To find the volume of the pyramid with a base in the plane z = -8 and sides formed by the three planes y = 0, y - x = 3, and x + 2y + z = 3, we can use a triple integral. By setting up the appropriate limits of integration and integrating the volume element, we can calculate the volume of the pyramid.

The base of the pyramid lies in the plane z = -8. The sides of the pyramid are formed by the three planes y = 0, y - x = 3, and x + 2y + z = 3.

To find the volume of the pyramid, we need to integrate the volume element dV over the region bounded by the given planes. The volume element can be expressed as dV = dz dy dx.

The limits of integration can be determined by finding the intersection points of the planes. By solving the equations of the planes, we find that the intersection points occur at y = -1, x = -4, and z = -8.

The volume of the pyramid can be calculated as follows:

Volume = ∫∫∫ dV

Integrating the volume element over the appropriate limits will give us the volume of the pyramid.

We used the transformations x = rcos(theta), y = rsin(theta) and z = z and integrated over the limits of r, theta and z to find the required value.

We are given the triple integral to find and we have to convert it into cylindrical coordinates. First, let's draw the given solid enclosed by the xy-plane, z=9, and the cylinder x^2 + y^2 = 4.

Now, to convert to cylindrical coordinates, we use the following transformations:x = rcos(theta)y = rsin(theta)z = zFrom the cylinder equation: x^2 + y^2 = 4r^2 = 4 => r = 2.

From the plane equation: z = 9The limits of integration in cylindrical coordinates are r, theta and z. Here, z goes from 0 to 9, theta goes from 0 to 2pi and r goes from 0 to 2 (using the cylinder equation).

Hence, the triple integral becomes:∭ E dV= ∫(from 0 to 9) ∫(from 0 to 2π) ∫(from 0 to 2) r dz dθ drNow integrating, we get:∫(from 0 to 2) r dz = 9r∫(from 0 to 2π) 9r dθ = 18πr∫(from 0 to 2) 18πr dr = 9π r^2.

Therefore, the main answer is:∭ E dV = 9π (2^2 - 0^2) = 36πSo, the triple integral in cylindrical coordinates is 36π.

Hence, this is the required "main answer"

integral in cylindrical coordinates.

The given solid is shown below:Now, to convert to cylindrical coordinates, we use the following transformations:x = rcos(theta)y = rsin(theta)z = zFrom the cylinder equation: x^2 + y^2 = 121r^2 = 121 => r = 11.

From the plane equation: z = xThe limits of integration in cylindrical coordinates are r, theta and z. Here, z goes from 0 to r, theta goes from 0 to 2pi and r goes from 0 to 11 (using the cylinder equation).

Hence, the triple integral becomes:∭ E xdV = ∫(from 0 to 11) ∫(from 0 to 2π) ∫(from 0 to r) rcos(theta) rdz dθ drNow integrating, we get:∫(from 0 to r) rcos(theta) dz = r^2/2 cos(theta)∫(from 0 to 2π) r^2/2 cos(theta) dθ = 0 (as cos(theta) is an odd function)∫(from 0 to 11) 0 dr = 0Therefore, the triple integral is zero. Hence, this is the required "main answer".

In this question, we had to find the triple integral by converting to cylindrical coordinates. We used the transformations x = rcos(theta), y = rsin(theta) and z = z and integrated over the limits of r, theta and z to find the required value.

The optimal quantities of product A and product B are 13 and 8.25, and the optimal prices for product A and product B are 9.5 thousand dollars and 24.75 thousand dollars

Maximum profit that can be obtained from these quantities and prices is 381.875 thousand dollars

Pricing functions for product A is p = 16 - (1/2)x (for 0 ≤ x ≤ 32)

Pricing function for product B is q = 33 - y (for 0 ≤ y ≤ 33)

Cost function for both product is C = 3x + 2y (for all x and y)

Quantities and the prices of the two products that maximize profit. Maximum profit.

We know that profit function (P) is given by: P(x,y) = R(x,y) - C(x,y)  

Where, R(x,y) = Revenue earned from the sale of products x and y.

C(x,y) = Cost incurred to produce products x and y.From the given pricing functions, we can write the Revenue function for each product as follows:

R(x) = x(16 - (1/2)x)R(y) = y(33 - y)

Using the cost function given, we can write the profit function as:

P(x,y) = R(x) + R(y) - C(x,y)P(x,y) = x(16 - (1/2)x) + y(33 - y) - (3x + 2y)P(x,y) = -1/2 x² + 13x - 2y² + 33y

For finding the maximum profit, we need to find the partial derivatives of P(x,y) with respect to x and y, and equate them to zero.

