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.

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.

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.

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).

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

= (1 + 1) / -6

= 2 / -6

= -1/3

Therefore, the value of the limit is -1/3.

The value of f(g(3)) is 14.

To find the value of f(g(3)), we need to evaluate the functions g(3) and then substitute the result into the function f.

First, let's find the value of g(3):

g(3) = 2(3) + 1 = 6 + 1 = 7.

Now that we have g(3) = 7, we can substitute it into the function f:

f(g(3)) = f(7).

To find the value of f(7), we need to substitute 7 into the function f:

f(7) = 3(7) - 7 = 21 - 7 = 14.

Therefore, the value of f(g(3)) is 14.

Given the functions f(x) = 3x - 7 and g(x) = 2x + 1, we are asked to find the value of f(g(3)).

To evaluate f(g(3)), we start by evaluating g(3). Since g(x) is a linear function, we can substitute 3 into the function to get g(3):

g(3) = 2(3) + 1 = 6 + 1 = 7.

Next, we substitute the value of g(3) into the function f. Using the expression f(x) = 3x - 7, we substitute x with 7:

f(g(3)) = f(7) = 3(7) - 7 = 21 - 7 = 14.

Therefore, the value of f(g(3)) is 14.

In summary, to find the value of f(g(3)), we first evaluate g(3) by substituting 3 into the function g(x) = 2x + 1, which gives us 7. Then, we substitute the value of g(3) into the function f(x) = 3x - 7 to find the final result of 14.

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.

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.

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,

Given that [tex]\(g(x)\)[/tex] and [tex]\(g'(x)\)[/tex] are differentiable, we can use the chain rule.

The chain rule states that if we have a composite function [tex]\(h(x) = f(g(x))\)[/tex], then [tex]\(h'(x) = f'(g(x)) \cdot g'(x)\)[/tex].

In this case, [tex]\(h(x) = [g(x)]^3\)[/tex], so [tex]\(f(u) = u^3\)[/tex] where [tex]\(u = g(x)\).[/tex]

To solve the given integral expression, we will evaluate each integral separately and then subtract the results.

Integral 1 can be evaluated as follows:

[tex]\(\int (x^4 - x^2 + 2e^x) \, dx\)[/tex]

To find the antiderivative of each term, we apply the power rule and the rule for integrating [tex]\(e^x\)[/tex]:

[tex]\(\int x^4 \, dx = \frac{x^5}{5} + C_1\)\\\(\int -x^2 \, dx = -\frac{x^3}{3} + C_2\)\\\(\int 2e^x \, dx = 2e^x + C_3\)[/tex]

Therefore, the result of the first integral is:

[tex]\(\int (x^4 - x^2 + 2e^x) \, dx = \frac{x^5}{5} - \frac{x^3}{3} + 2e^x + C_1\)[/tex]

Integral 2 can be evaluated as follows:

[tex]\(\int (x^5 - 2x^2e^x) \, dx\)[/tex]

Using the power rule and the rule for integrating [tex]\(e^x\)[/tex], we have:

[tex]\(\int x^5 \, dx = \frac{x^6}{6} + C_4\)\\\(\int -2x^2e^x \, dx = -2e^x(x^2 - 2x + 2) + C_5\)[/tex]

Thus, the result of the second integral is:

[tex]\(\int (x^5 - 2x^2e^x) \, dx = \frac{x^6}{6} - 2e^x(x^2 - 2x + 2) + C_5\)[/tex]

Now, we can subtract the second integral from the first to get the final value:

[tex]\[\int (x^4 - x^2 + 2e^x) \, dx - \int (x^5 - 2x^2e^x) \, dx = \left(\frac{x^5}{5} - \frac{x^3}{3} + 2e^x + C_1\right) - \left(\frac{x^6}{6} - 2e^x(x^2 - 2x + 2) + C_5\right)\][/tex]

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.

Option A, with side measurements of 6, 7, and 8, is not a right triangle because it does not satisfy the Pythagorean theorem. The other options (B, C, and D) are right triangles since their side measurements satisfy the Pythagorean theorem.

To determine which triangle is not a right triangle, we need to check if the given side measurements satisfy the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

Let's calculate the values for each option:

A) Using the Pythagorean theorem: 6^2 + 7^2 = 36 + 49 = 85

Since 85 is not equal to 8^2 (64), option A is not a right triangle.

B) Using the Pythagorean theorem: 3^2 + 4^2 = 9 + 16 = 25

Since 25 is equal to 5^2 (25), option B is a right triangle.

