The difference quotient for the function f(x) = x^3 - 5x is calculated for different values of h: 0.1, 0.01, -0.01, and -0.1. The slope of the tangent line to the graph of f(x) at x = 3 is also determined. The equation of the tangent line to the curve at the point (3, 12) is provided.
The difference quotient measures the average rate of change of a function over a small interval. For f(x) = x^3 - 5x, we can calculate the difference quotient f(3+h) - f(3)/h for different values of h.
For h = 0.1:
f(3+0.1) - f(3)/0.1 = (27.1 - 12)/0.1 = 151
For h = 0.01:
f(3+0.01) - f(3)/0.01 = (27.0001 - 12)/0.01 = 1501
For h = -0.01:
f(3-0.01) - f(3)/-0.01 = (26.9999 - 12)/-0.01 = -1499
For h = -0.1:
f(3-0.1) - f(3)/-0.1 = (26.9 - 12)/-0.1 = -149
To find the slope of the tangent line at x = 3, we take the limit as h approaches 0:
lim h→0 f(3+h) - f(3)/h = lim h→0 (27 - 12)/h = 15
Therefore, the slope of the tangent line to the graph of f(x) at x = 3 is 15.
To find the equation of the tangent line, we use the point-slope form: y - y₁ = m(x - x₁), where (x₁, y₁) is the point on the curve (3, 12) and m is the slope we just found:
y - 12 = 15(x - 3)
y - 12 = 15x - 45
y = 15x - 33
Hence, the equation of the tangent line to the curve at the point (3, 12) is y = 15x - 33.

use part 1 of the fundamental theorem of calculus to find the derivative of the function. G (x) =∫4x cos (√5t)dt
G′(x)=
The derivative of G(x) with respect to x, G'(x), is equal to the integrand function g(x): G'(x) = 4x cos(√5x).
To find the derivative of the function G(x) = ∫(4x) cos(√5t) dt, we can apply Part 1 of the Fundamental Theorem of Calculus.
Fundamental Theorem of Calculus states that, if f(t) is a continuous function on the interval [a, x], where a is a constant, and F(x) is the antiderivative of f(x) on [a, x], then the derivative of the integral ∫[a,x] f(t) dt with respect to x is equal to f(x).
In this case, let's consider F(x) as the antiderivative of the integrand function g(t) = 4x cos(√5t) with respect to t. To find F(x), we need to integrate g(t) with respect to t:
F(x) = ∫ g(t) dt
= ∫ (4x) cos(√5t) dt
To find the derivative G'(x), we differentiate F(x) with respect to x:
G'(x) = d/dx [F(x)]
Now, we need to apply the chain rule since the upper limit of the integral is x and we are differentiating with respect to x. The chain rule states that if F(x) = ∫[a, g(x)] f(t) dt, then dF(x)/dx = f(g(x)) * g'(x).
Let's differentiate F(x) using the chain rule:
G'(x) = d/dx [F(x)]
= d/dx ∫[a, x] g(t) dt
= g(x) * d/dx (x)
= g(x) * 1
= g(x)
Therefore, the derivative of G(x) with respect to x, G'(x), is equal to the integrand function g(x):
G'(x) = 4x cos(√5x)
So, G'(x) = 4x cos(√5x).

If s(n) = 3n2 – 5n+2, then s(n) = 2s(n-1) – s(n − 2)+cfor all integers n > 2. What is the value of c? Answer:
To find the value of c in the equation s(n) = 2s(n-1) - s(n-2) + c, where s(n) = 3n^2 - 5n + 2, we can substitute the given expression for s(n) into the equation and simplify.
By comparing the coefficients of like terms on both sides of the equation, we can determine the value of c. Substituting s(n) = 3n^2 - 5n + 2 into the equation s(n) = 2s(n-1) - s(n-2) + c, we get:
3n^2 - 5n + 2 = 2(3(n-1)^2 - 5(n-1) + 2) - (3(n-2)^2 - 5(n-2) + 2) + c.
Expanding and simplifying, we have:
3n^2 - 5n + 2 = 6n^2 - 18n + 14 - 3n^2 + 11n - 10 + c.
Combining like terms, we get:
3n^2 - 5n + 2 = 3n^2 - 7n + 4 + c.
By comparing the coefficients of like terms on both sides of the equation, we find that c must be equal to 2.
Therefore, the value of c in the equation s(n) = 2s(n-1) - s(n-2) + c is c = 2.