∂P/∂x = -x + 13 = 0  

⇒ x = 13

∂P/∂y = -4y + 33 = 0

⇒ y = 33/4

We need to find the quantities of product A (x) and product B (y), that maximizes the profit function

P(x,y).x = 13 and y = 33/4 satisfy the constraints 0 ≤ x ≤ 32 and 0 ≤ y ≤ 33.

Respective prices of product A and product B can be calculated by substituting the values of x and y into the pricing functions.p = 16 - (1/2)x = 16 - (1/2)(13) = 9.5 thousand dollars (for product A)q = 33 - y = 33 - (33/4) = 24.75 thousand dollars (for product B).

Therefore, the optimal quantities of product A and product B are 13 and 8.25, respectively. And the optimal prices for product A and product B are 9.5 thousand dollars and 24.75 thousand dollars, respectively.

Maximum profit can be calculated by substituting the values of x and y into the profit function P(x,y).P(x,y) = -1/2 x² + 13x - 2y² + 33y

P(13,33/4) = -1/2 (13)² + 13(13) - 2(33/4)² + 33(33/4)

P(13,33/4) = 381.875 thousand dollars.

Hence, the quantities and the prices of the two products that maximize profit are:

Product A: Quantity = 13 and Price = 9.5 thousand dollars

Product B: Quantity = 8.25 and Price = 24.75 thousand dollars.

Therefore, Maximum profit that can be obtained from these quantities and prices is 381.875 thousand dollars.

Given, we have to find the volume of the solid created by revolving y = x² around the x-axis from x = 0 to x = 1.

To find the volume of the solid, we can use the Disk/Washer method.

The volume of a solid generated by revolving about the x-axis the region bounded by the graph of the continuous function $f(x) \ge 0$, the x-axis, and the vertical lines $x = a$ and $x = b$ is given by $\int_a^b \pi[f(x)]^2dx$.

The disk/washer method states that the volume of a solid generated by revolving about the x-axis the region bounded by the graph of the continuous function $f(x) \ge 0$, the x-axis, and the vertical lines $x = a$ and $x = b$ is given by $\int_a^b \pi[f(x)]^2dx$.Given $y = x^2$ is rotated about the x-axis from $x = 0$ to $x = 1$. So we have $f(x) = x^2$ and the limits of integration are $a = 0$ and $b = 1$.

Therefore, the volume of the solid is:$$\begin{aligned}V &= \pi \int_{0}^{1} (x^2)^2 dx \\&= \pi \int_{0}^{1} x^4 dx \\&= \pi \left[\frac{x^5}{5}\right]_{0}^{1} \\&= \pi \cdot \frac{1}{5} \\&= \boxed{\frac{\pi}{5}}\end{aligned}$$

To find the Taylor series expansion of \( f(x) \) about \( c = 0 \), we need to compute the derivatives of \( f(x) \) and evaluate them at \( x = 0 \).

The first few derivatives of \( f(x) \) are:
\( f'(x) = \frac{-1}{(x+5)^2} \),
\( f''(x) = \frac{2}{(x+5)^3} \),
\( f'''(x) = \frac{-6}{(x+5)^4} \),
\( f''''(x) = \frac{24}{(x+5)^5} \),
...

The Taylor series expansion is given by:
\( f(x) = f(0) + f'(0)x + \frac{f''(0)}{2!}x^2 + \frac{f'''(0)}{3!}x^3 + \frac{f''''(0)}{4!}x^4 + \ldots \).

Substituting the derivatives evaluated at \( x = 0 \), we have:
\( f(x) = 1 - x + x^2 - x^3 + x^4 - \ldots \).

The interval of convergence can be determined by applying the ratio test. By evaluating the ratio \( \frac{a_{n+1}}{a_n} \), where \( a_n \) represents the coefficients of the series, we find that the series converges for \( -1 < x < 1 \).

The given continuous time system, y(t) = [cos(3t)]x(t), is memoryless, time-invariant, linear, causal, and stable.

1. Memoryless: A system is memoryless if the output at any given time depends only on the input at that same time. In this case, the output y(t) depends solely on the input x(t) at the same time t. Therefore, the system is memoryless.

2. Time Invariant: A system is time-invariant if a time shift in the input results in the same time shift in the output. In the given system, if we delay the input x(t) by a certain amount, the output y(t) will also be delayed by the same amount. Hence, the system is time-invariant.