C) Using the Pythagorean theorem: 9^2 + 40^2 = 81 + 1600 = 1681

Since 1681 is equal to 41^2 (1681), option C is a right triangle.

D) Using the Pythagorean theorem: 16^2 + 30^2 = 256 + 900 = 1156

Since 1156 is equal to 34^2 (1156), option D is a right triangle.

Based on the calculations, we can conclude that option A, with side measurements of 6, 7, and 8, is not a right triangle because it does not satisfy the Pythagorean theorem. The other options (B, C, and D) are right triangles since their side measurements satisfy the Pythagorean theorem.

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:

[tex]\frac{d}{dt} [\frac{f(t)}{ h(t)}] =\frac{ h(t) * f'(t) - f(t) * h'(t)}{ (h(t))^2}[/tex]

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]

[tex]f(x) = 6x - 18x^3 + \frac{216x^5}{4} - \frac{1944x^7}{6} + ...[/tex]

To find the Maclaurin series of the function f(x) = 6x cos(6x), we can start by expanding the cosine function as a power series. The Maclaurin series expansion -

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

Substituting 6x in place of x, we have:

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

Simplifying the powers of 6x, we get:

cos(6x) = [tex]1 - \frac{36x^2}{2! }+ \frac{1296x^4}{4! }- \frac{46656x^6}{6!} + ...[/tex]

Now, multiply this series by 6x to obtain the Maclaurin series for f(x):

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

Thus, the solution to the differential equation with the given initial condition is: y(t) = 5/t.

The region bounded by the x-axis, the lines x = -3 and x = 0, and the function y = f(x) = (x+3)2 can be calculated using the limit of sums approach.

On the x-axis, we define small subintervals of width x between [-3, 0]. In the event that there are n subintervals, then x = (0 - (-3))/n = 3/n.

Rectangles within each subinterval can be used to roughly represent the area under the curve. Each rectangle has a height determined by the function f(x) and a width of x.

The area of each rectangle is f(x) * x = (x+3)2 * (3/n).

The equation of the plane that contains the line [tex]x = 1 + 2t, y = t, z = 9 - t,[/tex]and is parallel to the plane [tex]2x + 4y + 8z = 17[/tex] is [tex]2x + 4y + 8z = 11[/tex].

To find the equation of the plane, we first need to determine the direction vector of the line that lies in the plane.

From the given line equations, we can see that the direction vector is given by the coefficients of t in each component: (2, 1, -1).

Since the plane we want to find is parallel to the plane [tex]2x + 4y + 8z = 17[/tex], the normal vector of the plane we seek will be the same as the normal vector of the given plane. Therefore, the normal vector of the plane is (2, 4, 8).

To find the equation of the plane, we can use the point-normal form of the equation of a plane.

Since the plane contains the point (1, 0, 9) (which corresponds to t = 0 in the line equations), we can substitute these values into the point-normal form equation:

[tex]2(x - 1) + 4(y - 0) + 8(z - 9) = 0[/tex]

Simplifying the equation, we get:

[tex]2x + 4y + 8z = 11[/tex]

Hence, the equation of the plane that contains the given line and is parallel to the plane [tex]2x + 4y + 8z = 17[/tex] is [tex]2x + 4y + 8z = 11.[/tex]

In the given task, we need to find an equation of a plane that is parallel to another plane and also contains a given line. The first step is to understand that two parallel planes have the same normal vector. The equation of the plane 2x + 4y + 8z = 17, has a normal vector of (2,4,8). Our unknown plane parallel to this would also have this normal vector.

Then we need to find a point that lies on the plane containing the line. This can be any point on the line. So if we set t=0 in the line equation, we get the point (1,0,9) which also lie on the plane.

The equation of a plane given point (x0, y0, z0) and normal vector (a, b, c) is a(x - x0) + b(y - y0) + c(z - z0) = 0. So, if we plug our values, we get 2(x - 1) + 4(y - 0) + 8(z - 9) = 0, simplifying gives us 2x + 4y + 8z = 18 is the equation of the required plane.

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

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

Both series (a) Σ(n = 0 to ∞) (3η)! and (b) Σ(n = 1 to ∞) sin^(-1)(αξ) are divergent. The ratio test was used to determine the divergence of (3η)!, while the divergence test was used to establish the divergence of sin^(-1)(αξ).

(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

Since the limit of sin^(-1)(αξ) as n approaches infinity is not equal to zero, the series Σ(n = 1 to ∞) sin^(-1)(αξ) diverges.
