Given that cos(A) = -1 with A in Quadrant III and sin(B) = 5 with B in Quadrant II, we need to find sin(A - B). The value of sin(A - B) can be determined by using the trigonometric identity sin(A - B) = sin(A)cos(B) - cos(A)sin(B). Substituting the known values, sin(A - B) can be calculated.

To find sin(A - B), we can use the trigonometric identity sin(A - B) = sin(A)cos(B) - cos(A)sin(B). From the given information, we have cos(A) = -1 and sin(B) = 5. Let's substitute these values into the identity:

sin(A - B) = sin(A)cos(B) - cos(A)sin(B)

Since cos(A) = -1, we have:

sin(A - B) = sin(A)cos(B) - (-1)sin(B)

Now, we need to determine the values of sin(A) and cos(B) in order to calculate sin(A - B). However, we don't have the given values for sin(A) or cos(B) in the problem statement. Without these values, it is not possible to provide an exact answer for sin(A - B).

Therefore, without the specific values for sin(A) and cos(B), we cannot determine the exact value of sin(A - B) as a fraction of 17.

To set up the integral using the cylindrical shell method, we need to consider infinitesimally thin cylindrical shells parallel to the axis of rotation. Let's assume we are revolving the region R about the x-axis.

The height of each cylindrical shell will be given by the difference between the functions y = 5 - r and y = x - 1. To find the bounds of integration, we need to determine the x-values at which these two functions intersect.

Setting 5 - r = x - 1, we can solve for x:

5 - r = x - 1

x = r + 4

So, the bounds of integration for x will be from r + 4 to some value x = a, where a is the x-value at which the two functions intersect. We'll determine this value later.

The radius of each cylindrical shell will be x, as the shells are parallel to the x-axis.

The height of each cylindrical shell is the difference between the functions, so h = (5 - r) - (x - 1) = 6 - x + r.

The circumference of each cylindrical shell is given by 2πx.

Therefore, the volume of each cylindrical shell is given by V = 2πx(6 - x + r).

To find the total volume, we need to integrate this expression over the range of x from r + 4 to a:

V_total = ∫[r + 4, a] 2πx(6 - x + r) dx

Now, we need to determine the value of a. To find this, we set the two functions equal to each other:

5 - r = x - 1

x = r + 4

So, a = r + 4.

Therefore, the integral representing the volume of the solid formed by revolving the region R about the x-axis using the cylindrical shell method is:

V_total = ∫[r + 4, r + 4] 2πx(6 - x + r) dx

However, since the range of integration is from r + 4 to r + 4, the integral evaluates to zero, and the volume of the solid is zero.

The depth of the water in the tank is changing at a rate of approximately 1.38 meters per second when the radius of the top of the water is 10 meters.

We can use related rates to solve this problem. We are given that the rate of filling the tank is 12 m^3/s. The tank is in the shape of a cone, with a base radius of 26 meters and a height of 8 meters. We need to find the rate of change of the depth of the water when the radius of the top of the water is 10 meters.

Using similar triangles, we can set up the following relationship between the radius of the top of the water (r) and the depth of the water (h):

[tex]r/h = 26/8[/tex]

Taking the derivative of both sides with respect to time, we get:

[tex](dr/dt * h - r * dh/dt) / h^2 = 0[/tex]

Simplifying, we find:

[tex]dr/dt = (r * dh/dt) / h[/tex]

Substituting the given values (r = 10 m and h = 8 m), and solving for dh/dt, we get:

[tex]dh/dt = (dr/dt * h) / r[/tex]

Substituting the rate of filling the tank (dr/dt = 12 m^3/s), we find:

[tex]dh/dt = (12 * 8) / 10 = 9.6 m/s[/tex]

Therefore, the depth of the water in the tank is changing at a rate of approximately 1.38 meters per second when the radius of the top of the water is 10 meters.

In summary:

- The major axis has end points (-2, 0) and (2, 0).