3. Linear: A system is linear if it satisfies the properties of superposition and scaling. For the given system, it can be observed that it satisfies both properties. The cosine function is a linear function, and the input x(t) is scaled by the cosine function, resulting in a linear relationship between the input and output. Therefore, the system is linear.

4. Causal: A system is causal if the output depends only on the past and present values of the input, but not on future values. In the given system, the output y(t) is determined solely by the input x(t) at the same or previous times. Hence, the system is causal.

5. Stable: A system is stable if the output remains bounded for any bounded input. In the given system, the cosine function is bounded, and multiplying it by the input x(t) does not introduce any instability. Therefore, the system is stable.

Only one line exists that passes through the given point and is parallel to the given line.

To find the number of lines that pass through a given point and are parallel to a given line, we need to understand the concept of parallel lines. Two lines are considered parallel if they never intersect, meaning they have the same slope..

To determine the slope of the given line, we can use the formula:

slope = (change in y)/(change in x).

Once we have the slope of the given line, we can use this slope to find the equation of a line passing through the given point.

The equation of a line can be written in the form y = mx + b, where m represents the slope and b represents the y-intercept. Since the line we are looking for is parallel to the given line, it will have the same slope.

We substitute the given point's coordinates into the equation and solve for b, the y-intercept.

Finally, we can write the equation of the line passing through the given point and parallel to the given line. There is only one line that satisfies these conditions.

In summary, only one line exists that passes through the given point and is parallel to the given line.

When given a line and a point not on the line, there is only one line that can be drawn through the point and be parallel to the given line. This line has the same slope as the given line.

When given a line and a point not on the line, there is exactly one line that can be drawn through the given point and be parallel to the given line. This is due to the definition of parallel lines, which states that parallel lines never intersect and have the same slope.

To visualize this, imagine a line and a point not on the line. Now, draw a line through the given point in any direction. This line will intersect the given line at some point, which means it is not parallel to the given line.

However, if we adjust the slope of the line passing through the point, we can make it parallel to the given line. By finding the slope of the given line and using it as the slope of the line passing through the point, we ensure that both lines have the same slope and are therefore parallel.

Day 3: 9,096 / 2 = 4,548 L

Day 4: 4,548 / 2 = 2,274 L

Day 5: 2,274 / 2 = 1,137 L

Day 6: 1,137 / 2 = 568.5 L (approximated to the nearest whole number as needed)

Day 7: 568.5 / 2 = 284.25 L (approximated to the nearest whole number as needed)

Day 8: 284.25 / 2 = 142.125 L (approximated to the nearest whole number as needed)

Day 9: 142.125 / 2 = 71.0625 L (approximated to the nearest whole number as needed)

Day 10: 71.0625 / 2 = 35.53125 L (approximated to the nearest whole number as needed)

Day 11: 35.53125 / 2 = 17.765625 L (approximated to the nearest whole number as needed)

Therefore, approximately 18 L of water is left in the tank after 11 days.\

The first set of digits (five numbers) in a National Drug Code represent:

Select one:

a. The product strength and dosage form

b. The cost

c. The manufacturer

d. The pack size

(a) To find the probability that all 10 trustworthy individuals pass the polygraph test,

we can use the binomial probability formula:

P(X = 10) = C(10, 10) * (0.15)^10 * (1 - 0.15)^(10 - 10)

Calculating the values:

C(10, 10) = 1 (since choosing all 10 out of 10 is only one possibility)

(0.15)^10 ≈ 0.0000000778

(1 - 0.15)^(10 - 10) = 1 (anything raised to the power of 0 is 1)

P(X = 10) ≈ 1 * 0.0000000778 * 1 ≈ 0.0000000778

The probability that all 10 trustworthy individuals pass the polygraph test is approximately 0.0000000778.

(b) To find the probability that more than 2 trustworthy individuals fail the test, we need to calculate the probability of exactly 0, 1, and 2 individuals failing and subtract it from 1 (to find the complementary probability).

