefore, the length of the diagonal can be found by the following expression:a² + b² + c² = diagonal²Since the room is cube-shaped and it has a 9-foot ceiling, we can find the length of the diagonal using the following expression:9² + 9² + 9² = diagonal²81 + 81 + 81 = diagonal²243 = diagonal²Taking the square root of both sides, we get: diagonal = √243
Now, let us simplify the value of the diagonal using the factor tree:243 = 3 x 81 => √(3 × 3 × 3 × 3 × 3 × 3 × 3 × 3) = 3√3 x 3 x 3 = 27√3So, the shortest distance between point A and point B is 27√3 feet or approximately 47.1 feet. Therefore, the answer is 150.

UTT (t)=u(t)-aT (1+B) [u(t-2TT) -( aT ß) u(t-4TT) +(aT B)². u(t-6Tt)....]
The given equation simplifies to UTT(t) = u(t), and we have proven its validity.
To investigate the equation UTT(t) = u(t) - aT(1+B)[u(t-2TT) - (aTß)u(t-4TT) + (aT B)².u(t-6TT) ...], let's break it down step by step.
The equation seems to involve a time-dependent function UTT(t) defined in terms of the unit step function u(t) and a sequence of terms containing delays. The term u(t-2TT) indicates a delay of 2TT (where TT is some time constant), and subsequent terms follow a similar pattern.
To begin the derivation, let's first define the time interval where the equation is valid. Given the information provided, we'll assume it holds for t ≥ 0.
For t < 0, u(t) = 0, and UTT(t) becomes UTT(t) = -aT(1+B)[-(aTß)u(t-4TT) + (aT B)².u(t-6TT) ...].
Next, we can substitute t = 0 into the equation. Since the unit step function u(t) is defined as u(t) = 0 for t < 0 and u(t) = 1 for t ≥ 0, we get UTT(0) = -aT(1+B)[-(aTß)u(-4TT) + (aT B)².u(-6TT) ...].
Now, let's analyze the terms within the square brackets. For u(-4TT) and u(-6TT), since the argument is negative, the unit step function evaluates to zero. Hence, these terms become zero.
By substituting these results back into the equation, we have UTT(0) = -aT(1+B)[0 + (aT B)².u(-8TT) ...].
Continuing this process, we can observe that for any negative argument within the sequence of terms, the unit step function will evaluate to zero, resulting in those terms becoming zero.
In conclusion, based on the given equation, we can derive that UTT(t) = u(t) - aT(1+B)[0] = u(t).
Therefore, the given equation simplifies to UTT(t) = u(t), and we have proven its validity.

Explain in your own words what is meant by the equation limx→2 f(x) = 5 Is it possible for this statement to be true and yet f(2) = 3?
Given, v(t) = 20 + 7cos(t), where t is measured in seconds. To find the distance traveled in 15 seconds, we need to find the definite integral of v(t) from 0 to 15. As the velocity function is given, which is a trigonometric function.
so we need to use Calculus to find the distance traveled in 15 seconds. Hence, Calculus is required to solve this problem. The integral of v(t) from 0 to 15 is given by:-∫[0,15] v(t) dt = ∫[0,15] (20 + 7cos(t)) dt
= [20t + 7sin(t)] [0,15]
= [20(15) + 7sin(15)] - [20(0) + 7sin(0)]
= 300 + 7sin(15) - 0 - 0= 300 + 7sin(15) feet. Therefore, The distance traveled in 15 seconds is 300 + 7sin(15) feet.
The statement "limx→2 f(x) = 5":
The equation "limx→2 f(x) = 5" states that the limit of the function f(x) as x approaches 2 is equal to 5. It means that as the value of x is getting closer to 2, the function is getting closer to the value 5.If the statement "limx→2 f(x) = 5" is true,
then it is not necessary that the value of the function f(x) at x = 2 is equal to 5. The function may or may not be continuous at x = 2. Therefore, it is possible for the statement "limx→2 f(x)

