Consider the function y = log, X. a. Make a table of approximate values and graph the function - -5 b. What are the domain, range, x-intercept, and asymptote? c. What is the end behavior of the gra

a. The vectors ü, 5ū, and -5ū are related in terms of magnitude and direction. The vectors 5ū and -5ū have the same magnitude as ü but differ in direction.

Specifically, the vector 5ū is in the same direction as ü, while -5ū is in the opposite direction. Both 5ū and -5ū are scalar multiples of the vector ü, with the scalar being 5 and -5 respectively.

In vector algebra, multiplying a vector by a scalar result in a new vector with the same direction as the original vector but with a different magnitude. When we multiply the vector ü by 5, we obtain a new vector 5ū with a magnitude five times greater than ü.

The direction of 5ū remains the same as that of ü. On the other hand, multiplying ü by -5 gives us a new vector -5ū, which has the same magnitude as ü but points in the opposite direction.

b. No, it is not possible for the sum of 3 parallel vectors to be equal to the zero vector, except when all three vectors have zero magnitude.

Parallel vectors have the same or opposite direction but can have different magnitudes. When adding vectors, the resultant vector is determined by the vector's magnitude and direction.

In the case of parallel vectors, their magnitudes add up, resulting in a vector with a magnitude equal to the sum of the magnitudes of the individual vectors.

Since the zero vector has zero magnitude, the sum of three non-zero parallel vectors will always have a non-zero magnitude. However, if all three parallel vectors have zero magnitude, their sum will also be the zero vector since adding zero vectors does not change their magnitude or direction.

The given series is convergent. To determine whether the series is convergent or divergent, we need to examine the behavior of its terms as n approaches infinity. The given series is a sum of two terms: 1/9 and e^(-n).

The term 1/9 is a constant term that does not depend on n. The series ∑(1/9) is a geometric series with a common ratio of 1, which is less than 1. Therefore, this series converges, and its sum can be found using the formula for the sum of a geometric series:

Sum = a / (1 - r),

where a is the first term and r is the common ratio. In this case, a = 1/9 and r = 1, so the sum of the series ∑(1/9) is given by:

Sum = (1/9) / (1 - 1) = (1/9) / 0.

However, dividing by zero is undefined, so the sum of the series ∑(1/9) is not defined.

The second term in the series is e^(-n), where e is Euler's number. As n approaches infinity, e^(-n) approaches 0. This term contributes to the convergence of the series. Therefore, the series ∑(1/9 + e^(-n)) is convergent. However, since the first term does not have a defined sum, we cannot determine the sum of the series.

Answer:

True, making multiplication a game can motivate children to learn.

The approximation for f'(9.4) is approximately 8.2. To find the differential dy when x = 1 and dx = 0.3, we can use the formula for the differential: dy = f'(x) * dx.

First, we need to find the derivative of the function y = 5x^2 + 6x + 2. Taking the derivative, we have: y' = 10x + 6. Now we can substitute the values x = 1 and dx = 0.3 into the formula for the differential: dy = (10x + 6) * dx = (10 * 1 + 6) * 0.3 = 4.8. Therefore, the differential dy when x = 1 and dx = 0.3 is dy = 4.8.

Similarly, to find the differential dy when x = 1 and dx = 0.6, we can substitute these values into the formula: dy = (10x + 6) * dx= (10 * 1 + 6) * 0.6= 9.6. Thus, the differential dy when x = 1 and dx = 0.6 is dy = 9.6. To approximate f'(9.4), we can use the given information that f(9.4) = 0.6 and f(9.9) = 4.7. We can use the average rate of change to approximate the derivative: f'(9.4) ≈ (f(9.9) - f(9.4)) / (9.9 - 9.4)= (4.7 - 0.6) / 0.5= 8.2. Therefore, the approximation for f'(9.4) is approximately 8.2.

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)}

The original integral becomes:

∫ (2x + 5) / (x^2 - x - 2) dx = 3 ln|x - 2| - ln|x + 1| + C

where C is the constant of integration. So, the evaluated integral is 3 ln|x - 2| - ln|x + 1| + C.