P(more than 2 fail, even though all are trustworthy) = 1 - P(X = 0) - P(X = 1) - P(X = 2)

Using the binomial probability formula:

P(X = 0) = C(10, 0) * (0.15)^0 * (1 - 0.15)^(10 - 0)

P(X = 1) = C(10, 1) * (0.15)^1 * (1 - 0.15)^(10 - 1)

P(X = 2) = C(10, 2) * (0.15)^2 * (1 - 0.15)^(10 - 2)

Calculating the values:

C(10, 0) = 1

C(10, 1) = 10

C(10, 2) = 45

(0.15)^0 = 1

(0.15)^1 = 0.15

(0.15)^2 ≈ 0.0225

(1 - 0.15)^(10 - 0) = 0.85^10 ≈ 0.1967

(1 - 0.15)^(10 - 1) = 0.85^9 ≈ 0.2209

(1 - 0.15)^(10 - 2) = 0.85^8 ≈ 0.2476

P(more than 2 fail, even though all are trustworthy) = 1 - 1 * 0.1967 - 10 * 0.15 * 0.2209 - 45 * 0.0225 * 0.2476 ≈ 0.0004

The probability that more than 2 trustworthy individuals fail the polygraph test, even though all are trustworthy, is approximately 0.0004.

(c) The mean (expected value) of a binomial distribution is given by μ = np, where n is the number of trials (400 agents tested) and p is the probability of success (the probability of failing for a trustworthy agent, which is 0.15).

Mean = μ = np = 400 * 0.15 = 60

The standard deviation of a binomial distribution is given by σ = sqrt(np(1-p)).

Standard deviation = σ = sqrt(400 * 0.15 * (1 - 0.15)) ≈ 4

To determine whether there is enough evidence to reject the null hypothesis, we need to compare the computed test statistic to the critical value.

In this case, the computed test statistic is 2.50 and the critical value is 2.33. If the computed test statistic falls in the rejection region beyond the critical value, we can reject the null hypothesis. Conversely, if the computed test statistic falls within the non-rejection region, we fail to reject the null hypothesis.In this scenario, since the computed test statistic (2.50) is greater than the critical value (2.33), it falls in the rejection region. This means that the observed data is unlikely to occur if the null hypothesis were true.

Therefore, based on the given information, there is enough evidence for the emergency room nurse to reject the null hypothesis. This suggests that there is sufficient evidence to support the claim that the average number of cases of upper respiratory infections per day at the hospital is over 21 cases.

There is enough evidence to reject the null hypothesis in this case because the computed test statistic (2.50) is higher than the critical value (2.33). This suggests the average number of daily respiratory infections exceeds 21, providing substantial evidence against the null hypothesis.

Yes, there is enough evidence for the emergency room nurse to reject the null hypothesis. The null hypothesis is typically a claim of no difference or no effect. In this case, the null hypothesis would be an average of 21 upper respiratory infections per day. The test statistic computed (2.50) exceeds the critical value (2.33). This suggests that the average daily cases indeed exceed 21, hence providing enough evidence to reject the null hypothesis.

It's crucial to understand that when the test statistic is larger than the critical value, we reject the null hypothesis because the observed sample is inconsistent with the null hypothesis. The statistical test indicated a significant difference, upheld by the test statistic value of 2.50. The significance level (alpha) of 0.05 is a commonly used threshold for significance in scientific studies. In this context, the finding suggests that the increase in respiratory infection cases is statistically significant, and the null hypothesis can be rejected.

The vectors u = (2, -1, 0, 3), v = (1, 2, 5, -1), and w = (7, -1, 5, 8) form a linearly independent set.

To determine if the vectors u, v, and w are linearly dependent or independent, we need to check if there exists a non-trivial linear combination of these vectors that equals the zero vector (0, 0, 0, 0).

Let's assume that there exist scalars a, b, and c such that a*u + b*v + c*w = 0. This equation can be expressed as:

a*(2, -1, 0, 3) + b*(1, 2, 5, -1) + c*(7, -1, 5, 8) = (0, 0, 0, 0).

Expanding this equation gives us:

(2a + b + 7c, -a + 2b - c, 5b + 5c, 3a - b + 8c) = (0, 0, 0, 0).

From this system of equations, we can see that each component must be equal to zero individually:

2a + b + 7c = 0,

-a + 2b - c = 0,

5b + 5c = 0,

3a - b + 8c = 0.

Solving this system of equations, we find that a = 0, b = 0, and c = 0. This means that the only way for the linear combination to equal the zero vector is when all the scalars are zero.

Since there is no non-trivial solution to the equation, the vectors u, v, and w form a linearly independent set. In other words, none of the vectors can be expressed as a linear combination of the others.

The inverse of the function f(x) = -x+3 is [tex]f^{-1}[/tex](x) = 3 - x .The graph of the function and its inverse are symmetric about the line y=x.

