Find the Taylor polynomials Pz..... Ps centered at a = 0 for f(x) = 2 e -*.

The domain of the function f is {a, 6, c, d}, and the range of the function f is {2, 3, 4, 5}. The function f(b) is not defined because b is not in the domain of the function. However, f(d) is 5.

In this case, the domain of the function f is determined by the elements in the set A, which are {a, b, c, d}. In this case, the range of the function f is determined by the second elements in each ordered pair of the function f, which are {2, 3, 4, 5}.

Since the element b is not included in the domain of the function f, f(b) is not defined. It means there is no corresponding output value for the input b in the function f.

However, the element d is in the domain of the function f, and its corresponding output value is 5. Therefore, f(d) is equal to 5.

y - 3 = 1(x - 1)y = x + 2 38.

y = (1/4)x + 2. 39.

y = -x + 2. 40.

y = (1/2)x + 1/2.

35) Given: y = x² + x To find: Find dy/dx Expand y = x² + x = x(x+1) Now, differentiate using the product rule: dy/dx

= x(d/dx(x+1)) + (x+1)(d/dx(x))dy/dx

= x(1) + (x+1)(1)dy/dx = 2x+1.

Hence, the solution is dy/dx = 2x+1.

37) Given: y = 2x - x + 2 = x + 2To find :Find an equation of the tangent line to the curve at the given point. Point of tangency = (1, 3) The slope of the tangent line is given by the derivative at the given point, i.e.,dy/dx = d/dx(x+2) = 1 Therefore, the equation of the tangent line at the point (1,3) is given by: y - 3 = 1(x - 1)y = x + 2

The possible values of the real number m, for which the quadratic equation 2x² + mx + 8 has two distinct real roots, are m ∈ (-16, 16) excluding m = 0.

What is a real number?

A real number is a number that can be expressed on the number line. It includes rational numbers (fractions) and irrational numbers (such as square roots of non-perfect squares or transcendental numbers like π).

For a quadratic equation of the form ax² + bx + c = 0 to have two distinct real roots, the discriminant (b² - 4ac) must be greater than zero. In this case, we have a = 2, b = m, and c = 8.

The discriminant can be expressed as m² - 4(2)(8) = m² - 64. For two distinct real roots, we require m² - 64 > 0.

Solving this inequality, we get m ∈ (-∞, -8) ∪ (8, ∞).

However, since the original question states that m is a real number, we exclude any values of m that would result in the quadratic equation having a double root.

By analyzing the discriminant, we find that m = 0 would result in a double root. Therefore, the final answer is m ∈ (-16, 16) excluding m = 0, expressed in interval notation.

Answer:

The missing angle γ=17.97°.

Let's have detailed explanation:

Since the information given includes the angles of the triangle (76°, 74°, and γ), and the lengths of two sides (a=13.2 and b), we can use the Law of Cosines formula to solve for the missing side (b): b^2 = a^2 + c^2 − 2ac cos(γ).

Therefore, b = sqrt(13.2^2 + 76^2 - 2(13.2)(76) * cos(γ)).

To solve for the value of γ, we can use the Law of Cosines formula once again: cos(γ) = (a^2+b^2-c^2)/2ab.

Substituting in the values for a, b, and c then gives us:

cos(γ) = (13.2^2+sqrt(13.2^2 + 76^2 - 2(13.2)(76) * cos(γ))-76^2)/(2*13.2*sqrt(13.2^2 + 76^2 - 2(13.2)(76) * cos(γ))).

The possible solutions from the triangle are c = 25.6 units, b = 25.4 units and A = 30 degrees

From the question, we have the following parameters that can be used in our computation:

C = 76 degrees

a = 13.2 units

B = 74 degrees

The sum of angles in a triangle is 180 degrees

So, we have

So, we have

b/sin(74) = 13.2/sin(30)

This gives

b = sin(74 deg) * 13.2/sin(30 deg)

Evaluate

b = 25.4

To determine the velocity and acceleration of the particle, we need to differentiate the position function with respect to time.

a. Velocity:

To find the velocity, we differentiate the position function with respect to time (t):

v(t) = d/dt [a(t)] = d/dt [t/e^t]

To differentiate the function, we can use the quotient rule:

v(t) = [e^t - t(e^t)] / e^(2t)

Simplifying further:

v(t) = e^t(1 - t) / e^(2t)

    = (1 - t) / e^t

Therefore, the velocity of the particle is given by v(t) = (1 - t) / e^t.

b. Acceleration:

To find the acceleration, we differentiate the velocity function with respect to time (t):

a(t) = d/dt [v(t)] = d/dt [(1 - t) / e^t]

Differentiating using the quotient rule:

a(t) = [(e^t - 1)(-1) - (1 - t)(e^t)] / e^(2t)

Simplifying further:

a(t) = (-e^t + 1 + te^t) / e^(2t)

Therefore, the acceleration of the particle is given by a(t) = (-e^t + 1 + te^t) / e^(2t).

