In order to find the vector U4, first, we need to orthonormalize ū, Ū2, U3, and then apply the Gram-Schmidt process. We know that a set of vectors is orthonormal if each vector has length 1 and is perpendicular to the others.So, the vector ū1 is already normalized, we will use it in the Gram-Schmidt process for finding Ū2. The formula for the Gram-Schmidt process is given by;$$v_{k} = u_{k} - \sum_{j=1}^{k-1} \frac{\langle u_k,v_j \rangle}{\langle v_j,v_j\rangle}v_{j} $$We will start by orthonormalizing the vector Ū2 with respect to ū1.
Thus, we have to apply the above formula:$$v_2=u_2 - \frac{\langle u_2,u_1\rangle}{\langle u_1,u_1\rangle}u_1$$$$v_2= \begin{bmatrix} -0.5 \\ -0.5 \\ 0.5 \\ 0.5 \end{bmatrix} -\frac{1}{2}\begin{bmatrix} 0.5 \\ 0.5 \\ 0.5 \\ 0.5 \end{bmatrix}$$$$v_2=\begin{bmatrix} -1 \\ -1 \\ 1 \\ 1 \end{bmatrix} $$Let's normalize this vector:$$||v_2|| = \sqrt{(-1)^2 + (-1)^2 + 1^2 + 1^2 }=\sqrt{4}=2$$$$\Rightarrow \ \hat{v_2} = \frac{1}{2}v_2=\frac{1}{2}\begin{bmatrix} -1 \\ -1 \\ 1 \\ 1 \end{bmatrix}=\begin{bmatrix} -1/2 \\ -1/2 \\ 1/2 \\ 1/2 \end{bmatrix} $$Next, we have to orthonormalize the vector U3 with respect to ū1 and Ū2. Again, we have to apply the Gram-Schmidt process:$$v_3 = u_3 - \frac{\langle u_3,v_1 \rangle}{\langle v_1,v_1\rangle}v_1 - \frac{\langle u_3,v_2 \rangle}{\langle v_2,v_2\rangle}v_2$$$$v_3 = \begin{bmatrix} 0.5 \\ -0.5 \\ 0.5 \\ -0.5 \end{bmatrix} -\frac{1}{2}\begin{bmatrix} 0.5 \\ 0.5 \\ 0.5 \\ 0.5 \end{bmatrix}-\frac{-1}{4}\begin{bmatrix} -1 \\ -1 \\ 1 \\ 1 \end{bmatrix}$$$$v_3 = \begin{bmatrix} 0.5 \\ -0.5 \\ 0.5 \\ -0.5 \end{bmatrix} -\begin{bmatrix} 0.25 \\ 0.25 \\ 0.25 \\ 0.25 \end{bmatrix}+\frac{1}{4}\begin{bmatrix} -1 \\ -1 \\ 1 \\ 1 \end{bmatrix}$$$$v_3 = \begin{bmatrix} 0.25 \\ -0.75 \\ 0.75 \\ -0.25 \end{bmatrix} $$Normalizing, we have:$$||v_3|| = \sqrt{(0.25)^2 + (-0.75)^2 + 0.75^2 + (-0.25)^2 }=\sqrt{1}=1$$$$\Rightarrow \ \hat{v_3} = \begin{bmatrix} 0.25 \\ -0.75 \\ 0.75 \\ -0.25 \end{bmatrix} $$

Find the volume of the solid obtained by rotating the region bounded by the curves y = x3, y = 8, and the y-axis about the x-axis. Evaluate the following integrals. Show enough work to justify your answers. State u-substitutions explicitly. 3.7 5x In(x3) dx
The problem involves finding the volume of the solid obtained by rotating the region bounded by the curves y = x^3, y = 8, and the y-axis about the x-axis. The specific integral to be evaluated is[tex]\int\limits3.7 5x ln(x^3)[/tex] dx. In order to solve it, we will need to perform a u-substitution and show the necessary steps.
To evaluate the integral ∫3.7 5x ln(x^3) dx, we can start by making a u-substitution. Let's set u = x^3, so du = 3x^2 dx. We can rewrite the integral as follows[tex]\int\limits 3.7 5x ln(x^3) dx = \int\limits3.7 (1/3) ln(u) du[/tex]
Next, we can pull the constant (1/3) outside of the integral: [tex](1/3) \int\limits3.7 ln(u) du[/tex]
Now, we can integrate the natural logarithm function. The integral of ln(u) is u ln(u) - u + C, where C is the constant of integration. Applying this to our integral, we have:
[tex](1/3) [u ln(u) - u] + C[/tex]
Substituting back u = x^3, we get: [tex](1/3) [x^3 ln(x^3) - x^3] + C[/tex]
This is the antiderivative of 5x ln(x^3) with respect to x. To find the volume of the solid, we need to evaluate this integral over the appropriate limits of integration and perform any necessary arithmetic calculations.
By evaluating the integral and performing the necessary calculations, we can determine the volume of the solid obtained by rotating the given region about the x-axis.