To find the inverse of a function, we need to interchange the roles of x and y and solve for y.

For the function f(x) = -x + 3, let's find its inverse:

Step 1: Replace f(x) with y: y = -x + 3.

Step 2: Interchange x and y: x = -y + 3.

Step 3: Solve for y: y = -x + 3.

Thus, the inverse of f(x) is [tex]f^{-1}[/tex](x) = -x + 3.

To graph the function and its inverse, we plot the points on a coordinate plane:

For the function f(x) = -x + 3, we can choose some values of x, calculate the corresponding y values, and plot the points. For example, when x = 0, y = -0 + 3 = 3. When x = 1, y = -1 + 3 = 2. When x = 2, y = -2 + 3 = 1. We can continue this process to get more points.

For the inverse function [tex]f^{-1}[/tex](x) = -x + 3, we can follow the same process. For example, when x = 0, y = -0 + 3 = 3. When x = 1, y = -1 + 3 = 2. When x = 2, y = -2 + 3 = 1.

Plotting the points for both functions on the same graph, we can see that they are reflections of each other across the line y = x, which is the line of symmetry.

If the p-value is less than or equal to 0.05, we can say that there is enough evidence to support the alternative hypothesis. In other words, there is enough evidence to support the statement that the proportion of students who use a lab on campus is greater than 0.50.

Performing the hypothesis testFor the hypothesis test, it is necessary to determine the null hypothesis and alternative hypothesis. The null hypothesis is generally the hypothesis that is tested against. It states that the sample statistics are similar to the population statistics.

In contrast, the alternative hypothesis is the hypothesis that is tested for. It states that the sample statistics are different from the population statistics, and the differences are not due to chance.The null and alternative hypothesis are as follows:Null hypothesis: p = 0.50Alternative hypothesis: p > 0.50

The p-value is the probability of observing the sample statistics that are as extreme or more extreme than the sample statistics observed, given that the null hypothesis is true. The p-value is used to determine whether the null hypothesis should be rejected or not.

In hypothesis testing, if the p-value is less than or equal to the significance level, the null hypothesis is rejected, and the alternative hypothesis is accepted. Based on this significance level, if the p-value is less than or equal to 0.05, we reject the null hypothesis and accept the alternative hypothesis.

The student made an error in writing the explicit formula for the given sequence. The correct explicit formula for the given sequence is `an = 3n - 2`. So, the student's error was in adding 1 to the formula, instead of subtracting 2.

Explanation: The given sequence is 1, 4, 7, 10, ... This is an arithmetic sequence with a common difference of 3.

To find the explicit formula for an arithmetic sequence, we use the formula `an = a1 + (n-1)d`, where an is the nth term of the sequence, a1 is the first term of the sequence, n is the position of the term, and d is the common difference.

In the given sequence, the first term is a1 = 1 and the common difference is d = 3. Therefore, the explicit formula for the sequence is `an = 1 + (n-1)3 = 3n - 2`. The student wrote the formula as `an = 3n + 1`. This formula does not give the correct terms of the sequence.

For example, using this formula, the first term of the sequence would be `a1 = 3(1) + 1 = 4`, which is incorrect. Therefore, the student's error was in adding 1 to the formula, instead of subtracting 2.

The derivative of f(x) is -4x + 10. When we evaluate f'(3), we substitute x = 3 into the derivative expression and simplify to obtain f'(3) = -2. The derivative represents the rate of change of the function at a specific point, and in this case, it indicates that the slope of the tangent line to the graph of f(x) at x = 3 is -2.

The value of f ′(3) is -8. After simplifying f ′(x), it is determined to be -4x + 10.

The given function f(x) = (x^2 - 16) / ([tex]x^2 + 16[/tex]) simplifies to f(x) = 1 / ([tex]x^2 + 16[/tex]).

To analyze the given function f(x) = [tex](x^2 - 16) / (x^2 + 16),[/tex] we will simplify the expression and perform further calculations:

First, let's factor the numerator and denominator to simplify the expression:

f(x) =[tex](x^2 - 16) / (x^2 + 16),[/tex]

The numerator can be factored as the difference of squares:

[tex]x^2 - 16[/tex]= (x + 4)(x - 4)

The denominator is already in its simplest form.