These are the expressions for velocity and acceleration in terms of time for the given particle's motion.

The value of constant "a" is approximately 24.961.

To find the constant "a" given that the length of the polar curve is 157, we need to evaluate the integral representing the arc length of the curve.

The arc length of a polar curve is given by the formula:

L = ∫[α, β] √(r² + (dr/dθ)²) dθ

In this case, the polar curve is represented by r = a sin(θ), where 0 ≤ θ ≤ 2π. Let's calculate the arc length:

L = ∫[0, 2π] √(a² sin²(θ) + (d/dθ(a sin(θ)))²) dθ

L = ∫[0, 2π] √(a² sin²(θ) + a² cos²(θ)) dθ

L = ∫[0, 2π] √(a² (sin²(θ) + cos²(θ))) dθ

L = ∫[0, 2π] a dθ

L = aθ | [0, 2π]

L = a(2π - 0)

L = 2πa

Given that L = 157, we can solve for "a":

2πa = 157

a = 157 / (2π)

After using Newton's law of cooling, we found that the murder happened 41 minutes before the team arrived.

Minutes before the team's arrival. We can use Newton's law of cooling to solve the given problem. According to this law, the rate at which a body cools is proportional to the difference between the temperature of the body and the temperature of the surrounding air.

Mathematically, this is given as:

[tex]$$\frac{d T}{d t}=-k(T-T_{0})$$[/tex] where T is the temperature of the body, T0 is the temperature of the surrounding air, k is a constant, and t is time. Let us solve the differential equation.

[tex]$$dT/dt=-k(T-T_{0})$$$$\Rightarrow \frac{dT}{T-T_{0}}=-kdt$$[/tex]

Integrating both sides, we get:

[tex]$$\ln|T-T_{0}|=-kt+c$$$$\Rightarrow T-T_{0}=e^{kt+c}$$$$\Rightarrow T-T_{0}=De^{kt}$$where D = e^c[/tex] is a constant.

We can determine the value of D using the given data.

At t = 0, T = 37°C and T0 = 18°C.

Therefore,[tex]$$D=T-T_{0}=37-18=19$$[/tex]

Also, at t = 10 minutes, T = 21°C.

Therefore[tex],$$T-T_{0}=19e^{10k}=21-18=3$$$$\Rightarrow e^{10k}=\frac{3}{19}$$$$\Rightarrow k=\frac{1}{10}\ln\left(\frac{3}{19}\right)$$[/tex]

Putting the value of k in the equation [tex]$T - T_0 = De^{kt}$, we get:$$T-T_{0}=19e^{\frac{1}{10}\ln\left(\frac{3}{19}\right)t}=19\left(\frac{3}{19}\right)^{\frac{1}{10}t}$$[/tex]

Let us solve for t when T = 25°C. [tex]$$T-T_{0}=19\left(\frac{3}{19}\right)^{\frac{1}{10}t}=25-18=7$$$$\Rightarrow \left(\frac{3}{19}\right)^{\frac{1}{10}t}=\frac{7}{19}$$$$\Rightarrow t=\frac{10}{\ln(3/19)}\ln(7/19)\approx\boxed{41 \text{ minutes}}$$[/tex]

The allocation of labor and capital that will minimize total production costs for the facility, given the Cobb-Douglas Production function P(L, K) = 18L^0.5 K^0.5 and the cost function C(L, K) = 400L + 200K, is approximately L = 37.5 units of labor and K = 37.5 units of capital.

The minimal cost to produce 6,000 units, using the rounded values for L and K from above, is $29,375.

To find the allocation of labor and capital that minimizes production costs, we need to solve the problem by taking partial derivatives of the cost function with respect to labor (L) and capital (K) and setting them equal to zero. This will help us find the critical points where the cost is minimized.

The partial derivatives of the cost function C(L, K) with respect to L and K are:

[tex]dC/dL = 400\\dC/dK = 200[/tex]

Setting these partial derivatives equal to zero, we find that L = 0 and K = 0, which represents the origin point (0,0).