To evaluate the integral ∫ (2x + 5) / (x^2 - x - 2) dx, we can start by factoring the denominator.

The denominator can be factored as (x - 2)(x + 1):

∫ (2x + 5) / (x^2 - x - 2) dx = ∫ (2x + 5) / [(x - 2)(x + 1)] dx

Now, we can use partial fraction decomposition to break the fraction into simpler fractions. We express the fraction as:

(2x + 5) / [(x - 2)(x + 1)] = A / (x - 2) + B / (x + 1)

Multiplying both sides by (x - 2)(x + 1), we get:

2x + 5 = A(x + 1) + B(x - 2)

Expanding and collecting like terms, we have:

2x + 5 = (A + B)x + (A - 2B)

Comparing coefficients, we find:

A + B = 2   (coefficients of x on both sides)

A - 2B = 5   (constant terms on both sides)

Solving this system of equations, we find A = 3 and B = -1.

Now, we can rewrite the integral using the partial fraction decomposition:

∫ (2x + 5) / [(x - 2)(x + 1)] dx = ∫ [3/(x - 2) - 1/(x + 1)] dx

Integrating each term separately, we get:

∫ 3/(x - 2) dx - ∫ 1/(x + 1) dx

The integral of 3/(x - 2) can be evaluated as ln|x - 2|, and the integral of 1/(x + 1) can be evaluated as ln|x + 1|.

Therefore, the original integral becomes:

∫ (2x + 5) / (x^2 - x - 2) dx = 3 ln|x - 2| - ln|x + 1| + C

where C is the constant of integration.

So, the evaluated integral is 3 ln|x - 2| - ln|x + 1| + C.

The integral represents the volume of the solid obtained by rotating the region bounded by the curves y = sin(x), y = 0, x = 0, and x = π/2 about the y-axis.

To find the volume of the solid, we can use the method of cylindrical shells. Since we are rotating the region bounded by the curves y = sin(x), y = 0, x = 0, and x = π/2 about the y-axis, each cross section of the solid will be a cylindrical shell with thickness dy and radius x.

The volume of a single cylindrical shell is given by the formula V = 2πx * h * dy, where x represents the radius and h represents the height of the shell.

The height of each shell can be represented as h = f(x) - g(x), where f(x) is the upper curve (y = sin(x)) and g(x) is the lower curve (y = 0). In this case, h = sin(x) - 0 = sin(x).

Substituting x = x(y) into the formula for the volume of a cylindrical shell, we have V = 2πx(y) * sin(x) * dy.

To determine the limits of integration for y, we need to find the range of y-values that correspond to the region bounded by y = sin(x), y = 0, x = 0, and x = π/2. In this case, the limits of integration are y = 0 to y = 1.

Now, we can set up the integral for the volume:

The particular solution to the given differential equation is:[tex]y_p(t) = (e^t/t) * t * exp(t)[/tex]

What is differential equation?

A differential equation is a mathematical equation that relates a function to its derivatives. It involves the derivatives of an unknown function and can describe various phenomena and relationships in mathematics, physics, engineering, and other fields.

To find a particular solution to the given differential equation, we can assume a particular form for y(t) and then determine the values of the coefficients. Let's assume a particular solution of the form:

[tex]y_p(t) = A * t * exp(t)[/tex]

where A is a constant coefficient that we need to determine.

Now, we'll differentiate [tex]y_p(t)[/tex] twice with respect to t:

[tex]y_p'(t) = A * (1 + t) * exp(t)\\\\y_p''(t) = A * (2 + 2t + t**2) * exp(t)[/tex]

Next, we substitute these derivatives into the original differential equation:

[tex]y_p''(t) - 2 * y_p'(t) + y_p(t) = e^t/t[/tex]

[tex]A * (2 + 2t + t**2) * exp(t) - 2 * A * (1 + t) * exp(t) + A * t * exp(t) = e^t/t[/tex]

Simplifying and canceling out the common factor of exp(t), we have:

[tex]A * (2 + 2t + t**2 - 2 - 2t + t) = e^t/t[/tex]