Now we can rewrite the function as:

f(x) = [(x + 4)(x - 4)] / ([tex]x^2 + 16[/tex])

Next, we notice that (x + 4)(x - 4) appears in both the numerator and denominator. Therefore, we can cancel out this common factor:

f(x) = (x + 4)(x - 4) / ([tex]x^2 + 16[/tex]) ÷ (x + 4)(x - 4)

(x + 4)(x - 4) in the numerator and denominator cancels out, resulting in:

f(x) = 1 / ([tex]x^2 + 16[/tex])

Now we have the simplified form of the function f(x) as f(x) = 1 / ([tex]x^2 + 16[/tex]).

To summarize, the given function f(x) simplifies to f(x) = 1 / ([tex]x^2 + 16[/tex]) after factoring and canceling out the common terms.

\[v = u \cdot \frac{2\sin\theta\cos(\theta)}{\cos(2\theta)}\]

We have expressions for \(\overline{u-i v}\) and \(v\) in terms of \(u\) and \(\theta\). However, it seems that the equation is cut off and incomplete.

To solve this problem, we'll start by simplifying the expression for \(\overline{u-i v}\):

\[\overline{u-i v}=(1+z)(1-i² z²)\]

First, let's expand the expression \(1-i² z²\):

\[1-i² z² = 1 - i²(\cos² \theta + i² \sin² \theta)\]

Since \(i² = -1\), we can simplify further:

\[1 - i² z² = 1 - (-1)(\cos² \theta + i² \sin²\theta) = 1 + \cos² \theta - i²\sin² \theta\]

Again, since \(i² = -1\), we have:

\[1 + \cos² \theta - i² \sin² \theta = 1 + \cos² \theta + \sin²\theta\]

Since \(\cos² \theta + \sin² \theta = 1\), the above expression simplifies to:

\[1 + \cos² \theta + \sin² \theta = 2\]

Now, let's substitute this result back into the expression for \(\overline{u-i v}\):

\[\overline{u-i v}=(1+z)(1-i² z²) = (1 + z) \cdot 2 = 2 + 2z\]

Next, let's substitute the expression for \(v\) into the equation \(v = u \tan\left(\frac{3\theta}{2}\right)\):

\[v = u \tan\left(\frac{3\theta}{2}\right)\]

\[u \tan\left(\frac{3\theta}{2}\right) = u \cdot \frac{\sin\left(\frac{3\theta}{2}\right)}{\cos\left(\frac{3\theta}{2}\right)}\]

Since \(v = u \tan\left(\frac{3\theta}{2}\right)\), we have:

\[v = u \cdot \frac{\sin\left(\frac{3\theta}{2}\right)}{\cos\left(\frac{3\theta}{2}\right)}\]

We can rewrite \(\frac{3\theta}{2}\) as \(\frac{\theta}{2} + \frac{\theta}{2} + \theta\):

\[v = u \cdot \frac{\sin\left(\frac{\theta}{2} + \frac{\theta}{2} + \theta\right)}{\cos\left(\frac{\theta}{2} + \frac{\theta}{2} + \theta\right)}\]

Using the angle addition formula for sine and cosine, we can simplify this expression:

\[v = u \cdot \frac{\sin\left(\frac{\theta}{2} + \frac{\theta}{2}\right)\cos(\theta) + \cos\left(\frac{\theta}{2} + \frac{\theta}{2}\right)\sin(\theta)}{\cos\left(\frac{\theta}{2} + \frac{\theta}{2}\right)\cos(\theta) - \sin\left(\frac{\theta}{2} + \frac{\theta}{2}\right)\sin(\theta)}\]

Since \(\sin\left(\frac{\theta}{2} + \frac{\theta}{2}\right) = \sin\theta\) and \(\cos

\left(\frac{\theta}{2} + \frac{\theta}{2}\right) = \cos\theta\), the expression becomes:

\[v = u \cdot \frac{\sin\theta\cos(\theta) + \cos\theta\sin(\theta)}{\cos\theta\cos(\theta) - \sin\theta\sin(\theta)}\]

Simplifying further:

\[v = u \cdot \frac{2\sin\theta\cos(\theta)}{\cos²\theta - \sin²\theta}\]

Using the trigonometric identity \(\cos²\theta - \sin²\theta = \cos(2\theta)\), we can rewrite this expression as:

\[v = u \cdot \frac{2\sin\theta\cos(\theta)}{\cos(2\theta)}\]

Now, we have expressions for \(\overline{u-i v}\) and \(v\) in terms of \(u\) and \(\theta\). However, it seems that the equation is cut off and incomplete. If you provide the rest of the equation or clarify what you would like to find, I can assist you further.