To determine the horizontal asymptotes of the curve y =[tex]15x/(x^4 + 1)^(1/4),[/tex] we examine the behavior of the function as x approaches positive and negative infinity. As x becomes very large (approaching positive infinity), the denominator term[tex](x^4 + 1)^(1/4)[/tex] dominates the expression, and the value of y approaches 0. Similarly, as x becomes very large negative (approaching negative infinity), the denominator still dominates, and y also approaches 0. Therefore, y1 = 0 and y2 = 0 are the horizontal asymptotes, where y1 is greater than y2.
The vertical asymptote of the curve y = [tex]-4x^3/(x + 6)[/tex] can be found by setting the denominator equal to 0 and solving for x. In this case, when x + 6 = 0, x = -6. Thus, x = -6 is the vertical asymptote of the curve.

Consider the initial-value problem
y-4y = 5 sin 3t, y(0) = 3, y'(0) = 2.
(a) Use the Laplace transform to find Y(s).
(b) Apply the inverse Laplace transform to Y(s) found in (a) to solve the given initial-value problem.
The solution to the initial-value problem is y(t) = -(5/3) - (5/3) * cos(3t)
To solve the initial-value problem using Laplace transforms, we'll follow these steps:
(a) Use the Laplace transform to find Y(s):
The given differential equation is:
y - 4y' = 5 sin(3t)
Taking the Laplace transform of both sides using the linearity property of the Laplace transform, we get:
L(y) - 4L(y') = 5L(sin(3t))
Using the Laplace transform property for derivatives, L(y') = sY(s) - y(0), where y(0) is the initial condition.
Substituting these into the equation, we have:
sY(s) - y(0) - 4(sY(s) - y(0)) = 5 * (3 / (s^2 + 9))
Simplifying:
(s - 4s)Y(s) = 5 * (3 / (s^2 + 9)) + 4y(0) - y(0)
-3sY(s) = 15 / (s^2 + 9) + 3
Dividing both sides by -3s:
Y(s) = -(15 / (s(s^2 + 9))) - 1 / s
(b) Apply the inverse Laplace transform to Y(s) found in (a) to solve the initial-value problem:
To solve for y(t), we need to find the inverse Laplace transform of Y(s). Let's decompose Y(s) into partial fractions:
Y(s) = -(15 / (s(s^2 + 9))) - 1 / s
We can rewrite the first term as:
Y(s) = -(A / s) - (B / (s^2 + 9))
Multiplying both sides by s(s^2 + 9), we get:
-15 = A(s^2 + 9) + Bs
Let's solve for A and B:
-15 = 9A, which gives A = -15/9 = -5/3
0 = B + sA, substituting A = -5/3, we have:
0 = B + (-5/3)s, which gives B = (5/3)s
Therefore, the partial fraction decomposition is:
Y(s) = -(5/3) / s - (5/3)s / (s^2 + 9)
To find the inverse Laplace transform of Y(s), we can use the inverse Laplace transform table:
L^-1 {1 / s} = 1
L^-1 {s / (s^2 + a^2)} = cos(at)
Applying the inverse Laplace transform:
L^-1 {Y(s)} = L^-1 {-(5/3) / s} - L^-1 {(5/3)s / (s^2 + 9)}
= -(5/3) * 1 - (5/3) * cos(3t)
Therefore, the solution to the initial-value problem is:
y(t) = -(5/3) - (5/3) * cos(3t)

Explanation:The function f(x, y) = 3x4 + 3y4 - 2xy is a polynomial of degree 4 in x and y. To find the minimum value of f, we can take partial derivatives with respect to x and y and set them equal to 0. Solving these equations will give us the critical points which could be potential minima. By analyzing the second-order partial derivatives, we can determine if these critical points correspond to a minimum or not.
Taking the partial derivative of f with respect to x, we get:
∂f/∂x = 12x³ - 2y
Taking the partial derivative of f with respect to y, we get:
∂f/∂y = 12y³ - 2x
Setting both of these equations equal to 0 and solving for x and y will give us the critical points. By evaluating the second-order partial derivatives, we can determine if these critical points correspond to a minimum, maximum, or saddle point. Finally, we substitute the values of x and y at the minimum point back into f to find the minimum value of f.