- The minor axis has end points (0, -7) and (0, 7).

- This ellipse does not have real foci.

The equation of the ellipse in standard form is:

(x^2/4) + (y^2/49) = 1

In this form, the major axis is along the x-axis, and the minor axis is along the y-axis.

To identify the end points of the major and minor axes, we need to find the values of a and b, which are the lengths of the semi-major and semi-minor axes, respectively.

For this ellipse, a = 2 and b = 7 (square root of 49).

Therefore, the end points of the major axis are (-2, 0) and (2, 0), and the end points of the minor axis are (0, -7) and (0, 7).

To find the foci of the ellipse, we can calculate c using the formula:

c = sqrt(a^2 - b^2)

In this case, c = sqrt(4 - 49) = sqrt(-45).

Since the value under the square root is negative, it means that this ellipse does not have real foci.

True. f'(x) < 0 when x < c then f(x) is decreasing when x < c.

If the derivative of a function f(x) is negative (f'(x) < 0) for all x values less than a constant c, then it implies that the function is decreasing in the interval (−∞, c).

This is because the derivative represents the rate of change of the function, and a negative derivative indicates a decreasing slope. Thus, when x < c, the function is experiencing a decreasing trend.

However, it is important to note that this statement holds true for continuous functions and assumes that f'(x) is defined and continuous in the interval (−∞, c).

There is no specific value of ‘a’ that will determine the absolute maximum of g(x) within the interval (0,5). The maximum will occur either at x = 0 or x = 5, depending on the specific value of ‘a’ chosen.

To find the value of ‘a’ for which the function g(x) = x * e^(a-1) attains its absolute maximum on the interval (0,5), we need to analyze the behavior of the function and determine the critical points.

First, let’s take the derivative of g(x) with respect to x:

G’(x) = e^(a-1) + x * e^(a-1)

To find the critical points, we set g’(x) equal to zero and solve for x:

E^(a-1) + x * e^(a-1) = 0

Factoring out e^(a-1), we have:

E^(a-1) * (1 + x) = 0

Since e^(a-1) is always positive, the only way for the expression to be zero is when (1 + x) = 0. Solving for x, we find:

X = -1

However, the interval given is (0,5), and -1 is outside that interval. Therefore, there are no critical points within the interval (0,5).

This means that the function g(x) = x * e^(a-1) does not have any maximum or minimum points within the interval. Instead, its behavior depends on the value of ‘a’. The absolute maximum will occur at one of the endpoints of the interval, either at x = 0 or x = 5.

What is Integration?

Integration is a fundamental concept in calculus that involves finding the area under a curve or the accumulation of a quantity over a given interval.

To evaluate the indefinite integral of ∫(sqrt(x) + 1)dx, we will proceed by answering the following parts:

(a) Using u = sqrt(x) + 1, what is du?

To find du, we need to differentiate u with respect to x.

Let's differentiate u = sqrt(x) + 1:

du/dx = d/dx(sqrt(x) + 1)

Using the power rule of differentiation, we get:

du/dx = (1/2)x^(-1/2) + 0

Simplifying, we have:

du/dx = (1/2)x^(-1/2)

(b) What is the new integral in terms of u only?

Now that we have found du/dx, we can rewrite the original integral using u instead of x:

∫(sqrt(x) + 1)dx = ∫u du

The new integral in terms of u only is ∫u du.

(c) Evaluate the new integral.

To evaluate the new integral, we can integrate u with respect to itself:

∫u du = (1/2)u^2 + C

where C is the constant of integration.

We can observe that each term in the series can be written as 5n + 2 = n + 5 - 3 = 5(n + 1) - 3.