a witness to a hit-and-run accident tells the police that the license plate of the car in the accident, which contains three letters followed by three digits, starts with the letters as and contains both the digits 1 and 2. how many different license plates can fit this description?
There are 140 different license plates that can fit the description provided by the witness of a hit-and-run accident. There are 1,689,660 different license plates that can fit the given description.
To find the number of different license plates that match the given description, we need to consider the available options for each position in the license plate.
The first position is fixed with the letters "as". Since there are no restrictions on these letters, they can be any two letters of the alphabet, resulting in 26 × 26 = 676 possible combinations.
The second position can be filled with any letter of the alphabet except "s" (since it is already used in the first position). This gives us 26 - 1 = 25 options.
Similarly, the third position can also have 25 options, as we need to exclude the letter "s" and the letter used in the second position.
For the fourth position (the first digit), there are 10 options (0-9).
The fifth position can be either 1 or 2, giving us 2 options.
Finally, the sixth position (the second digit) can also be filled with any of the remaining 10 options.
To find the total number of combinations, we multiply the options for each position: 676 × 25 × 25 × 10 × 2 × 10 = 1,690,000.
However, we need to exclude the cases where the digits 1 and 2 are not present together. So, we subtract the cases where the first digit is not 1 or 2 (8 options) and the cases where the second digit is not 1 or 2 (9 options): 1,690,000 - (8 × 2 × 10) - (10 × 9 × 2) = 1,690,000 - 160 - 180 = 1,689,660.
Therefore, there are 1,689,660 different license plates that can fit the given description.

Find the derivative of the function. f(x) = Inc 4x3 In()
The derivative of the function f(x) = ln(4x^3) can be found using the chain rule, resulting in f'(x) = (12x^2)/x = 12x^2.
To find the derivative of the given function f(x) = ln(4x^3), we apply the chain rule. The chain rule states that if we have a composition of functions, such as f(g(x)), where f and g are differentiable functions, then the derivative of f(g(x)) with respect to x is given by f'(g(x)) * g'(x).
In this case, our outer function is ln(x), and our inner function is 4x^3. Applying the chain rule, we differentiate the outer function with respect to the inner function, which gives us 1/(4x^3). Then, we multiply this by the derivative of the inner function, which is 12x^2.
Combining these results, we have f'(x) = 1/(4x^3) * 12x^2. Simplifying further, we get f'(x) = (12x^2)/x, which can be simplified as f'(x) = 12x^2.
Therefore, the derivative of f(x) = ln(4x^3) is f'(x) = 12x^2.

9. The equation of the plane is x - 2y - 3z - 23 = 0. 10. The line intersects the plane at t = -11/2.
9. We can first find the direction vector of the line by subtracting the two given points:[x,y,z]=[3,3,-2]+t[1,2,-3]⟹[x,y,z]=[3+t,3+2t,-2-3t] The direction vector of the line is [1,2,-3].

The equation of the tangent plane at the point P(-1, 2, -9) for the surface defined by z = 3x^2 + 3xy is given by 2x + y - 9z = -1.
To find the equation of the tangent plane at a given point, we need to determine the partial derivatives of the surface equation with respect to each variable (x, y, and z) and evaluate them at the point of interest.
Given the surface equation z = 3x^2 + 3xy, we can calculate the partial derivatives as follows:
∂z/∂x = 6x + 3y
∂z/∂y = 3x
Evaluating these derivatives at the point P(-1, 2, -9), we have:
∂z/∂x = 6(-1) + 3(2) = -6 + 6 = 0
∂z/∂y = 3(-1) = -3
The equation of the tangent plane can be written as:
0(x - (-1)) - 3(y - 2) + (z - (-9)) = 0
0x - 0y - 3y + z + 9 = 0

To evaluate the integral ∫[2f(x) + 3g(x)] dx, given that ∫f(x) dx = 35 and ∫g(x) dx = 16, we can use the properties of integrals to simplify the expression and apply the given information. Value of the integral ∫[2f(x) + 3g(x)] dx is equal to 118.