However, since investing zero units of labor and capital would not allow us to meet the production goal of 6,000 units, we need to find another critical point.

Next, we can use the Cobb-Douglas Production function to find the relationship between labor and capital that satisfies the production goal.

Setting P(L, K) equal to 6,000 and substituting the given values, we get:

18L^0.5 K^0.5 = 6,000

Simplifying this equation, we find that L^0.5 K^0.5 = 333.33. By squaring both sides of the equation, we have LK = 111,111.11.

Now, we can solve the system of equations LK = 111,111.11 and dC/dL = 400, dC/dK = 200 to find the values of L and K that minimize the cost. The solution is approximately L = 37.5 and K = 37.5.

Using these rounded values, we can calculate the minimal cost to produce 6,000 units by substituting L = 37.5 and K = 37.5 into the cost function [tex]C(L, K) = 400L + 200K.[/tex] The minimal cost is $29,375.

The equation of the tangent to the curve y = 5√x at x = 4 is y = 10x - 20. The first derivative test reveals that the function y = x² - 1 has a minimum at x = 0. The concavity of the function -3t ye-e is determined to be upward (concave up), and it has no inflection points.

To determine the equation of the tangent to the curve y = 5√x at x = 4, we first need to find the derivative of the function. The derivative of y = 5√x can be found using the power rule for differentiation, which states that d/dx(x^n) = nx^(n-1).

Applying this rule, the derivative of y = 5√x is dy/dx = 5(1/2)x^(-1/2) = 5/(2√x).

Next, we substitute x = 4 into the derivative to find the slope of the tangent line at that point: dy/dx = 5/(2√4) = 5/4.

Now that we have the slope, we can use the point-slope form of the equation of a line, y - y1 = m(x - x1), where (x1, y1) is the point of tangency and m is the slope. Plugging in x1 = 4, y1 = 5√4 = 10, and m = 5/4, we get y - 10 = (5/4)(x - 4), which simplifies to y = 10x - 20. Therefore, the equation of the tangent to the curve y = 5√x at x = 4 is y = 10x - 20.

For the function y = x² - 1, we can determine the maximum or minimum by using the first derivative test. Taking the derivative of y = x² - 1 with respect to x gives dy/dx = 2x.

To find critical points, we set the derivative equal to zero and solve for x: 2x = 0, which gives x = 0.

To determine whether x = 0 corresponds to a maximum or minimum, we evaluate the second derivative at x = 0.

Taking the derivative of dy/dx = 2x with respect to x, we get d²y/dx² = 2. Since the second derivative is positive, we conclude that the function is concave up and x = 0 corresponds to a minimum.

For the function -3t ye-e, we can determine concavity and inflection points by finding the second derivative. Taking the derivative of -3t ye-e with respect to t, we get d/dt(-3t ye-e) = -3 ye-e + 3t ye-e.

To find inflection points, we set the second derivative equal to zero and solve for t: -3 ye-e + 3t ye-e = 0. However, this equation cannot be solved algebraically to find specific values of t. Therefore, we conclude that the function -3t ye-e does not have any inflection points.

Additionally, since the second derivative d²y/dx² = 2 is positive, the function is concave up.

The equation of the tangent line to the graph of f(x) = -2cos(x) at x = π/4 is:

y =[tex]\sqrt{2}x - \frac{\pi\sqrt{2}}{2} - \sqrt{2}[/tex]

To find the equation of the tangent line to the graph of f(x) = -2cos(x) at x = π/4, we need to determine the slope of the tangent line and the point of tangency.

First, let's find the derivative of f(x) with respect to x to obtain the slope of the tangent line:

f'(x) = d/dx (-2cos(x))

Using the chain rule, we have:

f'(x) = 2sin(x)

Now, let's find the slope of the tangent line at x = π/4:

m = [tex]f'(\frac{\pi}{4}) = 2sin(\frac{\pi}{4}) = 2(\frac{\sqrt{2}}{2}) = \sqrt{2}[/tex]

Next, we need to find the y-coordinate of the point of tangency. We substitute x = π/4 into the original function:

[tex]f(\frac{\pi}{4}) = -2cos(\frac{\pi}{4}) = -2(\frac{\sqrt{2}}{2}) = -\sqrt{2}[/tex]

Therefore, the point of tangency is [tex](\frac{\pi}{4}, -\sqrt{2})[/tex].