a) The value of the limit is -1/6.
b) The value of the limit is -1/3.
(a) To evaluate the limit using l'Hospital's Rule, we differentiate the numerator and denominator separately.
lim(x→0) (sin x - x) / x^3
Differentiating the numerator:
lim(x→0) (cos x - 1) / x^3
Differentiating the denominator:
lim(x→0) 3x^2
Now, let's re-evaluate the limit using the differentiated forms:
lim(x→0) (cos x - 1) / (3x^2)
To find the limit of this expression as x approaches 0, we can directly substitute x = 0:
lim(x→0) (cos 0 - 1) / (3(0)^2)
= (1 - 1) / 0
= 0 / 0
The result is an indeterminate form (0/0). To further evaluate the limit, we can apply l'Hospital's Rule again by differentiating the numerator and denominator.
Differentiating the numerator:
lim(x→0) (-sin x) / (6x)
Differentiating the denominator:
lim(x→0) 6
Now, let's re-evaluate the limit using the differentiated forms:
lim(x→0) (-sin x) / (6x)
Plugging in x = 0 directly, we get:
lim(x→0) (-sin 0) / (6(0))
= 0 / 0
We still have an indeterminate form. To proceed further, we can apply l'Hospital's Rule once more.
Differentiating the numerator:
lim(x→0) (-cos x) / 6
Differentiating the denominator:
lim(x→0) 0
Now, let's re-evaluate the limit using the differentiated forms:
lim(x→0) (-cos x) / 6
Substituting x = 0 directly:
lim(x→0) (-cos 0) / 6
= (-1) / 6
= -1/6
Therefore, the value of the limit is -1/6.
(b) To evaluate the second limit using l'Hospital's Rule, we differentiate the numerator and denominator separately.
lim(x→0) (x + e^x) / (3 - 6x + 1)
Differentiating the numerator:
lim(x→0) (1 + e^x) / (3 - 6x + 1)
Differentiating the denominator:
lim(x→0) -6
Now, let's re-evaluate the limit using the differentiated forms:
lim(x→0) (1 + e^x) / -6
Plugging in x = 0 directly, we get:
lim(x→0) (1 + e^0) / -6

Solve the separable differential equation dy dt t t²y + y Use the following initial condition: y(0) = 5. Write answer as a formula in the variable t.
The solution to the differential equation with the given initial condition is: y(t) = 5/t.
To solve the separable differential equation
dy/dt = t/(t²y) + y,
we can rearrange the terms as:
dy/y = t/(t²y) dt + dt
Integrating both sides, we get:
ln|y| = -ln|t| + ln|y| + C
Simplifying, we get:
ln|t| = C
Substituting the initial condition y(0) = 5, we get:
ln|5| = C
Therefore, C = ln|5|
Substituting back into the equation, we get:
ln|y| = -ln|t| + ln|y| + ln|5|
Simplifying, we get: ln|y| = ln|5/t|
Taking the exponential of both sides, we get:
|y| = e^(ln|5/t|)
Since y(0) = 5, we can determine the sign of y as positive. Therefore, we have: y = 5/t

Find the work done by F in moving a particle once counterclockwise around the given curve. = F= (3x - 5y)i + (5x – 3y); C: The circle (x-4)2 + (y – 4)2 = 16 = ... What is the work done in one counterclockwise circulation?
We are given a vector field F = (3x - 5y)i + (5x - 3y)j and a curve C defined by the equation (x-4)^2 + (y-4)^2 = 16. We need to find the work done by F in moving a particle once counterclockwise around the curve.
The work done by a vector field F in moving a particle along a curve is given by the line integral of F along that curve. In this case, we need to evaluate the line integral ∮F · dr, where dr is the differential displacement vector along the curve.
To calculate the line integral, we can parameterize the curve C. Since C is a circle centered at (4, 4) with radius 4, we can use the parameterization x = 4 + 4cos(t) and y = 4 + 4sin(t), where t ranges from 0 to 2π.
Next, we calculate dr as the differential displacement vector along the curve:
dr = dx i + dy j = (-4sin(t))i + (4cos(t))j.
Substituting the parameterization and dr into the line integral ∮F · dr, we have:
∮F · dr = ∫[F(x, y) · dr] = ∫[(3x - 5y)(-4sin(t)) + (5x - 3y)(4cos(t))] dt.
Evaluating this integral over the range 0 to 2π will give us the work done by F in moving a particle once counterclockwise around the curve C.
Note: The detailed calculation of the line integral involves substituting the parameterization and performing the integration. Due to the length and complexity of the calculation, it is not possible to provide the exact numerical value in this text-based format.