Now, let's rewrite the series using this pattern:

Σ (5n+2) = Σ (5(n + 1) - 3)

We can split this series into two separate series:

Σ (5(n + 1)) - Σ 3

The first series can be simplified using the formula for the sum of an arithmetic series:

Σ (5(n + 1)) = 5 Σ (n + 1)

Using the formula for the sum of the first n natural numbers, Σ n = (n/2)(n + 1), we have:

[tex]5 Σ (n + 1) = 5 (Σ n + Σ 1)= 5 ([(n/2)(n + 1)] + [1 + 1 + 1 + ...])= 5 [(n/2)(n + 1) + n]= 5 [(n/2)(n + 1) + 2n]= 5 [(n^2 + 3n)/2][/tex]

Now, let's simplify the second series:

Σ 3 = 3 + 3 + 3 + ...

Since the value of 3 is constant, the sum of this series is infinite.

Putting it all together, we have:

Σ (5n+2) = Σ (5(n + 1)) - Σ 3

= 5 [(n^2 + 3n)/2] - (∞)

Since the second series Σ 3 is infinite, we cannot subtract it from the first series. Therefore, the sum of the series Σ (5n+2) is undefined or infinite

B is equal to arcsin((sin(40°) * y) / (2|A|)) in terms of A, D, and E.

The law of sines specifies how many sides there are in a triangle and how their individual sine angles are equal. The sine law, sine rule, and sine formula are additional names for the sine law. The side or unknown angle of an oblique triangle is found using the law of sine.

To determine the value of B in terms of A, D, and E, we can use the law of sines in triangle ABC. The law of sines states that in any triangle ABC with sides a, b, and c opposite angles A, B, and C, respectively:

sin(A) / a = sin(B) / b = sin(C) / c

In our given triangle, we know the following information:

- |BC| = 5 (magnitude of segment BC)

- |CD| = 8 (magnitude of segment CD)

- Angle C = 35° (angle formed by C and D)

- Angle A = 40° (angle formed by A and E)

- |AE| = 2|A| (magnitude of segment AE is twice the magnitude of segment A)

Let's denote |AB| as x (magnitude of segment AB) and |BE| as y (magnitude of segment BE). Based on the information given, we can set up the following equations:

sin(A) / |AE| = sin(B) / |BE|

sin(40°) / (2|A|) = sin(B) / y    ...equation 1

sin(B) / |BC| = sin(C) / |CD|

sin(B) / 5 = sin(35°) / 8

sin(B) = (5/8) * sin(35°)

B = arcsin((5/8) * sin(35°))    ...equation 2

Now, let's substitute equation 2 into equation 1 to solve for B in terms of A, D, and E:

sin(40°) / (2|A|) = sin(arcsin((5/8) * sin(35°))) / y

sin(40°) / (2|A|) = (5/8) * sin(35°) / y

B = arcsin((5/8) * sin(35°)) = arcsin((sin(40°) * y) / (2|A|))

Therefore, B is equal to arcsin((sin(40°) * y) / (2|A|)) in terms of A, D, and E.

To estimate the percentage error in computing the surface area of a cube, we can use differentials.

Let's denote the edge length of the cube as x and the error in the measurement as Δx. In this case, x = 20 cm and Δx = 0.2 cm. The surface area of a cube is given by A = 6x^2. Taking the differential of the surface area, we have dA = 12x dx.

Now, we can estimate the percentage error in the surface area by dividing the differential by the original surface area and multiplying by 100: percentage error = (dA / A) * 100 = (12x dx / 6x^2) * 100 = 2(dx / x) * 100. Substituting the values x = 20 cm and Δx = 0.2 cm, we get: percentage error = 2(0.2 cm / 20 cm) * 100 = 2%.

How to find a equation of the tangent line?

To find the equation of a tangent line to a curve at a given point, we typically need to calculate the derivative of the curve and evaluate it at the point of tangency. The derivative of a function represents the rate of change of the function with respect to its independent variable, and this rate of change is equivalent to the slope of the tangent line to the curve at any given point.

To find the tangent plane to the equation [tex]z = 2e^x - 2y[/tex] at the point (4, 8, 2), we need to determine the partial derivatives of the equation with respect to x and y.