[tex]A * (t**2 + t) = e^t/t[/tex]

To solve for A, we divide both sides by (t**2 + t):

[tex]A = e^t/t / (t**2 + t)[/tex]

Therefore, the particular solution to the given differential equation is:

[tex]y_p(t) = (e^t/t) * t * exp(t)[/tex]

Simplifying further, we get:

The derivative of the function f(x) = e × ln(11x) - eˣ + log(6x²), we can apply the rules of differentiation.

f(x) = e × ln(11x) - eˣ + log(6x²)

To differentiate the function, we use the following rules

1. The derivative of eˣ is eˣ.

2. The derivative of ln(u) is (1/u) × us, where u' is the derivative of u.

3. The derivative of log(u) is (1/u) × us, where u' is the derivative of u.

4. The derivative of a constant multiplied by a function is equal to the constant multiplied by the derivative of the function.

5. The derivative of the sum of functions is equal to the sum of their derivatives.

Now, let's differentiate each term of the function:

F(x) = e × (1/(11x)) × (11) - eˣ + (1/(6x²)) × (2x)

Simplifying, we get:

F(x) = e/ x - eˣ + 2/(3x)

To find f'(3), we substitute x = 3 into the derivative

of(3) = e/3 - e³ + 2/(3×3)

f'(3) = -18.95722

Reason: We differentiate the function f(x) to find its derivative, which represents the rate of change of the function at any given point. Evaluating the derivative at x = 3, denoted as F'(3), gives us the slope of the tangent line to the graph of f(x) at x = 3.

Reflections fix the shape or form and reverse the orientation of objects. In other words, they preserve the shape of an object but change its orientation.

Reflections fix the shape or form of an object because the distances between any two points on the object and their images under the reflection remain the same. For example, if we reflect a square across a line, the resulting image is still a square with the same side lengths as the original.

However, reflections reverse the orientation of objects. This means that if an object is reflected, its right side becomes its left side, and vice versa. For instance, if we reflect an uppercase letter 'A' across a line, the resulting image is a mirror image of 'A' with the orientation flipped.

The volume V can be calculated using the formula:

V = [tex]∫[a to b] π[R(x)^2 - r(x)^2] dx[/tex],

where R(x) is the outer radius and r(x) is the inner radius.

In this case, the outer radius R(x) is given by the top equation: R(x) = 2cos(θ) - 2,

and the inner radius r(x) is given by the bottom equation: r(x) = -9.

Since the given equations are in terms of θ, we need to express them in terms of x. Let's do the conversion:

For the top equation: y = 2cos(θ) - 2,

we can rewrite it as x = 2cos(θ) - 2, and solving for cos(θ) gives cos(θ) = (x + 2) / 2.

Substituting this into the equation, we get [tex]R(x) = 2[(x + 2) / 2] - 2 = x[/tex].

To compute the limit lim x→0 (1 - cos(2x)) without using l'Hopital, we can use a trigonometric identity and simplify the expression to (2sin²(x)).

By substituting this into sin(x²), we obtain the simplified limit of lim x→0 (2sin²(x²)).

To find the limit lim x→0 (1 - cos(2x)), we can use the trigonometric identity 1 - cos(2θ) = 2sin²(θ). By applying this identity, the expression becomes 2sin²(x).

Now, let's consider the limit of sin(x²) as x approaches 0. Since sin(x) is an odd function, sin(-x) = -sin(x), and therefore, sin(x²) = sin((-x)²) = sin(x²). Hence, we can rewrite the limit as lim x→0 (2sin²(x²)).

Next, we can expand sin²(x²) using the double-angle formula for sine: sin²(θ) = (1 - cos(2θ))/2. In this case, θ is x². Applying the double-angle formula, we get sin²(x²) = (1 - cos(2x²))/2.

Finally, substituting this back into the limit, we have lim x→0 [(2(1 - cos(2x²)))/2] = lim x→0 (1 - cos(2x²)).

Therefore, without using l'Hopital, we have simplified the original limit to lim x→0 (2sin²(x²)).