Find the absolute extreme values of (x) = x^4 − 16x^3 +

To find the absolute extreme values of the function \(f(x) = x^4 - 16x^3 + 70x^2\) on the interval \([-1, 6]\), we need to evaluate the function at the critical points and endpoints within the given interval.
Step 1: Find the critical points by taking the derivative of \(f(x)\) and setting it equal to zero:
\(f'(x) = 4x^3 - 48x^2 + 140x\)
Setting \(f'(x) = 0\), we have:
\(4x^3 - 48x^2 + 140x = 0\)
Factoring out \(4x\), we get:
\(4x(x^2 - 12x + 35) = 0\)
Simplifying the quadratic factor:
\(x^2 - 12x + 35 = 0\)
Solving this quadratic equation, we find:
\((x - 5)(x - 7) = 0\)
So, \(x = 5\) and \(x = 7\) are the critical points.
Step 2: Evaluate the function at the critical points and endpoints.
\(f(-1) = (-1)^4 - 16(-1)^3 + 70(-1)^2 = 1 + 16 + 70 = 87\)
\(f(5) = (5)^4 - 16(5)^3 + 70(5)^2 = 625 - 4000 + 1750 = -625\)
\(f(6) = (6)^4 - 16(6)^3 + 70(6)^2 = 1296 - 6912 + 2520 = -3096\)
Step 3: Compare the values obtained to find the absolute extreme values.
The function \(f(x) = x^4 - 16x^3 + 70x^2\) has the following values within the given interval:
\(f(-1) = 87\)
\(f(5) = -625\)
\(f(6) = -3096\)
The maximum value is 87, and the minimum value is -3096.

Question 2 Find the particular solution of the following using the method of undetermined coefficients: des dt2 ds ds +8s = 4e2t where t= 0,5 = 0 and dt = 10 dt [15]
The particular solution of the given differential equation using the method of undetermined coefficients is s(t) = (2/9)e^(2t) - (5/9)e^(-4t).
To find the particular solution using the method of undetermined coefficients, we assume a solution of the form s(t) = A*e^(2t) + B*e^(-4t), where A and B are constants to be determined.
Taking the first and second derivatives of s(t), we have:
s'(t) = 2A*e^(2t) - 4B*e^(-4t)
s''(t) = 4A*e^(2t) + 16B*e^(-4t)
Substituting these derivatives back into the original differential equation, we get:
4A*e^(2t) + 16B*e^(-4t) + 8(A*e^(2t) + B*e^(-4t)) = 4e^(2t)
Simplifying the equation, we have:
(12A + 16B)*e^(2t) + (8A - 8B)*e^(-4t) = 4e^(2t)
For the equation to hold for all t, we equate the coefficients of the terms with the same exponential factors:
12A + 16B = 4
8A - 8B = 0
Solving these equations simultaneously, we find A = 2/9 and B = -5/9.
Substituting these values back into the assumed solution, we obtain the particular solution s(t) = (2/9)e^(2t) - (5/9)e^(-4t).

[tex]z=2(r cos(\theta))^{2} +2(rsin\theta))^{2}-4[/tex]
[tex]z=2(r^{2} cos(2\theta))^{2} +2(sin2\theta))^{2}-4[/tex]
[tex]z=2r^2-4[/tex]
The second paraboloid equation [tex]z = 5 - x^2 - y^2[/tex] can be expressed in cylindrical form as:
[tex]z = 5 - (r cos(\theta))^2 - (r sin(\theta))^2[/tex]
[tex]z = 5 - r^2(cos^2(\theta) + sin^2(\theta))[/tex]
[tex]z = 5 - r^2[/tex]
Now, we can determine the limits of integration for the triple integral. The region D is bounded by the two paraboloids and the given limits for x and y.
For x, the limit is 0 to 2 because x ranges from 0 to 2.
For y, the limit is 0 to π/2 because y ranges from 0 to π/2.
The limits for r and θ depend on the region of interest where the two paraboloids intersect. To find this intersection, we set the two paraboloid equations equal to each other:
[tex]2r^2 - 4 = 5 - r^2[/tex]
Simplifying the equation:
[tex]3r^2 = 9[/tex]
Taking the positive square root, we have:
[tex]r = \sqrt{3}[/tex]
Now, we can set up the triple integral:
[tex]V=\int\int\int_{\text{D} f(x, y, z) \, dz\, dr \, d\theta[/tex]
The limits of integration for r are 0 to √3, and for θ are 0 to π/2. The limit for z depends on the equations of the paraboloids, so we need to determine the upper and lower bounds for z within the region D.
The upper bound for z is given by the first paraboloid equation:
[tex]z = 2r^2 - 4[/tex]
The lower bound for z is given by the second paraboloid equation:
[tex]z = 5 - r^2[/tex]
Therefore, the triple integral in cylindrical coordinates that allows us to evaluate the volume of region D is:
[tex]V = \iiint\limits_{\substack{0\leq r \leq 2\\0\leq \theta \leq \pi\\2r^2-4\leq z \leq 5-r^2}} dz \, dr \, d\theta[/tex]