Given the equation [tex]z = 2e^x - 2y[/tex],then

[tex]\frac{\delta z}{\delta x} = 2e^x[/tex]

[tex]\frac{\delta z}{\delta y} = -2[/tex]

Now, we can find the values of the partial derivatives at the point (4, 8, 2):

[tex]\frac{\delta z}{\delta x} = 2e^4\\\frac{\delta z}{\delta y} = -2[/tex]

Substituting the values into the point-normal form of a plane equation, we have:

[tex]z - z_0 = (\frac{\delta z}{\delta x })(x - x_0) + (\frac{\delta z}{\delta y })(y- y_0)[/tex]

Plugging in the values:

[tex]z - 2 = (2 * e^4)(x - 4) + (-2)(y - 8)[/tex]

Vector AB = B - A = (0, 2, 3) - (1, 1, 2) = (-1, 1, 1)

Vector AC = C - A = (2, 6, 1) - (1, 1, 2) = (1, 5, -1)

Now, we can take the cross product of AB and AC to find the area:

Cross product: AB × AC = (-1, 1, 1) × (1, 5, -1)

To calculate the cross product, we use the following formula:

(AB × AC) = (i, j, k)

i = (1 * 1) - (5 * 1) = -4

j = (-1 * 1) - (1 * -1) = 0

k = (-1 * 5) - (1 * 1) = -6

Therefore, AB × AC = (-4, 0, -6).

The magnitude of the cross product gives us the area of the parallelogram:

a) The coefficient of determination is also known as R-squared and it measures the proportion of the variance in the dependent variable (outcome variable) that is explained by the independent variable (predictor variable) in a linear regression model.

b) The coefficient of determination (R-squared) tells us how much of the variation in the outcome variable is explained by the least squares regression line. Specifically, R-squared ranges from 0 to 1 and indicates the proportion of the variance in the dependent variable that can be explained by the independent variable in the model.
A high value of R-squared (close to 1) means that the regression line explains a large proportion of the variation in the outcome variable, while a low value of R-squared (close to 0) means that the regression line explains very little of the variation in the outcome variable.

a) To compute the coefficient of determination, we need to first calculate the correlation coefficient (r) between the predictor variable and the outcome variable. Once we have the correlation coefficient, we can square it to get the R-squared value.
For example, if the correlation coefficient between the predictor variable and the outcome variable is 0.75, then the R-squared value would be:
R-squared = 0.75^2 = 0.5625
Therefore, the coefficient of determination is 0.5625.
b) The coefficient of determination (R-squared) tells us how much of the variation in the outcome variable is explained by the least squares regression line. Specifically, R-squared ranges from 0 to 1 and indicates the proportion of the variance in the dependent variable that can be explained by the independent variable in the model.
For example, if the R-squared value is 0.5625, then we can say that the regression line explains 56.25% of the variation in the outcome variable. The remaining 43.75% of the variation is due to other factors that are not included in the model.

The cost of producing 100 items is approximately $1732.33. The cost is the amount of money required to produce or obtain goods or services.

The given information states that the marginal cost of producing an item is given by the equation: MC = 1.67 - 0.002x, where x represents the number of items produced.

To find the cost of producing 100 items, we need to integrate the marginal cost function to obtain the total cost function. Then we can evaluate the total cost when x = 100.

The total cost (TC) can be found by integrating the marginal cost (MC) function:

TC = ∫ MC dx

Integrating the given marginal cost function:

TC = ∫ (1.67 - 0.002x) dx

To find the constant of integration, we need additional information. Let's use the fact that the cost of producing one item is $1572.