Prove whether or not the following series converges. Justify your answer tho using series tests. infinity summation k = 1(k+3/k)^k
"
Using the ratio test for the series ∑(k=1 to ∞) [(k+3)/k]^k, the series diverges. This is based on the ratio test, which shows that the limit of the absolute value of the ratio of consecutive terms is not less than 1, indicating that the series does not converge.
To determine whether the series ∑(k=1 to ∞) [(k+3)/k]^k converges or diverges, we can use 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. If the limit is greater than 1 or it does not exist, then the series diverges.
Let's apply the ratio test to the given series:
Let a_k = [(k+3)/k]^k
We calculate the ratio of consecutive terms:
|a_(k+1)/a_k| = |[((k+1)+3)/(k+1)]^(k+1) / [(k+3)/k]^k|
Simplifying this expression, we get:
|a_(k+1)/a_k| = |[(k+4)(k+1)/[(k+1)+3)] * [(k+3)/k]^k|
Now, let's take the limit of this ratio as k approaches infinity:
lim(k→∞) |a_(k+1)/a_k| = lim(k→∞) |[(k+4)(k+1)/[(k+1)+3)] * [(k+3)/k]^k|
Simplifying this limit expression, we find:
lim(k→∞) |a_(k+1)/a_k| = lim(k→∞) |(k+4)(k+1)/(k+4)(k+3)| * lim(k→∞) |(k+3)/k|^k
Notice that lim(k→∞) |(k+4)(k+1)/(k+4)(k+3)| = 1, which is less than 1.
Now, we focus on the second term:
lim(k→∞) |(k+3)/k|^k = lim(k→∞) [(k+3)/k]^k = e^3
Since e^3 is a constant and it is greater than 1, the limit of this term is not less than 1.
Therefore, we have:
lim(k→∞) |a_(k+1)/a_k| = 1 * e^3 = e^3
Since e^3 is greater than 1, the limit of the ratio of consecutive terms is not less than 1.
According to the ratio test, if the limit of the ratio of consecutive terms is not less than 1, the series diverges.
Hence, the series ∑(k=1 to ∞) [(k+3)/k]^k diverges.

1. Consider the relation R on the set A = {0, 1, 2, 3, 4}, defined by: == aRb a=bc and b=ad, for some c, d E A. = (a) Is R an equivalence relation on A? If so, prove it. If not, show why not. (b) Is R
Since a = 1 cannot be written in the form bc for any c E A. Therefore, R is not transitive and hence, not an equivalence relation on A.
(a) Yes, R is an equivalence relation on A.The relation R is an equivalence relation if it satisfies the following properties:
Reflexive: Each element of A is related to itself.i.e. aRa for all a E A.Each element a of A can be written in the form a = bc and b = ad for some c, d E A, then aRa, since a = bc = adc = dbc, and thus aRa.Symmetric: If a is related to b, then b is related to a.i.e., if aRb, then bRa.
Transitive: If a is related to b and b is related to c, then a is related to c.i.e., if aRb and bRc, then aRc.Suppose aRb and bRc, then there exists c, d, e, and f such that:a = bd,b = ae, and c = bf.
Then, a = b(d) = a(e)(d) = c(e)(d), so aRc. Hence, R is an equivalence relation.(b) R is not an equivalence relation on A.
This is because the relation R is not transitive.
Suppose a = 1, b = 2, and c = 3.
Then, aRb since a = bc with c = 2. Similarly, bRc since b = ad with d = 3.
However, a is not related to c, since a = 1 cannot be written in the form bc for any c E A. Therefore, R is not transitive and hence, not an equivalence relation on A.