A) To verify that [tex]y_1 = r^2[/tex] and [tex]y_2 = z_o[/tex] satisfy the homogeneous form of the differential equation (a'y" - 6xy' + 10y = 0), we need to substitute these functions into the equation and check if the equation holds.

Given differential equation: zy" - 6xy' + 10y = 3.24 + 62%

Homogeneous form: a'y" - 6xy' + 10y = 0

Substituting  [tex]y_1 = r^2[/tex] and [tex]y_2 = z_o[/tex]  into the homogeneous form:

For  [tex]y_1 = r^2[/tex] :

a'([tex]r^2[/tex])'' - 6x([tex]r^2[/tex])' + 10([tex]r^2[/tex]) = 0

a'(2r) - 6x(2r) + 10([tex]r^2[/tex]) = 0

2a'r - 12xr + 10[tex]r^2[/tex] = 0

For y2 = zo:

a'([tex]z_o[/tex])'' - 6x([tex]z_o[/tex])' + 10([tex]z_o[/tex]) = 0

a'(0) - 6x(0) + 10[tex]z_o[/tex] = 0

10[tex]z_o[/tex] = 0

Since 10[tex]z_o[/tex] = 0, it satisfies the homogeneous form.

Therefore, both [tex]y_1 = r^2[/tex] and [tex]y_2 = z_o[/tex]  satisfy the homogeneous form of the differential equation.

B) To solve the given non-homogeneous differential equation using variation of parameters, we assume the particular solution as

The particular solution is given by:

[tex]y_{p(x)} = u_1(x)y_1 + u_2(x)y_2[/tex]

Taking derivatives:

[tex]y_{p'(x)} = u_1'(x)y_1 + u_2'(x)y_2 + u_1(x)y_1' + u_2(x)y_2'[/tex]

[tex]y_{p''(x)} = u_1''(x)y_1 + u_2''(x)y_2 + 2u_1'(x)y_1' + 2u_2'(x)y_2' + u_1(x)y_1'' + u_2(x)y_2''[/tex]

Substituting these derivatives into the original non-homogeneous equation:

[tex]z(y_1u_1'' + y_2u_2'') + 2z(y_1'u_1' + y_2'u_2') + z(y_1u_1 + y_2u_2) - 6x(y_1'u_1 + y_2'u_2) + 10(y_1u_1 + y_2u_2) = 3.24 + 62\%[/tex]

The Mean Value Theorem(MVT) does not apply to the function f(x) = √x - 2 on the interval [1, 9] because this function is not continuous on [1, 9].

The Mean Value Theorem states that if a function is continuous on a closed interval [a, b] and differentiable on the open interval (a, b), then there exists at least one point c in (a, b) where the derivative of the function is equal to the average rate of change of the function over the interval [a, b].

In this case, the function f(x) = √x - 2 is not continuous on the interval [1, 9]. The square root function √x is not defined for negative values of x, and since the interval [1, 9] includes the point x = 0, the function is not defined at that point. Therefore, the function is not continuous on the interval [1, 9], and as a result, the Mean Value Theorem does not apply.

For the Mean Value Theorem(MVT) to be applicable, it is necessary for the function to satisfy the conditions of continuity and differentiability on the given interval. Since f(x) = √x - 2 is not continuous at x = 0, it fails to meet the conditions required by the Mean Value Theorem. Consequently, we cannot apply the theorem to make any conclusions about the existence of a point where the derivative of the function equals the average rate of change on the interval [1, 9].

Let's assume that the length of the rectangular enclosure is L and the width is W. The side along the wall requires no fence, so we only need to fence the remaining three sides.

We know that the perimeter of a rectangle is given by the formula: 2L + W = 300.

From this equation, we can express W in terms of L: W = 300 - 2L.

The area of a rectangle is given by the formula: A = L * W.

Substituting the expression for W, we get: A = L * (300 - 2L).

Expanding the equation, we have:

A = 300L - 2L^2.

To find the dimensions that maximize the area, we need to find the maximum value of the area function. This can be done by taking the derivative of the area function with respect to L and setting it equal to zero.

dA/dL = 300 - 4L.