Finally, we can write the equation of the tangent line using the point-slope form:

[tex]y - y_0 = m(x - x_0)[/tex]

Plugging in the values, we get:

[tex]y - (-\sqrt{2}) = \sqrt{2}(x - \frac{\pi}{4})[/tex]

Simplifying the equation gives the final answer:

[tex]y + \sqrt{2} = \sqrt{2}x - \frac{\pi\sqrt{2}}{2}[/tex]

The pattern observed in polar equations of the form r = sin(kθ) involves k-fold symmetry, where the value of k determines the number of waves or lobes in the graph. This pattern arises due to the nature of the sine function and the effect of the factor k on its argument.

Step-by-step explanation:

When exploring polar equations of the form r = sin(kθ), where k is a natural number, we can observe an interesting pattern. Let's investigate this pattern further by experimenting with different values of k using a graphing program like Desmos.

As we vary the value of k, we notice that the resulting polar graphs exhibit k-fold symmetry. In other words, the graph repeats itself k times as we traverse a full revolution (2π) around the origin.

For example, when k = 1, the polar graph of r = sin(θ) represents a single wave that completes one cycle as θ varies from 0 to 2π.

When k = 2, the polar graph of r = sin(2θ) displays two waves that repeat themselves twice as θ varies from 0 to 2π. The graph is symmetric with respect to the polar axis (θ = 0) and the vertical line (θ = π/2).

Similarly, for larger values of k, such as k = 3, 4, 5, and so on, the resulting polar graphs exhibit 3-fold, 4-fold, 5-fold symmetry, respectively. The number of waves or lobes in the graph increases with the value of k.

To explain why this pattern holds, we can analyze the behavior of the sine function. The sine function has a period of 2π, meaning it repeats itself every 2π units. When we introduce the factor of k in the argument, such as sin(kθ), it effectively compresses or stretches the graph horizontally by a factor of k.

Thus, when k is an even number, the graph becomes symmetric with respect to both the polar axis and vertical lines, resulting in k-fold symmetry. The lobes or waves of the graph increase in number as k increases. On the other hand, when k is an odd number, the graph retains symmetry with respect to the polar axis but lacks symmetry with respect to vertical lines.

In summary, the pattern observed in polar equations of the form r = sin(kθ) involves k-fold symmetry, where the value of k determines the number of waves or lobes in the graph. This pattern arises due to the nature of the sine function and the effect of the factor k on its argument.

The angle coterminal to 1760 degrees, between 0 and 360 degrees, is 40 degrees.

To find an angle coterminal to 1760 degrees within the range of 0 to 360 degrees, we need to subtract or add multiples of 360 degrees until we obtain an angle within the desired range.

Starting with 1760 degrees, we can subtract 360 degrees to get 1400 degrees. Since this is still outside the range, we continue subtracting 360 degrees until we reach an angle within the range. Subtracting another 360 degrees, we get 1040 degrees. Continuing this process, we subtract 360 degrees three more times and reach 40 degrees, which falls within the range of 0 to 360 degrees. Therefore, 40 degrees is coterminal to 1760 degrees in the specified range.

In summary, the angle 40 degrees is coterminal to 1760 degrees within the range of 0 to 360 degrees. This is achieved by subtracting multiples of 360 degrees from 1760 degrees until we obtain an angle within the desired range, leading us to the final result of 40 degrees.

To find the Maclaurin series for the function f(x) = cos(3x) - sin(x^2), we need to expand the function into a power series centered at x = 0. By using the known Maclaurin series expansions for cosine and sine functions, we can substitute these expansions into f(x) and simplify. The first six terms of the Maclaurin series for f(x) are 1 - 9x^2/2 + 27x^4/24 - 1x^6/48 + O(x^7). To find the Maclaurin series for f(x) = cos(3x) - sin(x^2), we need to expand the function into a power series centered at x = 0. The Maclaurin series expansions for cosine and sine functions are:

The question asks for the surface area generated by revolving the function f(x) = x from x = 0 to x = 4 about the x-axis.

To find the surface area generated by revolving a function about the x-axis, we can use the formula for surface area of revolution. The formula is given by: SA = 2π ∫[a,b] f(x) √(1 + (f'(x))^2) dx. In this case, the function f(x) = x is a linear function, and its derivative is f'(x) = 1. Substituting these values into the formula, we have: SA = 2π ∫[0,4] x √(1 + 1^2) dx = 2π ∫[0,4] x √2 dx = 2π (√2/3) [x^(3/2)] [0,4] = 2π (√2/3) [(4)^(3/2) - (0)^(3/2)] = 2π (√2/3) (8). Therefore, the surface area generated by revolving f(x) = x from x = 0 to x = 4 about the x-axis is 16π√2/3.