(a) The series Σ(n = 0 to ∞) (3η)! is divergent. This can be determined using the ratio test. The series (3η)! diverges, and the ratio test is used to establish this.
To determine the convergence or divergence of the series Σ(n = 0 to ∞) (3η)!, we can apply the ratio test. The ratio test states that if the limit of the absolute value of the ratio of consecutive terms is greater than 1, the series diverges. Alternatively, if the limit is less than 1, the series converges.
Let's apply the ratio test to the series (3η)!:
lim(n→∞) |((3η + 1)!)/(3η)!| = lim(n→∞) (3η + 1)
Since the limit of (3η + 1) as n approaches infinity is infinity, the ratio test fails to yield a conclusive result. Therefore, we cannot determine the convergence or divergence of the series (3η)! using the ratio test.
(b) The series Σ(n = 1 to ∞) sin^(-1)(αξ) also diverges. The divergence test can be used to establish this.
The series Σ(n = 1 to ∞) sin^(-1)(αξ) diverges, and the divergence test is employed to determine this.
To determine the convergence or divergence of the series Σ(n = 1 to ∞) sin^(-1)(αξ), we can use the divergence test. The divergence test states that if the limit of the series terms as n approaches infinity is not equal to zero, then the series diverges.
Let's apply the divergence test to the series Σ(n = 1 to ∞) sin^(-1)(αξ):
lim(n→∞) sin^(-1)(αξ) ≠ 0

a. The exact coordinates of these points (-12.25, -26) and (-12.25, -26).
b. The approximate area of the region enclosed by the curves y = 72 + 8x and y = -26 is 416.282
a. To find the points of intersection between the curves y = 72 + 8x and y = -26, we can set the equations equal to each other:
72 + 8x = -26
Subtract 72 from both sides:
8x = -98
Divide by 8:
x = -12.25
Now we can substitute this value back into either equation to find the corresponding y-coordinate. Let's use the first equation:
y = 72 + 8(-12.25)
y = 72 - 98
y = -26
Therefore, the points of intersection are (-12.25, -26) and (-12.25, -26).
b. To find the area of the region enclosed by these two curves, we need to find the integral of the difference between the curves with respect to x.
We integrate from x = -12.25 to x = 1.1:
Area = ∫[from -12.25 to 1.1] [(72 + 8x) - (-26)] dx
Simplifying:
Area = ∫[from -12.25 to 1.1] (98 + 8x) dx
Area = [49x + 4x^2] evaluated from -12.25 to 1.1
Area = [(49(1.1) + 4(1.1)^2) - (49(-12.25) + 4(-12.25)^2)]
Calculating:
Area ≈ 416.282
Therefore, the approximate area of the region enclosed by the curves y = 72 + 8x and y = -26 is 416.282 (rounded to three decimal places).

Set up the definite integral required to find the area of the region between the graph of y = 15 – x² and Y 27x + 177 over the interval - 5 ≤ x ≤ 1. = dx 0
The area of the region between the two curves is 667 square units.
To find the area of the region between the graphs of \(y = 15 - x^2\) and \(y = 27x + 177\) over the interval \(-5 \leq x \leq 1\), we need to set up the definite integral.
The area can be calculated by taking the difference between the upper and lower curves and integrating with respect to \(x\) over the given interval.
First, we find the points of intersection between the two curves by setting them equal to each other:
\(15 - x^2 = 27x + 177\)
Rearranging the equation:
\(x^2 + 27x - 162 = 0\)
Solving this quadratic equation, we find the two intersection points: \(x = -18\) and \(x = 9\).
Next, we set up the definite integral for the area:
\(\text{Area} = \int_{-5}^{1} \left[(27x + 177) - (15 - x^2)\right] \, dx\)
Simplifying:
\(\text{Area} = \int_{-5}^{1} (27x + x^2 + 162) \, dx\)
Now, we can integrate term by term:
\(\text{Area} = \left[\frac{27x^2}{2} + \frac{x^3}{3} + 162x\right]_{-5}^{1}\)
Evaluating the definite integral:
\(\text{Area} = \left[\frac{27(1)^2}{2} + \frac{(1)^3}{3} + 162(1)\right] - \left[\frac{27(-5)^2}{2} + \frac{(-5)^3}{3} + 162(-5)\right]\)
Simplifying further:
\(\text{Area} = \frac{27}{2} + \frac{1}{3} + 162 + \frac{27(25)}{2} - \frac{125}{3} - 162(5)\)
Finally, calculating the value:
\(\text{Area} = \frac{27}{2} + \frac{1}{3} + 162 + \frac{675}{2} - \frac{125}{3} - 810\)
\(\text{Area} = \frac{27}{2} + \frac{1}{3} + \frac{486}{3} + \frac{675}{2} - \frac{125}{3} - \frac{2430}{3}\)
\(\text{Area} = \frac{900}{6} + \frac{2}{6} + \frac{2430}{6} + \frac{1350}{6} - \frac{250}{6} - \frac{2430}{6}\)
(\text{Area} = \frac{900 + 2 + 2430 + 1350 - 250 - 2430}{6}\)
(\text{Area} = \frac{4002}{6}\)
(\text{Area} = 667\) square units
Therefore, the area of the region between the two curves is 667 square units.