Let T: R2 - R? be a linear transformation defined by (CD) - (22). 18 Is T linear? Why?
based on the preservation of addition and scalar multiplication, we can conclude that the given transformation [tex]T: R^2 - > R?[/tex] defined by T(CD) = (22) + 18 is indeed linear.
What is homogeneous property?
The homogeneous property, also known as homogeneity or scalar multiplication property, is one of the properties that a linear transformation must satisfy. It states that for a linear transformation T and a scalar (real number) k, the transformation of the scalar multiple of a vector is equal to the scalar multiple of the transformation of that vector.
To determine if a linear transformation is linear, it needs to satisfy two conditions:
Preservation of addition: For any vectors u and v in the domain of the transformation T, T(u + v) = T(u) + T(v).
Preservation of scalar multiplication: For any vector u in the domain of T and any scalar c, T(cu) = cT(u).
Let's analyze the given transformation [tex]T: R^2 - > R?[/tex] defined by T(CD) = (22) + 18.
Preservation of addition:
Let's consider two arbitrary vectors u = (a, b) and v = (c, d) in [tex]R^2[/tex].
T(u + v) = T(a + c, b + d) = (22) + 18 = (22) + 18.
Now, let's evaluate T(u) + T(v):
T(u) + T(v) = (22) + 18 + (22) + 18 = (44) + 36.
Since T(u + v) = (22) + 18 = (44) + 36 = T(u) + T(v), the preservation of addition condition is satisfied.
Preservation of scalar multiplication:
Let's consider an arbitrary vector u = (a, b) in [tex]R^2[/tex] and a scalar c.
T(cu) = T(ca, cb) = (22) + 18.
Now, let's evaluate cT(u):
cT(u) = c((22) + 18) = (22) + 18.
Since T(cu) = (22) + 18 = cT(u), the preservation of scalar multiplication condition is satisfied.
Therefore, based on the preservation of addition and scalar multiplication, we can conclude that the given transformation [tex]T: R^2 - > R?[/tex]defined by T(CD) = (22) + 18 is indeed linear.

consider a data set corresponding to readings from a distance sensor: 9, 68, 25, 72, 46, 29, 24, 93, 84, 17 if normalization by decimal scaling is applied to the set, what would be the normalized value of the first reading, 9?
If decimal scaling normalization is applied to the given data set, the normalized value of the first reading, 9, would be 0.09.
To normalize the first reading, 9, we divide it by 100. Therefore, the normalized value of 9 would be 0.09.By applying the same normalization process to each value in the data set, we would obtain the normalized values for all readings. The purpose of normalization is to scale the data so that they fall within a specific range, often between 0 and 1, making it easier to compare and analyze different variables or data sets.