The integral is ∫(dx / (1 + x^3)) = (1/3) ln|1 + x^3| + C The integral is convergent since it evaluates to a finite value.

To determine whether each integral is convergent or divergent, we will evaluate them individually:

∫(-5p dp) from e to 2

To evaluate this integral, we integrate -5p with respect to p:

∫(-5p dp) = -5∫p dp = -5 * (p^2/2) = -5p^2/2

Now, we evaluate the integral from e to 2:

∫(-5p dp) from e to 2 = [-5(2)^2/2] - [-5(e)^2/2]

= -20/2 - (-5e^2/2)

= -10 - (-2.5e^2)

= -10 + 2.5e^2

Since the result of the integral is a finite value (-10 + 2.5e^2), the integral is convergent.

∫(dx / (1 + x^3))

To evaluate this integral, we need to find the antiderivative of 1 / (1 + x^3) with respect to x:

Let's substitute u = 1 + x^3, then du = 3x^2 dx

Dividing both sides by 3: (1/3) du = x^2 dx

Rearranging the equation: dx = (1/3x^2) du

Substituting the values back into the integral:

∫(dx / (1 + x^3)) = ∫((1/3x^2) du / u)

= (1/3) ∫(du / u)

= (1/3) ln|u| + C

= (1/3) ln|1 + x^3| + C

The function f(x) = -x^4 - 6x^3 + 2x + 4 is concave up on the interval (-3, 0) and concave down on the interval (-∞, -3) ∪ (0, +∞). The inflection point(s) occur at x = -3 and x = 0.

To determine the concavity of the function, we need to find the second derivative of f(x) and analyze its sign. First, find the second derivative of f(x):

f''(x) = -12x^2 - 36x + 2

To find the intervals where f(x) is concave up, we need to identify where f''(x) is positive:

-12x^2 - 36x + 2 > 0

By solving this inequality, we find that f''(x) is positive on the interval (-3, 0). Similarly, to find the intervals where f(x) is concave down, we need to identify where f''(x) is negative:

-12x^2 - 36x + 2 < 0

By solving this inequality, we find that f''(x) is negative on the interval (-∞, -3) ∪ (0, +∞). Next, to find the inflection points, we need to identify where the concavity changes. This occurs when f''(x) changes sign, which happens at the points where f''(x) equals zero:

-12x^2 - 36x + 2 = 0

By solving this equation, we find that the inflection points occur at x = -3 and x = 0. In summary, the function f(x) is concave up on the interval (-3, 0) and concave down on the interval (-∞, -3) ∪ (0, +∞). The inflection points of f(x) are located at x = -3 and x = 0.

To find the area enclosed by the loop of the curve, we need to determine the range of t-values where the loop occurs. By analyzing the curve's behavior, we can observe that the loop occurs when the curve intersects itself.

Solving the equation for x = t³ - 3t and y = t² + t + 1 simultaneously, we find that the curve intersects itself at two points: (t₁, y₁) and (t₂, y₂).

Once the points of intersection are determined, we can calculate the area enclosed by the loop using the definite integral:

Area = ∫[t₁, t₂] (y * dx)

By evaluating this integral using the given equations for x and y, the resulting value will represent the area enclosed by the loop of the curve.

the series ∑(4 + sin(n))/(2n + 3) is divergent but conditionally convergent. To determine the convergence of the series ∑(4 + sin(n))/(2n + 3), we need to analyze its absolute convergence, conditional convergence, or divergence.

Absolute Convergence:

We start by considering the absolute value of each term in the series. Taking the absolute value of (4 + sin(n))/(2n + 3), we have |(4 + sin(n))/(2n + 3)|. Now, let's apply the limit comparison test to determine if the series is absolutely convergent. We compare it to a known convergent series with positive terms, such as the harmonic series ∑(1/n). Taking the limit as n approaches infinity of the ratio of the two series: lim(n->∞) |(4 + sin(n))/(2n + 3)| / (1/n) = lim(n->∞) n(4 + sin(n))/(2n + 3). Since the limit evaluates to a nonzero finite value, the series ∑(4 + sin(n))/(2n + 3) diverges.