When x = 1, TC = 1572. Therefore, we can set up the equation:

∫ (1.67 - 0.002x) dx = 1572

Now, let's integrate the marginal cost function and solve for the constant of integration:

TC = 1.67x - 0.001x^2/2 + C

To find the constant C, we can substitute the values from the given information:

1572 = 1.67(1) - 0.001(1)^2/2 + C

1572 = 1.67 - 0.001/2 + C

1572 = 1.67 - 0.0005 + C

C = 1572 - 1.67 + 0.0005

C ≈ 1570.3305

Now, we have the total cost function:

TC = 1.67x - 0.001x^2/2 + 1570.3305

To find the cost of producing 100 items, we substitute x = 100 into the total cost function:

TC(100) = 1.67(100) - 0.001(100)^2/2 + 1570.3305

TC(100) = 167 - 0.001(10000)/2 + 1570.3305

TC(100) = 167 - 5 + 1570.3305

To find the flux of the vector field F = (x, ln(y^2 + 1), -3z) across the part of the paraboloid z = 2 - x^2 - y^2 that lies above the plane z = 1 and is oriented upwards, we can use the Divergence Theorem.

The Divergence Theorem states that the flux of a vector field across a closed surface is equal to the triple integral of the divergence of the vector field over the volume enclosed by the surface.

First, we need to determine the bounds for the triple integral. The part of the paraboloid that lies above the plane z = 1 can be described by the following inequalities: z ≥ 1 and z ≤ 2 - x^2 - y^2. Rearranging the second inequality, we get x^2 + y^2 ≤ 2 - z.

To evaluate the triple integral, we integrate the divergence of F over the volume enclosed by the surface. The divergence of F is given by ∇ · F = ∂F/∂x + ∂F/∂y + ∂F/∂z. Computing the partial derivatives and simplifying, we find ∇ · F = 1 - 2x.

Thus, the flux of F across the specified part of the paraboloid is equal to the triple integral of (1 - 2x) over the volume bounded by x^2 + y^2 ≤ 2 - z, 1 ≤ z ≤ 2, and oriented upwards.

In summary, the Divergence Theorem allows us to calculate the flux of a vector field across a closed surface by evaluating the triple integral of the divergence of the field over the volume enclosed by the surface. In this case, we determine the bounds for the triple integral based on the given region and the orientation of the surface. Then we integrate the divergence of the vector field over the volume to obtain the flux value.

The radius of convergence is 1/2.

The summing of discrete data is indicated by the integration. To determine the functions that will characterize the area, displacement, and volume that result from a combination of small data that cannot be measured separately, integrals are calculated.

To find the radius of convergence (R) and interval of convergence for the series ∑ₙ₌₁ (2x)ⁿ/n, we can use the ratio test.

The ratio test states that for a power series ∑ₙ₌₀ aₙxⁿ, if the limit of |aₙ₊₁/aₙ| as n approaches infinity exists, then the series converges if the limit is less than 1 and diverges if the limit is greater than 1.

Let's apply the ratio test to the given series:

|aₙ₊₁/aₙ| = |(2x)ⁿ⁺¹/(n+1)| / |(2x)ⁿ/n|

Simplifying the expression, we have:

|aₙ₊₁/aₙ| = |2x(n+1)/(n+1)| / |2xn/(n)| = |2x|

Since the limit of |2x| as n approaches infinity is always |2x|, we need |2x| < 1 for convergence.

Thus, we have:

-1 < 2x < 1

Dividing the inequality by 2, we get:

-1/2 < x < 1/2

Therefore, the interval of convergence is (-1/2, 1/2).

To find the radius of convergence R, we take half the length of the interval of convergence:

R = (1/2 - (-1/2))/2 = 1/2

Hence, the radius of convergence is 1/2.

The pigeonhole principle guarantees that at least (C) 13 students were born on the same day of the week, and 7 in the same month.

Given information: 87 students are enrolled in Math 2B and Math 22 classes.

We have to determine the pigeonhole principle guarantees that at least how many students were born on the same day of the week, and in the same month.

There are 7 days in a week, so in the worst-case scenario, each of the 87 students was born on a different day of the week.

In such a situation, at least 87/7=12 students would have been born on the same day of the week.

Therefore, option (A) and option (B) are eliminated.