1. Approximate the area between y = h(x) and the x-axis from x = -2 to x = 4 using a right Riemann sum with three equal intervals. v=h(z) 2. Approximate the area between the x-axis and y=g(x) from x=1
To approximate the area between the function y = h(x) and the x-axis from x = -2 to x = 4 using a right Riemann sum with three equal intervals, we first divide the interval [x = -2, x = 4] into three equal subintervals.
The width of each subinterval is Δx = (4 - (-2))/3 = 2.
Next, we evaluate the function h(x) at the right endpoint of each subinterval. Let's denote the right endpoints as x₁, x₂, and x₃. We calculate h(x₁), h(x₂), and h(x₃).
Then, we compute the right Riemann sum using the formula:
Approximate area ≈ Δx * [h(x₁) + h(x₂) + h(x₃)]
By plugging in the calculated values, we can find the numerical approximation for the area between the curve and the x-axis.
To approximate the area between the x-axis and the function y = g(x) from x = 1 to x = b, where b is a given value, we can use a left Riemann sum. Similar to the previous example, we divide the interval [x = 1, x = b] into n equal subintervals, where n is a positive integer.
The width of each subinterval is Δx = (b - 1)/n, and we evaluate the function g(x) at the left endpoint of each subinterval. Let's denote the left endpoints as x₀, x₁, ..., xₙ₋₁. We calculate g(x₀), g(x₁), ..., g(xₙ₋₁).
Then, we compute the left Riemann sum using the formula:
Approximate area ≈ Δx * [g(x₀) + g(x₁) + ... + g(xₙ₋₁)]
By plugging in the calculated values and taking the limit as n approaches infinity, we can obtain a more accurate approximation for the area between the curve and the x-axis.

A gardner is mowing a 20 x 40 yard rectangular pasture using a diagonal pattern.
The complete question may be like:
A gardener is trimming a hedge in a rectangular garden using a diagonal pattern. The garden measures 15 feet by 30 feet. How many total linear feet will the gardener trim if they follow the diagonal pattern to trim all sides of the hedge?
The gardener will trim a total of 90 linear feet when using a diagonal pattern to trim all sides of the hedge in the rectangular garden.
To find the total linear feet the gardener will trim when using a diagonal pattern to trim all sides of the hedge in a rectangular garden, we need to determine the length of the diagonal.
Using the Pythagorean theorem, we can calculate the length of the diagonal:
Diagonal = √(Length^2 + Width^2)
Diagonal = √(15^2 + 30^2)
Diagonal = √(225 + 900)
Diagonal = √1125
Diagonal ≈ 33.54 feet
Since the diagonal pattern follows the perimeter of the rectangular garden, the gardener will trim along the four sides, which add up to twice the sum of the length and width of the garden:
Total Linear Feet = 2 * (Length + Width)
Total Linear Feet = 2 * (15 + 30)
Total Linear Feet = 2 * 45
Total Linear Feet = 90 feet
Therefore, the gardener will trim a total of 90 linear feet when using a diagonal pattern to trim all sides of the hedge in the rectangular garden.

(a) Find the transition matrix from C to B.
b) Find the transition matrix from B to C.
(c) Write p(x) = a + bx + cx
(a) To find the transition matrix from C to B, we need to express the basis vectors of C in terms of the basis vectors of B.
Let's denote the transition matrix from C to B as [T]. We want to find [T] such that [C] = [T][B], where [C] and [B] are the matrices representing the basis vectors C and B, respectively.
The basis vectors of C can be written as:
C = {1, (x - 1), (x - 1)^2}
To express these vectors in terms of the basis vectors of B, we substitute (x - 1) with x in the second and third vectors since (x - 1) can be written as x - 1*1:
C = {1, x, x^2}
Therefore, the transition matrix from C to B is:
[T] = [[1, 0, 0], [0, 1, 0], [0, 0, 1]]
(b) To find the transition matrix from B to C, we need to express the basis vectors of B in terms of the basis vectors of C.
Let's denote the transition matrix from B to C as [S]. We want to find [S] such that [B] = [S][C], where [B] and [C] are the matrices representing the basis vectors B and C, respectively.
The basis vectors of B can be written as:
B = {1, x, x^2}
To express these vectors in terms of the basis vectors of C, we substitute x with (x - 1) in the second and third vectors:
B = {1, (x - 1), (x - 1)^2}
Therefore, the transition matrix from B to C is:
[S] = [[1, 0, 0], [0, 1, -2], [0, 0, 1]]
(c) Given p(x) = a + bx + cx^2, we can express this polynomial in terms of the basis vectors of C by multiplying the coefficients with the corresponding basis vectors:
p(x) = a(1) + b(x - 1) + c(x - 1)^2
Expanding and simplifying the equation:
p(x) = a + bx - b + cx^2 - 2cx + c
Collecting like terms:
p(x) = (a - b + c) + bx - 2cx + cx^2
Therefore, p(x) can be written as p(x) = (a - b + c) + bx - 2cx + cx^2 in terms of the basis vectors of C.