Setting the derivative equal to zero, we get: 300 - 4L = 0.

Solving for L, we find: L = 75.

Substituting this value back into the equation for W, we get: W = 300 - 2(75) = 150.

Therefore, the dimensions that make the area as large as possible are a length of 75 feet and a width of 150 feet.

The function f(x) = ((x+1)/(x-1))^3 is bijective as it is both injective and surjective, meaning it has a one-to-one correspondence between its domain and codomain.

To prove that f(x) = [tex]((x+1)/(x-1))^3[/tex]is bijective, we need to show that it is both injective and surjective.

Injectivity: To prove injectivity, we assume that f(x1) = f(x2) and show that it implies x1 = x2. So, let's assume f(x1) = f(x2) and substitute the function values:

[tex]((x1+1)/(x1-1))^3 = ((x2+1)/(x2-1))^3[/tex]

Taking the cube root of both sides, we get:

(x1+1)/(x1-1) = (x2+1)/(x2-1)

Cross-multiplying and simplifying, we have:

x1 + 1 = x2 + 1

This implies x1 = x2, which shows that the function is injective.

Surjectivity: To prove surjectivity, we need to show that for every y in the codomain, there exists an x in the domain such that f(x) = y. In this case, the codomain is R - {1}.

Let y be an arbitrary element in R - {1}. We can solve the equation f(x) = y for x:

[tex]((x+1)/(x-1))^3[/tex]= y

Taking the cube root of both sides, we get:

[tex](x+1)/(x-1) = y^(1/3)[/tex]

Cross-multiplying and simplifying, we have:

[tex]x + 1 = y^(1/3)(x - 1)[/tex]

Expanding and rearranging terms, we get:

[tex](x - y^(1/3)x) = y^(1/3) - 1[/tex]

Factoring out x, we have:

[tex]x(1 - y^(1/3)) = y^(1/3) - 1[/tex]

Dividing both sides by (1 - y^(1/3)), we get:

[tex]x = (y^(1/3) - 1)/(1 - y^(1/3))[/tex]

This shows that for any y in R - {1}, we can find an x in the domain such that f(x) = y, proving surjectivity.

Answer:

If this limit exists, then m'(x) is differentiable at x = 0. Otherwise, it is not differentiable at x = 0.

Step-by-step explanation:

To determine if m'(x) is differentiable at x = 0, we need to consider the continuity and differentiability conditions for the derivative.

Given that m' is continuous at x = 0, we know that the limit of m'(x) as x approaches 0 exists, and m'(0) is well-defined.

To determine if m'(x) is differentiable at x = 0, we need to check if the derivative of m'(x) exists at x = 0. The derivative of m'(x) is denoted as m''(x).

Given that m''(0) = 0, it suggests that the second derivative of m(x) has a critical point at x = 0. However, this information alone is not sufficient to conclude whether m'(x) is differentiable at x = 0.

To determine differentiability at x = 0, we need to analyze the behavior of m'(x) in the vicinity of x = 0. Specifically, we need to examine the limit of the difference quotient of m'(x) as x approaches 0:

lim┬(h→0)⁡〖(m'(0+h) - m'(0))/h〗

If this limit exists, then m'(x) is differentiable at x = 0. Otherwise, it is not differentiable at x = 0.

The given information does not provide any specific details about the behavior of m'(x) in the vicinity of x = 0 or any additional conditions that would allow us to determine the differentiability of m'(x) at x = 0.

Therefore, without further information, we cannot determine whether m'(x) is differentiable at x = 0 based solely on the given conditions of m''(0) = 0 and the continuity of m' at x = 0.

The function f(x) = 8 - 6x equals its average value on the interval [0,6) at the point x = 3.

To find the average value of a function on an interval, we need to calculate the definite integral of the function over that interval and divide it by the length of the interval.