There are 12 months in a year, so in the worst-case scenario, each of the 87 students was born in a different month.

In such a situation, at least 87/12=7 students would have been born in the same month.

Therefore, option (C) and option (D) are left.

To find the centroid of the region bounded by the curves y = sin(5x), y = 0, x = 0, and x = 1, we need to calculate the x-coordinate and y-coordinate of the centroid.

First, let's find the x-coordinate of the centroid. The x-coordinate of the centroid is given by the formula: x-bar = (1/Area) * ∫[a, b] (x * f(x)) dx,

where f(x) is the given function and [a, b] is the interval of integration. In this case, the interval of integration is [0, 1] and the function is y = sin(5x). To calculate the area, we can integrate the function f(x) = sin(5x) over the interval [0, 1]:

Area = ∫[0, 1] sin(5x) dx.

Next, we calculate the integral of x * f(x) = x * sin(5x) over the interval [0, 1]:  ∫[0, 1] (x * sin(5x)) dx.

Once we have the values of the area and the integral, we can find the x-coordinate of the centroid by dividing the integral by the area. Next, let's find the y-coordinate of the centroid. The y-coordinate of the centroid is given by the formula: y-bar = (1/Area) * ∫[a, b] (0.5 * f(x)^2) dx. In this case, since y = sin(5x), we have y-bar = (1/Area) * ∫[a, b] (0.5 * sin(5x)^2) dx.

Again, we calculate the integral over the interval [0, 1], and then divide by the area to find the y-coordinate of the centroid. By calculating the integrals and performing the necessary calculations, we can determine the coordinates of the centroid of the region bounded by the given curves.

Log(21) is the power to which 10 must be raised to get 21.

(a) to find the principal value of log(21), we need to determine the exponent to which the base (in this case, 10) must be raised to obtain the number 21. mathematically, we can express this as:log(21) = x   ⟹   10ˣ = 21.to find the value of x, we can use logarithmic properties:x = log(21) = log(10ˣ) = x * log(10).

this implies that x * log(10) = x. dividing both sides by x yields:log(10) = 1., the principal value of log(21) is 1.(b) the principal value of (-1) can be found by taking the logarithm base 10 of (-1). however, it's important to note that the logarithm function is not defined for negative numbers. , the principal value of log(-1) is undefined.

There are 50,000 nanoseconds (ns) in 50 milliseconds (µs).

To convert milliseconds (ms) to nanoseconds (ns), we need to know the conversion factor between the two units.

1 millisecond (ms) is equal to 1,000 microseconds (µs). And 1 microsecond (µs) is equal to 1,000 nanoseconds (ns). Therefore, we can use this information to convert milliseconds to nanoseconds.

Since we have 50 milliseconds (µs), we can multiply this value by the conversion factor to obtain the equivalent value in nanoseconds.

50 milliseconds (µs) * 1,000 microseconds (µs) * 1,000 nanoseconds (ns) = 50,000 nanoseconds (ns).

The iterated integral of (%* cos(x + y)) with respect to dy, evaluated from 0 to 27, can be computed as follows: [tex]∫[0,27][/tex] (%* cos(x + y)) dy = % * sin(x + 27) - % * sin(x).

To calculate the iterated integral, we start by integrating the function (%* cos(x + y)) with respect to dy, treating x as a constant. Integrating cos(x + y) with respect to y gives us sin(x + y), so the integral becomes ∫(%* sin(x + y)) dy. We then evaluate this integral from the lower limit 0 to the upper limit 27.

When integrating sin(x + y) with respect to y, we get -cos(x + y), but since we are evaluating the integral over the limits 0 to 27, the antiderivative of sin(x + y) becomes -cos(x + 27) - (-cos(x + 0)) = -cos(x + 27) + cos(x). Multiplying this result by the constant % gives us % * (-cos(x + 27) + cos(x)).

Simplifying further, we can distribute the % to both terms: % * (-cos(x + 27) + cos(x)) = % * -cos(x + 27) + % * cos(x). Rearranging the terms, we have % * cos(x + 27) - % * cos(x).