To determine the arc length of a sector, we need to consider the given information for each case:
Given the radius of 14 cm, we need to find the central angle in radians. The arc length formula is s = rθ, where s represents the arc length, r is the radius, and θ is the central angle in radians.
To find the arc length, we can multiply the radius (14 cm) by the central angle in radians. Given the diameter of 18 ft, we can calculate the radius by dividing the diameter by 2. Then, we can use the same formula s = rθ, where r is the radius and θ is the central angle in radians.
The arc length can be found by multiplying the radius by the central angle in radians. Given the diameter of 7.5 meters and a central angle of 120°, we can first find the radius by dividing the diameter by 2.
Then, we need to convert the central angle from degrees to radians by multiplying it by π/180. Using the formula s = rθ, we can calculate the arc length by multiplying the radius by the central angle in radians.
Given the diameter, we need more specific information about the central angle in order to calculate the arc length.
In summary, to determine the arc length of a sector, we use the formula s = rθ, where s is the arc length, r is the radius, and θ is the central angle in radians.

The most helpful substitution for evaluating the given integral is option A: x = 14sinθ.
:
To evaluate the integral ∫dx/(196 - x^2)^2, we can use the trigonometric substitution x = 14sinθ. This substitution is effective because it allows us to express (196 - x^2) and dx in terms of trigonometric functions.
To find dx, we differentiate both sides of the substitution x = 14sinθ with respect to θ:
dx/dθ = 14cosθ
Rearranging the equation, we can solve for dx:
dx = 14cosθ dθ
Now, substitute x = 14sinθ and dx = 14cosθ dθ into the original integral:
∫dx/(196 - x^2)^2 = ∫(14cosθ)/(196 - (14sinθ)^2)^2 * 14cosθ dθ
Simplifying the expression under the square root and combining the constants, we have:
= ∫196cosθ/(196 - 196sin^2θ)^2 * 14cosθ dθ
= ∫196cosθ/(196 - 196sin^2θ)^2 * 14cosθ dθ
= 196 * 14 ∫cos^2θ/(196 - 196sin^2θ)^2 dθ

(a) For the function r(t) = 4t + 1.8 + 3, to find the tangent (T), normal (N), and binormal (B) vectors at t = 1, we need to calculate the first derivative (velocity vector), second derivative (acceleration vector), and cross product of the velocity and acceleration vectors.
However, since the function provided does not contain information about the direction or orientation of the curve, it is not possible to determine the exact values of T, N, and B at t = 1 without additional information.
(b) For the function r(t) = (1, 2√t), we can find the tangent (T), normal (N), and binormal (B) vectors at t = 1 by calculating the derivatives and normalizing the vectors. The first derivative is r'(t) = (0, 1/√t), which gives the velocity vector. The second derivative is r''(t) = (0, -1/2t^(3/2)), representing the acceleration vector. Evaluating these derivatives at t = 1, we get r'(1) = (0, 1) and r''(1) = (0, -1/2). The tangent vector T is the normalized velocity vector: T = r'(1) / ||r'(1)|| = (0, 1) / 1 = (0, 1). The normal vector N is the normalized acceleration vector: N = r''(1) / ||r''(1)|| = (0, -1/2) / (1/2) = (0, -1). The binormal vector B is the cross product of T and N: B = T x N = (0, 1) x (0, -1) = (1, 0).
(c) For the function r(t) = (31, 21, 1), the position is constant, so the velocity, acceleration, and their cross product are all zero. Therefore, at any value of t, the tangent (T), normal (N), and binormal (B) vectors are undefined.