The average value of f(x) on the interval [0,6) is given by:

Average value = (1/(6-0)) * ∫[0,6) f(x) dx

The integral of f(x) = 8 - 6x is obtained by using the power rule for integration:

∫[0,6) (8 - 6x) dx = [8x - 3x^2/2] evaluated from 0 to 6

Evaluating the integral, we have:

[8(6) - 3(6^2)/2] - [8(0) - 3(0^2)/2] = 48 - 54 = -6

Therefore, the average value of f(x) on the interval [0,6) is -6.

To find the point(s) at which f(x) equals its average value, we set f(x) equal to -6:

8 - 6x = -6

Simplifying the equation, we have:

6x = 14

x = 14/6 = 7/3

Therefore, the function f(x) = 8 - 6x equals its average value on the interval [0,6) at the point x = 7/3.

Using a Riemann sum with right-hand endpoints and 8 rectangles, we can approximate the vehicle's displacement, distance traveled, and average velocity over the two-hour period.

(a) To approximate the vehicle's displacement over the two hours, we can use a Riemann sum. The displacement is given by the change in position, which can be estimated by summing the areas of the rectangles formed by the function values at the right-hand endpoints. Each rectangle has a width of Δt = (2-0)/8 = 0.25 hours. The height of each rectangle is given by the function y = t³ - 1 evaluated at the right-hand endpoint. By calculating the sum of the areas of these rectangles, we can approximate the displacement over the two-hour period.

(b) To approximate the distance traveled by the vehicle over the two hours, we need to consider the absolute values of the function values. Distance is a scalar quantity and does not take into account the direction. By using the absolute values of the function values, we ensure that negative displacements are accounted for. Therefore, the process is similar to part (a), but with the absolute values of the function values.

(c) The average velocity of the vehicle over the two-hour period can be approximated by dividing the total displacement (part a) by the time interval (2 hours). This provides an estimate of the average velocity over the given time period.

Based on the calculations like multiplication, subtraction, we conclude that, Team Olympus could have tied either 28 times or 19 times.

What is subtraction?

Subtraction is one of the basic arithmetic operations in mathematics. It is a process of finding the difference or the result of taking away one quantity from another.

To determine how many times Team Olympus could have tied, we need to consider the total number of points they obtained and the points awarded for wins and ties.

In each game, Team Olympus can either win, lose, or tie. If they win a game, they receive 3 points, and if they tie a game, they receive 1 point.

Since Team Olympus played 19 games, the maximum number of points they could have earned if they won every game would be 19 * 3 = 57 points. However, they obtained a total of 28 points, which is less than the maximum possible.

To calculate the number of wins, we can subtract the number of points obtained from wins (3 points each) from the total points (28 points). The remaining points would be the number of points obtained from ties.

Number of points from ties = Total points - Number of wins * Points per win

Number of points from ties = 28 - Number of wins * 3

To find the possible number of ties, we need to determine the values of Number of wins that result in a non-negative number of points from ties.

Let's calculate the possible values:

Number of wins = 0:

Number of points from ties = 28 - 0 * 3 = 28 points

28 points can be obtained from 28 ties.

Number of wins = 1:

Number of points from ties = 28 - 1 * 3 = 25 points

25 points cannot be obtained from ties since it is not divisible by 1.

Number of wins = 2:

Number of points from ties = 28 - 2 * 3 = 22 points

22 points cannot be obtained from ties since it is not divisible by 1.

Number of wins = 3:

Number of points from ties = 28 - 3 * 3 = 19 points

19 points can be obtained from 19 ties.

Based on the calculations, Team Olympus could have tied either 28 times or 19 times.

The area of the four-leaf rose with the equation r = 2cos(20) is approximately 2.758 square units.

The four-leaf rose is a polar curve represented by the equation r = 2cos(20). To find its area, we can integrate the equation over the desired region. The limits of integration for the angle θ would typically be from 0 to 2π, covering a full revolution. However, since the curve has four petals, we need to evaluate the area for only one-fourth of the curve.

By integrating the equation r = 2cos(20) from 0 to π/10, we can calculate the area of one petal. Using the formula for polar area, A = (1/2)∫[r(θ)]^2dθ, where r(θ) is the polar equation, we can compute the area.

Performing the integration and evaluating the result, we find that the area of one petal is approximately 0.344 square units. Since the four-leaf rose has four identical petals, the total area enclosed by the curve is four times this value, giving us an approximate total area of 2.758 square units.

To approximate the integral of x² [tex]e^{(-x^2)}[/tex] dx using a series, expand  [tex]e^{(-x^2)}[/tex] as a power series and integrate each term. The number of terms needed depends on the desired accuracy.

To approximate the integral of x²  [tex]e^{(-x^2)}[/tex] dx using a series, we can express the function  [tex]e^{(-x^2)}[/tex] as a power series expansion and then integrate it term by term.

The power series expansion of  [tex]e^{(-x^2)}[/tex] is given by:

 [tex]e^{(-x^2)}[/tex] = 1 - x² + (x² * x²)/2! - (x² * x² * x²)/3! + ...

To approximate the integral, we can integrate each term of the series individually. The integral of x²  [tex]e^{(-x^2)}[/tex] dx is therefore:

∫(x²  [tex]e^{(-x^2)}[/tex]dx) = ∫(x² * (1 - x² + (x² * x²)/2! - (x² * x² * x²)/3! + ...)) dx

Integrating each term, we get:

(b) (f ◦ c)'(t) = (5t + 2) * e^(t(5t + 2) * 3t)

(c) (f ◦ c)'(t) = Simplified expression involving exponentials, logarithms, and derivatives of trigonometric functions.

(d) (f ◦ c)'(t) = exp(2t^2) + 2t * exp(2t^2)

To verify the first special case of the chain rule for the compositions, let's calculate the derivatives for each case:

(a) Given f(x, y) = xy and c(t) = (et, cos(t))

The composition is (f ◦ c)(t) = f(c(t)) = f(et, cos(t)) = (et * cos(t))

Taking the derivative, we have:

(f ◦ c)'(t) = (et * -sin(t) + cos(t) * et)

So, (f ◦ c)'(t) = et * (-sin(t) + cos(t))

(b) Given f(x, y) = exy and c(t) = (5t + 2, 3t)

The composition is (f ◦ c)(t) = f(c(t)) = f(5t + 2, 3t) = e^(t(5t + 2) * 3t)

The composition is (f ◦ c)(t) = f(c(t)) = f(et, e^-t) = (et^2 + e^-t^2) * log(et^2 + e^-t^2)

Taking the derivative, we have:

(f ◦ c)'(t) = (2et + (-e^-t)) * (et^2 + e^-t^2) * log(et^2 + e^-t^2) + (et^2 + e^-t^2) * (2et + (-e^-t)) * (1/(et^2 + e^-t^2)) * (2et + (-e^-t))

Simplifying the expression will give the final result.

The composition is (f ◦ c)(t) = f(c(t)) = f(t, -t) = t * exp(t^2 + (-t)^2) = t * exp(2t^2)

Taking the derivative, we have:

(f ◦ c)'(t) = exp(2t^2) + 2t * exp(2t^2)

The series Σ NA 1.4^n=1 does not converge; it diverges. This conclusion is drawn based on the result of the Ratio Test, which yields a limit of infinity (oo).

To test the convergence of the series Σ NA 1.4^n=1 using the Ratio Test, we consider the limit as n approaches infinity of the absolute value of the ratio of consecutive terms: lim(n→∞) |(A(n+1)1.4^(n+1)) / (A(n)1.4^n)|.

Simplifying the expression, we obtain lim(n→∞) |(10(n+1) + 10) / (10n + 10)| / 1.4. Dividing both numerator and denominator by 10, the expression becomes lim(n→∞) |(n+1 + 1) / (n + 1)| / 1.4.

As n approaches infinity, the term (n+1)/(n+1) approaches 1. Thus, the limit becomes lim(n→∞) |1 / 1| / 1.4 = 1 / 1.4 = 5/7.

Since the limit of the ratio is less than 1, we can conclude that the series Σ NA 1.4^n=1 converges if the limit were a finite number. However, the limit of 5/7 indicates that the series does not converge. Instead, it diverges, implying that the terms of the series do not approach a finite value as n tends to infinity.