Conditional Convergence:

To determine if the series ∑(4 + sin(n))/(2n + 3) is conditionally convergent, we need to check if the series converges when we remove the absolute value.

By removing the absolute value, we have ∑(4 + sin(n))/(2n + 3). To analyze the convergence of this series, we can use the alternating series test since the terms alternate in sign (positive and negative) due to the sin(n) component. We need to check two conditions: The terms approach zero: lim(n->∞) (4 + sin(n))/(2n + 3) = 0 (which it does). The terms are monotonically decreasing: |(4 + sin(n))/(2n + 3)| ≥ |(4 + sin(n + 1))/(2(n + 1) + 3)|.

Since both conditions are satisfied, the series ∑(4 + sin(n))/(2n + 3) is conditionally convergent.

The probability of picking a heart given that the card is a four is 1/13 (approximately 0.077). The probability of picking a four given that the card is a heart is 1/4 (0.25).

To calculate the probability of picking a heart given that the card is a four, we need to consider the fact that there are four hearts in a deck of 52 cards. Since there is only one four of hearts in the deck, the probability is given by 1/52 (the probability of picking the four of hearts) divided by 1/13 (the probability of picking any four from the deck). This simplifies to 1/13.

On the other hand, to calculate the probability of picking a four given that the card is a heart, we need to consider the fact that there are four fours in a deck of 52 cards. Since all four fours are hearts, the probability is given by 4/52 (the probability of picking any four from the deck) divided by 1/4 (the probability of picking any heart from the deck).

To find the work done in pumping the entire contents of the cylindrical gasoline tank into the tractor, we need to calculate the integral of the weight of the gasoline over the volume of the tank. The weight can be determined from the density of gasoline, and the volume of the tank can be calculated using the dimensions given.

The weight of the gasoline can be found using the density of 42 pounds per cubic foot. The volume of the tank can be calculated as the product of the cross-sectional area and the length of the tank. The cross-sectional area of a cylinder is πr^2, where r is the radius of the tank (which is half of the diameter). Given that the tank has a diameter of 3 feet, the radius is 1.5 feet. The length of the tank is 4 feet. The volume of the tank is therefore V = π(1.5^2)(4) = 18π cubic feet.

To calculate the work done in pumping the entire contents of the tank, we need to integrate the weight of the gasoline over the volume of the tank. The weight per unit volume is the density, which is 42 pounds per cubic foot. The integral for the work done is then:

Work = ∫(density)(dV)

where dV represents an infinitesimally small volume element. In this case, we integrate over the entire volume of the tank, which is 18π cubic feet. The exact calculation of the integral requires further details on the pumping process, such as the force applied and the path followed during the pumping. Without this information, we can set up the integral but cannot evaluate it.

In summary, the work done in pumping the entire contents of the fuel tank into the tractor can be determined by calculating the integral of the weight of the gasoline over the volume of the tank. The volume can be calculated from the given dimensions, and the weight can be determined from the density of the gasoline. The exact evaluation of the integral depends on further information about the pumping process.

The evaluation of ∫ F · dr, where F = (4, -3y, -4z) and C is given by r(t) = (t, sin(t), cos(t)), 0 ≤ t ≤ π, is [84, 2 - cos(t), -4sin(t)] evaluated at the endpoints of the curve C.

To evaluate the line integral, we need to parameterize the curve C and compute the dot product between the vector field F and the tangent vector dr/dt. Let's consider the parameterization r(t) = (t, sin(t), cos(t)), where t ranges from 0 to π.

Taking the derivative of r(t), we have dr/dt = (1, cos(t), -sin(t)). Now, we can compute the dot product F · (dr/dt) as follows:

F · (dr/dt) = (4, -3y, -4z) · (1, cos(t), -sin(t)) = 4(1) + (-3sin(t))cos(t) + (-4cos(t))(-sin(t))

Simplifying further, we get F · (dr/dt) = 4 - 3sin(t)cos(t) + 4sin(t)cos(t) = 4.

Since the dot product is constant, the value of the line integral ∫ F · dr over the curve C is simply the dot product (4) multiplied by the length of the curve C, which is π - 0 = π.

Therefore, the evaluation of ∫ F · dr over the curve C is π times the constant vector [84, 2 - cos(t), -4sin(t)], which gives the final answer as [84π, 2π - 1, -4πsin(t)] evaluated at the endpoints of the curve C.