Therefore, the iterated integral of (%* cos(x + y)) with respect to dy, evaluated from 0 to 27, is % * cos(x + 27) - % * cos(x).

The first three non-zero terms of the series for [tex]e^{2x} cos(3x)[/tex]are:

[tex]1 - 3x^2/2 + x^4/8[/tex]

To find the series for V1 + x, we can start by expanding V1 in a Taylor series around x = 0 and then add x to it.

Let's assume the Taylor series expansion for V1 around x = 0 is given by:

[tex]V1 = a_0 + a_1x + a_2x^2 + a_3x^3 + ...[/tex]

Adding x to the series:

[tex]V1 + x = (a_0 + a_1x + a_2x^2 + a_3x^3 + ...) + x\\= a_0 + (a_1 + 1)x + a_2x^2 + a_3x^3 + ...[/tex]

Now, let's approximate V1.01 using the series expansion. We substitute x = 0.01 into the series:

[tex]V1.01 = a_0 + (a_1 + 1)(0.01) + a_2(0.01)^2 + a_3(0.01)^3 + ...[/tex]

To approximate V1.01 to three decimal places, we can truncate the series after the term involving [tex]x^{3}[/tex]. Therefore, the approximation becomes:

V1.01 ≈ [tex]a_0 + (a_1 + 1)(0.01) + a_2(0.01)^2 + a_3(0.01)^3+..........[/tex]

Now, let's move on to the second question:

The series for [tex]e^{2x} cos(3x)[/tex] can be found by expanding both e^(2x) and cos(3x) in separate Taylor series around x = 0, and then multiplying the resulting series.

The Taylor series expansion for [tex]e^{2x}[/tex] around x = 0 is:

[tex]e^{2x} = 1 + 2x + (2x)^2/2! + (2x)^3/3! + ...[/tex]

The Taylor series expansion for cos(3x) around x = 0 is:

[tex]cos(3x) = 1 - (3x)^2/2! + (3x)^4/4! - (3x)^6/6! + ...[/tex]

To find the series for [tex]e^{2x} cos(3x)[/tex], we multiply the corresponding terms from both series:

[tex](e^{2x} cos(3x)) = (1 + 2x + (2x)^2/2! + (2x)^3/3! + ...) * (1 - (3x)^2/2! + (3x)^4/4! - (3x)^6/6! + ...)[/tex]

Expanding this product will give us the series for e^(2x) cos(3x).

To find the first three non-zero terms of the series, we need to multiply the first three non-zero terms of the two series and simplify the result.

The first three non-zero terms are:

Term 1: 1 * 1 = 1

Term 2: 1 *[tex](-3x)^2/2! = -3x^2/2[/tex]

Term 3: 1 *[tex](3x)^4/4! = 3x^4/24 = x^4/8[/tex]

The value of derivative f'(2) is 4 cos(2).

The given function is f(x) = 4 sin(x). We need to find f'(2), which represents the derivative of f(x) evaluated at x = 2.

To find f'(x), we differentiate f(x) using the chain rule. The derivative of sin(x) is cos(x), and the derivative of 4 sin(x) is 4 cos(x).

Applying the chain rule, we have:

f'(x) = 4 cos(x)

Now, to find f'(2), we substitute x = 2 into the derivative:

f'(2) = 4 cos(2)

We are given the function f(x) = 4 sin(x), which represents a sinusoidal function. To find the derivative, we use the chain rule. The derivative of sin(x) is cos(x), and since there is a coefficient of 4, it remains as 4 cos(x).

By applying the chain rule, we find the derivative of f(x) to be f'(x) = 4 cos(x). To evaluate f'(2), we substitute x = 2 into the derivative, resulting in f'(2) = 4 cos(2). Thus, f'(2) represents the slope or rate of change of the function at x = 2, which is 4 times the cosine of 2.