Substituting [tex]\(x = 2\)[/tex], we get [tex]\(h'(2) = 3[g(2)]^2 \cdot g'(2)\).[/tex]
Using the given values in the table, [tex]\(g(2) = 8\) \\[/tex] and [tex]\(g'(2) = 3\)[/tex], so[tex]\(h'(2) = 3(8)^2 \cdot 3 = 3 \cdot 64 \cdot 3 = 576\)[/tex].

The power rule states that if we have a function [tex]\(j(x) = x^n\), then \(j'(x) = n \cdot x^{n-1}\)[/tex].
In this case, [tex]\(j(x) = x + 2\)[/tex], which can be rewritten as [tex]\(j(x) = x^1 + 2\)\\[/tex].

What is the differentiation of a function?
The differentiation of a function refers to the process of finding its derivative. The derivative of a function states the rate at which the function changes with respect to its independent variable.
The derivative of a function f(x) with respect to the variable x is denoted as f'(x) or [tex]\frac{df}{dx}[/tex].
To differentiate the function [tex]g(t) = \frac{ln(t(t^2 + 1)^4}{5(8t - 1)}[/tex], we can apply the quotient rule and simplify the expression. Let's go through the steps:
Step 1: Apply the quotient rule to differentiate the function:
Let, [tex]f(t) = ln(t(t^2 + 1)^4)[/tex] and h(t) = 5(8t - 1).
The quotient rule states:

Step 2: Compute the derivatives:
Using the chain rule and the power rule, we can find the derivatives of f(t) and g(t) as follows:
[tex]f(t) = ln(t(t^2 + 1)^4)\\ f'(t) = \frac{1}{t(t^2 + 1)^4)} * (t(t^2 + 1)^4)'\\f'(t) =\frac{1 }{(t(t^2 + 1)^4} * (t * 4(t^2 + 1)^32t+ (t^2 + 1)^4 * 1) \\f'(t)=\frac{8t}{t^2+1}+\frac{1}{t}\\[/tex]
h(t) =5(8t-1)
h'(t) = 5 * 8
h'(t) = 40
Step 3: Substitute the derivatives into the quotient rule expression:
[tex]g(t) = \frac{ln(t(t^2 + 1)^4}{5(8t - 1)}[/tex] =[tex]\frac{ h(t) * f'(t) - f(t) * h'(t)}{ (h(t))^2}[/tex] =[tex]\frac{5(8t - 1)*(\frac{8t}{t^2+1}+\frac{1}{t})-ln(t(t^2+1)^4)*40}{(5(8-1))^2}\\[/tex]
Therefore, the differentiation of [tex]g(t) = \frac{ln(t(t^2 + 1)^4}{5(8t - 1)}[/tex] is:
[tex]\frac{d}{dt} (\frac{ln(t(t^2 + 1)^4} {5(8t - 1)})[/tex] =[tex]\frac{5(8t - 1)*(\frac{8t}{t^2+1}+\frac{1}{t})-ln(t(t^2+1)^4)*40}{(5(8-1))^2}\\[/tex]

What is series for convergence or divergence?
The term "convergent series" refers to a series whose partial sums tend to a limit. A divergent series is one whose partial sums, in contrast, do not approach a limit. The Divergent series often reach, reach, or don't reach a particular number.
As given series is,
-(2/3) + (4/4) - (6/5) + (8/6) - (10/7) + ...
Assume b₁ = (-2/3), b₂ = (4/4), b₃ = (-6/5), b₄ = (8/6), and b₅ = (-10/7).
Since mod-bi < mod-b(i + 1) for all i implies that mode of the series.
(a). Evaluate the value of bₙ:
From given series,
-(2/3) + (4/4) - (6/5) + (8/6) - (10/7) + ...
Then, b₁ = (-2/3), b₂ = (4/4), b₃ = (-6/5), b₄ = (8/6), and b₅ = (-10/7).
So, bₙ = alpha ∑ (n = 1) {(-1)ⁿ 2n) / (n + 2)}
Thus, bₙ = {(-1)ⁿ 2n) / (n + 2)}.
(b). Evaluate the value of Limit:
lim (n = alpha) mod- bₙ = lim (n = alpha) {(2n) / (n + 2)}
= lim (n = alpha) {(2n) / n(1 + 2/n)}
= 2
Since, lim (n = alpha) bₙ = 2.
Hence, the values of all sub-parts have been obtained.