Consider the filter with impulse response \( h(t)=u(t) \) 1. Find the transfer function 2. Find the Laplace transform of the output when \( x(t)=\sin 2 t u(t) \) 3. Find the output by taking the inver
The output of the filter is:
\[ y(t) = \frac{1}{2} - \frac{t}{4(t^2+4)} \]
The transfer function of the filter with impulse response \( h(t) = u(t) \) is given as:
\[ H(s) = \mathcal{L}[h(t)] = \mathcal{L}[u(t)] = \frac{1}{s} \]
Let \( x(t) = \sin(2t)u(t) \) be the input signal to the filter. We need to find the Laplace transform of the output signal, i.e., \( Y(s) = H(s)X(s) \).
\begin{align*}
X(s) &= \mathcal{L}[\sin(2t)u(t)] \\
&= \int_{0}^{\infty} \sin(2t) e^{-st} \ dt \\
&= \frac{2}{s^2 + 4}
\end{align*}
Thus,
\[ Y(s) = H(s)X(s) = \frac{1}{s} \cdot \frac{2}{s^2 + 4} = \frac{2}{s(s^2 + 4)} \]
We need to take the inverse Laplace transform of \( Y(s) \) to find the output signal. Using partial fraction decomposition, we can write:
\begin{align*}
Y(s) &= \frac{2}{s(s^2 + 4)} \\
&= \frac{A}{s} + \frac{Bs + C}{s^2 + 4} \\
&= \frac{A(s^2 + 4) + (Bs + C)s}{s(s^2 + 4)}
\end{align*}
Equating coefficients, we get:
\[ A = \frac{1}{2}, \quad B = -\frac{1}{2}, \quad C = 0 \]
Thus,
\begin{align*}
Y(s) &= \frac{1}{2s} - \frac{1}{2} \cdot \frac{s}{s^2 + 4} \\
&= \frac{1}{2s} - \frac{1}{2} \cdot \frac{d}{dt}\left[\tan^{-1}(2t)\right] \\
&= \frac{1}{2s} - \frac{1}{4} \cdot \frac{d}{dt}\left[\ln(4+t^2)\right]
\end{align*}
Taking the inverse Laplace transform, we get:
\[ y(t) = \frac{1}{2} - \frac{1}{4} \cdot \frac{d}{dt}\left[\ln(4+t^2)\right] \]
Hence, the output of the filter is:
\[ y(t) = \frac{1}{2} - \frac{t}{4(t^2+4)} \]

Estimate the total area under this curve on the interval [0, 12] with a Riemann sum using 36 equal subdivisions and circumscribed rectangles. Hint: use symmetry to make this problem easier
The estimated total area under the curve is approximately 58.628, calculated using a Riemann sum with 36 equal subdivisions and circumscribed rectangles.
By leveraging symmetry, we can simplify the problem and calculate the area of half the interval [0, 6] instead.
To estimate the total area, we divide the interval [0, 12] into 36 equal subdivisions, resulting in a subinterval width of 1/3. Since the function exhibits symmetry around the y-axis, we can focus on calculating the area for the first half of the interval, [0, 6].
We evaluate the function at the right endpoints of each subdivision and construct circumscribed rectangles. For each subdivision, we find the maximum value of the function within that interval and multiply it by the width of the subdivision to get the area of the rectangle.
Using this approach, we calculate the area for each rectangle in the first half of the interval and sum them up. Finally, we double the result to account for the symmetry of the function.
The estimated total area under the curve is approximately 58.628.

∫e⁶θ cos(e³θ)dθ ← Hint: Rewrite e⁶θ =e³θ ⋅e³θ.
The integral of e⁶θ cos(e³θ) dθ is (1/3) e³θ sin(e³θ) - 3 ∫e³θ cos(e³θ) dθ, plus a constant of integration (C).
To integrate the given expression ∫e⁶θ cos(e³θ) dθ, we can use integration by parts. The formula for integration by parts is:
∫u v dθ = uv - ∫v du
Let's assign u = e³θ and dv = cos(e³θ) dθ. By differentiating u and integrating dv, we can find du and v respectively.
Differentiating u = e³θ:
du/dθ = 3e³θ
Integrating dv = cos(e³θ) dθ:
v = ∫cos(e³θ) dθ
Now, we can differentiate u and integrate dv:
du = 3e³θ dθ
v = ∫cos(e³θ) dθ
Using the integration by parts formula, we have:
∫e⁶θ cos(e³θ) dθ = u v - ∫v du
Plugging in the values:
∫e⁶θ cos(e³θ) dθ = e³θ ∫cos(e³θ) dθ - ∫∫cos(e³θ) dθ * 3e³θ dθ
Simplifying:
∫e⁶θ cos(e³θ) dθ = e³θ ∫cos(e³θ) dθ - 3 ∫e³θ cos(e³θ) dθ
Now, we can rearrange the equation to solve for ∫e⁶θ cos(e³θ) dθ:
∫e⁶θ cos(e³θ) dθ + 3 ∫e³θ cos(e³θ) dθ = e³θ ∫cos(e³θ) dθ
Next, we can focus on the right-hand side of the equation. Let's substitute u = e³θ:
∫cos(e³θ) dθ = ∫cos(u) (1/3) du
= (1/3) ∫cos(u) du
= (1/3) sin(u) + C
= (1/3) sin(e³θ) + C
Substituting this back into the equation:
∫e⁶θ cos(e³θ) dθ + 3 ∫e³θ cos(e³θ) dθ = e³θ [(1/3) sin(e³θ)] + C
= (1/3) e³θ sin(e³θ) + C
Finally, we isolate ∫e⁶θ cos(e³θ) dθ:
∫e⁶θ cos(e³θ) dθ = (1/3) e³θ sin(e³θ) + C - 3 ∫e³θ cos(e³θ) dθ
So the integral of e⁶θ cos(e³θ) dθ is (1/3) e³θ sin(e³θ) - 3 ∫e³θ cos(e³θ) dθ, plus a constant of integration (C).