We are given three quadratic functions and we can sketch their graphs using only the vertex and the y-intercept. The equations are: 3. y = x² - 6x + 5, 4. y = x² - 4x - 3, and 5. y = -3x² + 10x - 7.
To sketch the graph of each parabola using only the vertex and the y-intercept, we start by identifying these key points. For the first equation, y = x² - 6x + 5, the vertex can be found using the formula x = -b/(2a), where a = 1 and b = -6. The vertex is at (3, 4), and the y-intercept is at (0, 5). For the second equation, y = x² - 4x - 3, the vertex is at (-b/(2a), f(-b/(2a))), which simplifies to (2, -7). The y-intercept is at (0, -3). For the third equation, y = -3x² + 10x - 7, the vertex can be found in a similar manner as the first equation. The vertex is at (5/6, 101/12), and the y-intercept is at (0, -7). By plotting these key points and drawing the parabolic curves passing through them, we can sketch the graphs of these quadratic functions. To verify the accuracy of the graphs, a graphing calculator can be used.

3 2 26 -0.75 -0.
Using the Fundamental Theorem of Calculus, the integral of (4x - 1) dx can be evaluated as (2x^2 - x) + C, where C is the constant of integration.
To compute the integral (4x - 1) dx in terms of areas, we can relate it to the graph of y = 4x - 1. The integral represents the area under the curve of the function over a given interval. In this case, we want to find the area between the curve and the x-axis.
The graph of y = 4x - 1 is a straight line with a slope of 4 and a y-intercept of -1. The integral of (4x - 1) dx corresponds to the sum of the areas of infinitesimally thin rectangles bounded by the x-axis and the curve.
Each rectangle has a width of dx (an infinitesimally small change in x) and a height of (4x - 1). Summing up the areas of all these rectangles from the lower limit to the upper limit of integration gives us the total area under the curve. Evaluating this integral using the antiderivative of (4x - 1), we obtain the expression (2x^2 - x) + C, where C is the constant of integration.
In conclusion, the integral (4x - 1) dx represents the area between the curve y = 4x - 1 and the x-axis, and using the Fundamental Theorem of Calculus, we can evaluate it as (2x^2 - x) + C, where C is the constant of integration.

The integral ∫9 sec²(8x) dx evaluates to 9/8 tan(8x) + C, where C is the constant of integration.
To solve this integral, we can use the power rule for integration. The derivative of tan(x) is sec²(x), so by applying the power rule in reverse, we can rewrite sec²(8x) as the derivative of tan(8x) multiplied by a constant.
To evaluate the integral ∫9 sec²(8x) dx, we can use the substitution method.
Let's substitute u = 8x, which means du/dx = 8 or du = 8dx. Rearranging the equation, we have dx = du/8.
Now, let's substitute these values into the integral:
∫9 sec²(8x) dx = ∫9 sec²(u) (du/8)
Factoring out the constant 9/8, we get:
(9/8) ∫sec²(u) du
The integral of sec²(u) is tan(u), so we have:
(9/8) tan(u) + C
Substituting back u = 8x, we obtain the final result:

note: in cases where the integral does not have a simple closed-form solution, numerical methods or approximation techniques can be used to compute the value.
to evaluate the integral ∫sin²(x)cos³(x)dx, we can use basic techniques from calculus 2, such as integration by parts and trigonometric identities.
let's proceed step by step:
∫sin²(x)cos³(x)dx
first, we can rewrite sin²(x) as (1/2)(1 - cos(2x)) using the double-angle identity for sine.
∫(1/2)(1 - cos(2x))cos³(x)dx
expanding the expression, we have:
(1/2)∫(cos³(x) - cos⁴(x))dx
next, we can use integration by parts to integrate cos³(x):
let u = cos²(x) and dv = cos(x)dxthen, du = -2cos(x)sin(x)dx and v = sin(x)
∫(cos³(x))dx = ∫u dv = uv - ∫v du = cos²(x)sin(x) - ∫sin(x)(-2cos(x)sin(x))dx
= cos²(x)sin(x) + 2∫sin²(x)cos(x)dx
now, let's substitute this result back into the original integral:
(1/2)∫(cos³(x) - cos⁴(x))dx = (1/2)(cos²(x)sin(x) + 2∫sin²(x)cos(x))dx - (1/2)∫cos⁴(x)dx
simplifying the expression, we get:
