we can say that the congruence `x² ≅ 1 (mod p)` has a solution if and only if `p = 2` or `p ≅ 1 (mod 4)`. Hence, the solution is p = 2 or p ≅ 1 (mod 4).
The given congruence `x² ≅ 1 (mod p)` has a solution if and only if `p = 2` or `p ≅ 1 (mod 4)`.
A solution is a value or set of values that can be substituted into an equation to make it true.
For example, the solution to the equation `x² - 3x + 2 = 0` is `x = 1` or `x = 2`.
Solution for the given congruence: The given congruence is `x² ≅ 1 (mod p)`.
We need to find the value of `p` for which the congruence has a solution.
Now, if the congruence `x² ≅ 1 (mod p)` has a solution, then we can say that `x ≅ ±1 (mod p)` because `1² ≅ 1 (mod p)` and `(-1)² ≅ 1 (mod p)`.
This implies that `p` must divide the difference of `x - 1` and `x + 1` i.e., `(x - 1)(x + 1) ≅ 0 (mod p)`.
This gives us two cases:
Case 1: `p` divides `(x - 1)(x + 1)` i.e., either `p` divides `(x - 1)` or `p` divides `(x + 1)`. In either case, we get `x ≅ ±1 (mod p)`.
Case 2: `p` does not divide `(x - 1)` or `(x + 1)` i.e., `p` and `x - 1` are coprime and `p` and `x + 1` are coprime as well.
Therefore, we can say that `p` divides `(x - 1)(x + 1)` only if `p` divides `(x - 1)` or `(x + 1)` but not both.
Now, `(x - 1)(x + 1) ≅ 0 (mod p)` implies that either `(x - 1) ≅ 0 (mod p)` or `(x + 1) ≅ 0 (mod p)`.
Therefore, we get two cases as follows:
Case A: `(x - 1) ≅ 0 (mod p)` implies that `x ≅ 1 (mod p)` and `x ≅ -1 (mod p)`.
Case B: `(x + 1) ≅ 0 (mod p)` implies that `x ≅ -1 (mod p)` and `x ≅ 1 (mod p)`.
Thus, we can conclude that if the congruence `x² ≅ 1 (mod p)` has a solution, then either `x ≅ 1 (mod p)` and `x ≅ -1 (mod p)`, or `x ≅ -1 (mod p)` and `x ≅ 1 (mod p)`.
Therefore, we can say that `p` must be such that it divides `(x - 1)(x + 1)` but not both `(x - 1)` and `(x + 1)` simultaneously. Hence, we get the following two cases:
Case 1: If `p = 2`, then `(x - 1)(x + 1)` is always divisible by `p`.
Therefore, `x ≅ ±1 (mod p)` for all `x`.
Case 2: If `p ≅ 1 (mod 4)`, then `(x - 1)` and `(x + 1)` are not both divisible by `p`.
Hence, `p` must divide `(x - 1)(x + 1)` for all `x`.

What is derivative?In mathematics, a quantity's instantaneous rate of change with respect to another is referred to as its derivative. Investigating the fluctuating nature of an amount is beneficial.
8-The first partial derivatives of the function f(x, y) = 2 + xy are:
∂f/∂x = y
∂f/∂y = x
The slopes of the tangent planes to the function in the x-direction and the y-direction at the point (1, 0) are:
Slope in the x-direction: ∂f/∂x = y = 0
Slope in the y-direction: ∂f/∂y = x = 1
9-To find the critical points of the function, we need to set the partial derivatives equal to zero:
∂f/∂x = y = 0
∂f/∂y = x = 0
The only critical point is (0, 0).
Using the second derivative test, we can determine the nature of the critical point (0, 0).
The second partial derivatives are:
∂²f/∂x² = 0
∂²f/∂y² = 0
∂²f/∂x∂y = 1
Since the second partial derivatives are all zero, the second derivative test is inconclusive in determining the nature of the critical point.
10-To find the volume of the solid bounded above by the surface z = f(x, y) = xe(-y) and below by the plane region R, we need to evaluate the double integral over the region R:

11- To determine the height of the tree, we can use the tangent of the viewing angle and the distance to the tree:
tan(θ) = height/distance
Given: distance = 400 feet, viewing angle (θ) = 15º
We can rearrange the equation to solve for the height:

The Quotient Rule is a formula used to find the derivative of a function that can be expressed as a quotient of two other functions. The formula is (f'g - fg')/g^2, where f and g are the two functions.
To find the derivative of the given function y = x^6 / (x+7), we can apply the Quotient Rule as follows:
f(x) = x^6, g(x) = x+7
f'(x) = 6x^5, g'(x) = 1
y' = [(6x^5)(x+7) - (x^6)(1)] / (x+7)^2
Simplifying this expression, we get y' = (6x^5 * 7 - x^6) / (x+7)^2
To find the derivative by dividing the expressions first, we can rewrite the function as y = x^6 * (x+7)^(-1), and then use the Power Rule and Product Rule to find the derivative.
y' = [6x^5 * (x+7)^(-1)] + [x^6 * (-1) * (x+7)^(-2) * 1]
Simplifying this expression, we get y' = (6x^5)/(x+7) - (x^6)/(x+7)^2
We can then simplify this expression further to match the result we obtained using the Quotient Rule. In summary, we can use either the Quotient Rule or dividing the expressions first to find the derivative of a function. It is important to check that both methods yield the same result to ensure accuracy.

The given equation represents a circular region in the xy-plane with a radius of 3 units, centered at the origin, and positioned in a horizontal plane at z = -8 in ℝ3.
The equation x^2 + y^2 = 9 represents a circle in the xy-plane with a radius of 3 units. It is centered at the origin (0, 0) since there are no x or y terms with coefficients other than 1.
This means that any point (x, y) on the circle satisfies the equation x^2 + y^2 = 9.

21 Use mathematical induction to show that Σ Coti) = (nti) (nt²)/2 whenever 'n' is a non negative integen J=0
By the principle of mathematical induction, the equation Σ Cot(i) = (n(i) (n^2)/2 holds for all non-negative integers n.
To prove the equation Σ Cot(i) = (n(i) (n^2)/2 using mathematical induction, we need to show that it holds for the base case (n = 0) and then prove the inductive step, assuming it holds for some arbitrary positive integer k and proving it for k+1.
Step 1: Base Case (n = 0)
When n = 0, the left-hand side of the equation becomes Σ Cot(i) = Cot(0) = 1, and the right-hand side becomes (n(0) (n^2)/2 = (0(0) (0^2)/2 = 0.
Thus, the equation holds for n = 0.
Step 2: Inductive Hypothesis
Assume that the equation holds for some positive integer k, i.e., Σ Cot(i) = (k(i) (k^2)/2.
Step 3: Inductive Step
We need to show that the equation holds for k + 1, i.e., Σ Cot(i) = ((k + 1)(i) ((k + 1)^2)/2.
Expanding the right-hand side:
((k + 1)(i) ((k + 1)^2)/2 = (k(i) (k^2)/2 + (k(i) (2k) + (i) (k^2) + (i) (2k) + (i)
= (k(i) (k^2)/2 + (2k(i) (k) + (i) (k^2) + (i) (2k) + (i)
Now, let's look at the left-hand side:
Σ Cot(i) = Cot(0) + Cot(1) + ... + Cot(k) + Cot(k + 1)
Using the inductive hypothesis, we can rewrite this as:
Σ Cot(i) = (k(i) (k^2)/2 + Cot(k + 1)
Combining the two equations, we have:
(k(i) (k^2)/2 + Cot(k + 1) = (k(i) (k^2)/2 + (2k(i) (k) + (i) (k^2) + (i) (2k) + (i)
Simplifying both sides, we get:
(k(i) (k^2)/2 + Cot(k + 1) = (k(i) (k^2)/2 + (2k(i) (k) + (i) (k^2) + (i) (2k) + (i)
The equation holds for k + 1.
By the principle of mathematical induction, the equation Σ Cot(i) = (n(i) (n^2)/2 holds for all non-negative integers n.

To solve for x, we can isolate it by subtracting (-2, -1) from both sides:
3x = (5, 1) - (-2, -1)
3x = (5 + 2, 1 + 1)
3x = (7, 2)

Let F(x,y) = x^2 + y^2 + xy + 3. Find the absolute maximum and minimum values of F on D = {(x,y) x^2+ y^2 ≤ 1}
The function F(x, y) = [tex]x^2 + y^2 + xy + 3[/tex] represents a surface in three-dimensional space. To find the absolute maximum and minimum values of F on the region D, which is defined by the inequality [tex]x^2 + y^2[/tex]≤ 1, we need to consider the critical points and the boundary of D.
First, we find the critical points by taking the partial derivatives of F with respect to x and y, and setting them equal to zero. The partial derivatives are:
∂F/∂x = 2x + y
∂F/∂y = 2y + x
Setting them equal to zero, we have the following equations:
2x + y = 0
2y + x = 0
Solving these equations simultaneously, we get the critical point (x, y) = (0, 0).
Next, we examine the boundary of D, which is the circle [tex]x^2 + y^2[/tex] = 1. Since F is a continuous function, the absolute maximum and minimum values on the boundary can occur at the endpoints or at critical points.
Substituting [tex]x^2 + y^2[/tex] = 1 into F(x, y), we get a new function
G(x) = x² + 1 + x√(1 - x²) + 3. To find the absolute maximum and minimum values of G, we can take its derivative and set it equal to zero. However, finding the exact values analytically is quite complex and involves solving higher-order equations.
To summarize, the absolute maximum and minimum values of F on D = {(x, y) |[tex]x^2 + y^2[/tex]≤ 1} are difficult to determine analytically due to the complexity of the boundary function. Numerical methods or computer approximations would be better suited for finding these values.

Evaluate the integral using the indicated trigonometric substitution. (Use C for the constant of integration.)
x3*sqrt(81 − x2) dx, x = 9 sin(θ)
Therefore, the integral ∫x^3√(81 - x^2) dx, with the trigonometric substitution x = 9sin(θ), simplifies to - 29524.5(1 - x^2/81)^2 + 29524.5(1 - x^2/81)^3 + C.
To evaluate the integral ∫x^3√(81 - x^2) dx using the trigonometric substitution x = 9sin(θ), we need to express the integral in terms of θ and then perform the integration.
First, we substitute x = 9sin(θ) into the expression:
x^3√(81 - x^2) dx = (9sin(θ))^3√(81 - (9sin(θ))^2) d(9sin(θ))
Simplifying the expression:
= 729sin^3(θ)√(81 - 81sin^2(θ)) d(9sin(θ))
= 729sin^3(θ)√(81 - 81sin^2(θ)) * 9cos(θ)dθ
= 6561sin^3(θ)cos(θ)√(81 - 81sin^2(θ)) dθ
Now we can integrate the expression with respect to θ:
∫6561sin^3(θ)cos(θ)√(81 - 81sin^2(θ)) dθ
This integral can be simplified using trigonometric identities. We can rewrite sin^2(θ) as 1 - cos^2(θ):
∫6561sin^3(θ)cos(θ)√(81 - 81(1 - cos^2(θ))) dθ
= ∫6561sin^3(θ)cos(θ)√(81cos^2(θ)) dθ
= ∫6561sin^3(θ)cos(θ) * 9|cos(θ)| dθ
= 59049∫sin^3(θ)|cos(θ)| dθ
Now, we have an odd power of sin(θ) multiplied by the absolute value of cos(θ). We can use the trigonometric identity sin(2θ) = 2sin(θ)cos(θ) to simplify the expression further:
= 59049∫(1 - cos^2(θ))sin(θ)|cos(θ)| dθ
= 59049∫(sin(θ) - sin(θ)cos^2(θ))|cos(θ)| dθ
Now, we can split the integral into two separate integrals:
= 59049∫sin(θ)|cos(θ)| dθ - 59049∫sin(θ)cos^2(θ)|cos(θ)| dθ
Integrating each term separately:
= - 59049∫sin^2(θ)cos(θ) dθ - 59049∫sin(θ)cos^3(θ) dθ
Using the trigonometric identity sin^2(θ) = 1 - cos^2(θ), and substituting u = cos(θ) for each integral, we can simplify further:
= - 59049∫(1 - cos^2(θ))cos(θ) dθ - 59049∫sin(θ)cos^3(θ) dθ
= - 59049∫(u^3 - u^5) du - 59049∫u^3(1 - u^2) du

= - 29524.5(1 - x^2/81)^2 + 29524.5(1 - x^2/81)^3 + C

3. (8 pts.) Renewable energy consumption in the United States (as a percentage of total energy consumption) can be approximated by f(x) = 9.7 ln x 16.5 where x = 15 corresponds to the year 2015. Round
On renewable energy consumption in the United States:
(a) The percentage of renewable energy consumption now is approximately 13.74%.(b) The percentage of renewable energy consumption is predicted to increase by about 0.41% from 2023 to 2024.(c) The percentage of renewable energy consumption is expected to increase by about 0.42% within the next year.(d) The derivative overestimates the actual change.How to determine percentage?(a) First, figure out what "now" is. The problem states that x = 15 corresponds to the year 2015. If currently in 2023, then x = 23, since it's 8 years after 2015. So, evaluate the function f(x) at x = 23:
f(23) = 9.7 × ln(23) - 16.5
Use a calculator for this:
f(23) ≈ 9.7 × 3.13549 - 16.5 = 13.74 (approximately)
So, the percentage of renewable energy consumption now is approximately 13.74%.
(b) Now to predict the percentage change between now (2023) and next year (2024). To do this, compute the difference between f(24) and f(23):
Δf = f(24) - f(23) = (9.7 × ln(24) - 16.5) - (9.7 × ln(23) - 16.5)
Simplifying this gives:
Δf = 9.7 × ln(24) - 9.7 × ln(23) = 9.7 × (ln(24) - ln(23))
Δf ≈ 9.7 × (3.17805 - 3.13549) = 0.41 (approximately)
So, according to the model, the percentage of renewable energy consumption is predicted to increase by about 0.41% from 2023 to 2024.
(c) Now to use a derivative to estimate the change within the next year. The derivative of f(x) = 9.7 × ln(x) - 16.5 is:
f'(x) = 9.7 / x
This gives the rate of change of the percentage at any year x. Evaluate this at x = 23 to estimate the change in the next year:
f'(23) = 9.7 / 23 = 0.42 (approximately)
So, according to the derivative, the percentage of renewable energy consumption is expected to increase by about 0.42% within the next year.
(d) Finally, compare the results from (b) and (c) to see whether the derivative overestimates or underestimates the actual change. The difference is:
Δf - f'(23) = 0.41 - 0.42 = -0.01
Since the derivative's estimate (0.42%) is slightly larger than the model's prediction (0.41%), the derivative overestimates the actual change.

dy = 9e²+7, y(-7)= 0 dz Solve the initial value problem above. (Express your answer in the form y=f(x).)
The solution to the initial value problem is y = 9/2 * e^(2x) + 7x + 49 - 9/2 * e^(-14).
To solve the initial value problem, we need to find the function y(x) that satisfies the given differential equation and initial condition.
The given differential equation is dy/dx = 9e^(2x) + 7.
To solve this, we can integrate both sides of the equation with respect to x:
∫ dy = ∫ (9e^(2x) + 7) dx
Integrating, we get:
y = 9/2 * e^(2x) + 7x + C
where C is the constant of integration.
To find the specific value of C, we use the initial condition y(-7) = 0. Substituting x = -7 and y = 0 into the equation, we can solve for C:
0 = 9/2 * e^(2*(-7)) + 7*(-7) + C
0 = 9/2 * e^(-14) - 49 + C
C = 49 - 9/2 * e^(-14)
Now we have the complete solution:
y = 9/2 * e^(2x) + 7x + 49 - 9/2 * e^(-14)
Therefore, the solution to the initial value problem is y = 9/2 * e^(2x) + 7x + 49 - 9/2 * e^(-14).

Score on last try: 0 of 1 pts. See Details for more. > Next question Get a similar question Find the radius of convergence for n! -xn. 1.3.5... (2n − 1) . n=1 [infinity] X Question Help: Message instructor
The radius of convergence for the series ∑(n=1 to ∞) n! * (-x)^n * (1.3.5... (2n − 1)) is R = ∞, indicating that the series converges for all values of x.
To find the radius of convergence for the series ∑(n=1 to ∞) n! * (-x)^n * (1.3.5... (2n − 1)), we can use the ratio test. The ratio test allows us to determine the range of values for which the series converges.
Let's start by applying the ratio test. The ratio test states that if the limit of the absolute value of the ratio of consecutive terms is less than 1, then the series converges. Mathematically, the ratio test can be expressed as:
lim[n→∞] |(a[n+1] / a[n])| < 1,
where a[n] represents the nth term of the series.
In our case, the nth term is given by a[n] = n! * (-x)^n * (1.3.5... (2n − 1)). Let's calculate the ratio of consecutive terms:
|(a[n+1] / a[n])| = |((n+1)! * (-x)^(n+1) * (1.3.5... (2(n+1) − 1))) / (n! * (-x)^n * (1.3.5... (2n − 1)))|.
Simplifying the expression, we have:
|(a[n+1] / a[n])| = |((n+1) * (-x) * (2(n+1) − 1)) / (1.3.5... (2n − 1))|.
As n approaches infinity, the expression becomes:
lim[n→∞] |(a[n+1] / a[n])| = lim[n→∞] |((n+1) * (-x) * (2(n+1) − 1)) / (1.3.5... (2n − 1))|.
To simplify the expression further, we can focus on the dominant terms. As n approaches infinity, the terms 1.3.5... (2n − 1) behave like (2n)!, while the terms (n+1) * (-x) * (2(n+1) − 1) behave like (2n) * (-x).
Simplifying the expression using the dominant terms, we have:
lim[n→∞] |(a[n+1] / a[n])| = lim[n→∞] |((2n) * (-x)) / ((2n)!)|.
Now, we can apply the ratio test:
lim[n→∞] |(a[n+1] / a[n])| = lim[n→∞] |((2n) * (-x)) / ((2n)!)| < 1.
To find the radius of convergence, we need to determine the range of values for x that satisfy this inequality. However, it is difficult to determine this range explicitly.
Instead, we can use a result from the theory of power series. The radius of convergence, denoted by R, can be calculated using the formula:
R = 1 / lim[n→∞] |(a[n+1] / a[n])|.
In our case, this simplifies to:
R = 1 / lim[n→∞] |((2n) * (-x)) / ((2n)!)|.
Evaluating this limit is challenging, but we can make an observation. The terms (2n) * (-x) / (2n)! tend to zero as n approaches infinity for any finite value of x. This is because the factorial term in the denominator grows much faster than the linear term in the numerator.
Therefore, we can conclude that the radius of convergence for the given series is R = ∞, which means the series converges for all values of x.

Evaluate the following limits: (2 points each) - a. lim 2x3 - 7x 3 b. lim x2 – 7x -8 x+1 (4 + 2) - 16 C. lim h-0 h
The limit of (2x^3 - 7x) as x approaches infinity is infinity. The limit of ((x^2 - 7x - 8) / (x + 1)) as x approaches -1 is -7. The limit of h as h approaches 0 is 0.
What exactly is a limit?In mathematics, the concept of a limit is used to describe the behavior of a function or a sequence as the input values approach a particular value or go towards infinity or negative infinity. The limit represents the value that a function or sequence "approaches" or gets arbitrarily close to as the input values get closer and closer to a given point or as they become extremely large or small.
Formally, the limit of a function f(x) as x approaches a certain value, denoted as lim (x -> a) f(x), is defined as the value that f(x) gets arbitrarily close to as x gets arbitrarily close to a. If the limit exists, it means that the function's values approach a specific value or exhibit a certain behavior at that point.
a. To evaluate the limit lim (2x^3 - 7x) as x approaches infinity, we can consider the highest power of x in the expression, which is x^3. As x becomes larger and larger (approaching infinity), the dominant term in the expression will be 2x^3. The coefficients (-7) and constant terms become relatively insignificant compared to the rapidly growing x^3 term. Therefore, the limit as x approaches infinity is also infinity.
b. To evaluate the limit lim [tex]lim \frac{x^2 - 7x - 8}{x + 1}[/tex] as x approaches -1, we substitute -1 into the expression:
[tex]=\frac{(-1)^2) - 7(-1) - 8}{(-1) + 1} \\=\frac{1 + 7 - 8}{0}[/tex]
This expression results in an indeterminate form of 0/0, which means further simplification is required to determine the limit.
To simplify the expression, we can factor the numerator:
[tex]\frac{(1 - 8)(x + 1)}{(x + 1) }[/tex]
Now, we notice that the factor (x + 1) appears in both the numerator and denominator. We can cancel out this common factor:
(1 - 8) = -7
Therefore, the limit lim [tex]\frac{x^2 - 7x - 8}{x + 1}[/tex] as x approaches -1 is -7.
c. To evaluate the limit lim (h) as h approaches 0, we simply substitute 0 into the expression:
lim (h) = 0
Therefore, the limit is 0.

Suppose a parabola has focus at (-8, 2), opens downward, has a horizontal directrix, and passes through the point (24, 62). The directrix will have equation (Enter the equation of the directrix) The equation of the parabola will be (Enter the equation of the parabola)
The standard equation for a parabola with a focus at (a, b) is given by:$[tex](y - b)^2[/tex] = 4p(x - a)$where p is the distance from the vertex to the focus.
If the parabola opens downward, the vertex is the maximum point and is given by (a, b + p).
If the parabola has a horizontal directrix, then it is parallel to the x-axis and is of the form y = k, where k is the distance from the vertex to the directrix.
Since the focus is at (-8, 2) and the parabola opens downward, the vertex is at (-8, 2 + p).
Also, since the directrix is horizontal, the equation of the directrix is of the form y = k.
To find the value of p, we can use the distance formula between the focus and the point (24, 62):
$p = \frac{1}{4}|[tex](-8 - 24)^2[/tex] + [tex](2 - 62)^2[/tex]| = 40$So the vertex is at (-8, 42) and the equation of the directrix is y = -38.
The equation of the parabola is therefore:
$(y - 42)^2 = -160(x + 8)
$Simplifying: $[tex]y^2[/tex] - 84y + 1764 = -160x - 1280$$[tex]y^2[/tex] - 84y + 3044 = -160x$

Evaluate the line integral R = ∫_c y^2dx+xdy where C is the arc of the parabola x = 4 - y^2 from (-5, -3) to (0,2).
The line integral of the given function, ∫_c y²dx+xdy, along the arc of the parabola x = 4 - y² from (-5, -3) to (0, 2), can be evaluated by parameterizing the curve and then calculating the integral using the parameterization.
To evaluate the line integral, we first need to parameterize the given curve. Since the parabola is defined by x = 4 - y², we can choose y as the parameter. Let's denote y as t, where t varies from -3 to 2. Then, we can express x in terms of t as x = 4 - t².
Next, we differentiate the parameterization to obtain dx/dt = -2t and dy/dt = 1. Now, we substitute these values into the line integral expression: ∫_c y²dx + xdy = ∫_c y²(-2t)dt + (4 - t²)dt.
Now, we integrate with respect to t, using the limits of -3 to 2, since those are the parameter values corresponding to the given endpoints. After integrating, we obtain the value of the line integral.
By evaluating the integral, you will find the numerical result for the line integral along the arc of the parabola x = 4 - y² from (-5, -3) to (0, 2), based on the given function ∫_cy²dx + xdy.

The correlation coefficient measures the strength and direction of the linear relationship between two variables, but it does not differentiate between positive and negative relationships.
The correlation coefficient, often denoted as r, ranges between -1 and 1. A positive value of r indicates a positive linear relationship, while a negative value of r indicates a negative linear relationship. However, the magnitude of the correlation coefficient, regardless of its sign, represents the strength of the relationship.
When the correlation coefficient is close to 1 (either positive or negative), it indicates a strong linear relationship between the variables. Conversely, when the correlation coefficient is close to 0, it suggests a weak linear relationship or no linear relationship at all.
Therefore, the closeness of the correlation coefficient to 1 does not specifically indicate a negative linear relationship. It is the sign of the correlation coefficient that determines the direction (positive or negative), while the magnitude represents the strength.

Use the substitution u = 4x + 3 to find the following indefinite integral. Check your answer by differentiation | - 8x sin (4x + 3) dx s - 8x sin(4x2 + 3) dx = + 0
To find the indefinite integral of -8x sin(4x + 3) dx, we can use the substitution u = 4x + 3. After performing the substitution and integrating, we obtain the antiderivative of -2/4 cos(u) du. We then substitute back u = 4x + 3 to find the final answer. Differentiating the result confirms its correctness.
Let's start by making the substitution u = 4x + 3. We can rewrite the integral as -8x sin(4x + 3) dx = -2 sin(u) du. Now we can integrate -2 sin(u) with respect to u to obtain the antiderivative. The integral of -2 sin(u) du is 2 cos(u) + C, where C is the constant of integration.
Substituting back u = 4x + 3, we have 2 cos(u) + C = 2 cos(4x + 3) + C. This expression represents the antiderivative of -8x sin(4x + 3) dx.
To verify the result, we can differentiate 2 cos(4x + 3) + C with respect to x. Taking the derivative gives -8 sin(4x + 3), which is the original function. Thus, the obtained antiderivative is correct.
Therefore, the indefinite integral of -8x sin(4x + 3) dx is 2 cos(4x + 3) + C, where C is the constant of integration.
