To evaluate the integral ∫(4 / (4√(1 - sin(x))) dx, we can simplify it by using a trigonometric identity. The result is 2 arcsin(sqrt((1 + sin(x)) / 2)) + C.

To evaluate the integral ∫(4 / (4√(1 - sin(x))) dx, we can simplify the expression by using a trigonometric identity. The identity states that √(1 - sin(x)) = √((1 + sin(x)) / 2).Using this identity, the integral becomes ∫(4 / (4√(1 - sin(x))) dx = ∫(4 / (4√((1 + sin(x)) / 2))) dx.Simplifying further, we can cancel out the 4 in the numerator and denominator: ∫(1 / √((1 + sin(x)) / 2)) dx.

Next, we can apply another trigonometric identity, which is √(1 + sin(x)) = 2sin(x/2).Using this identity, the integral becomes ∫(1 / √((1 + sin(x)) / 2)) dx = ∫(1 / (2sin(x/2))) dx.Now, we can evaluate this integral. The integral of (1 / (2sin(x/2))) with respect to x is 2 arcsin(sqrt((1 + sin(x)) / 2)) + C.Therefore, the result of the integral ∫(4 / (4√(1 - sin(x))) dx is 2 arcsin(sqrt((1 + sin(x)) / 2)) + C, where C represents the constant of integration.

Therefore, the top of the ladder is sliding down the wall at a rate of 3.75 ft/sec (negative rate) when the bottom is 15 feet from the wall.

To solve this problem, we can use related rates and the Pythagorean theorem.

Let's denote the distance between the bottom of the ladder and the wall as x, and the height of the ladder (distance from the ground to the top of the ladder) as y. We are given that dx/dt = -2 ft/sec (negative because the bottom is sliding away from the wall).

According to the Pythagorean theorem, x^2 + y^2 = 17^2.

Differentiating both sides of the equation with respect to time t, we get:

2x(dx/dt) + 2y(dy/dt) = 0.

Substituting the given values, x = 15 ft and dx/dt = -2 ft/sec, we can solve for dy/dt:

2(15)(-2) + 2y(dy/dt) = 0,

-60 + 2y(dy/dt) = 0,

2y(dy/dt) = 60,

dy/dt = 60 / (2y).

To find the value of y, we can use the Pythagorean theorem:

x^2 + y^2 = 17^2,

15^2 + y^2 = 289,

y^2 = 289 - 225,

y^2 = 64,

y = 8 ft.

Now we can substitute y = 8 ft into the equation to find dy/dt:

dy/dt = 60 / (2 * 8) = 60 / 16 = 3.75 ft/sec.

The critical point of the function f(x) = 4x² + 3x - 1 is x = -3/8.

To find the critical points of the function f(x) = 4x² + 3x - 1, we need to find the values of x where the derivative of f(x) is equal to zero or does not exist.

First, let's find the derivative of f(x) using the power rule:

f'(x) = d/dx (4x²) + d/dx (3x) + d/dx (-1)

= 8x + 3

To find the critical points, we set the derivative equal to zero and solve for x: 8x + 3 = 0

Subtracting 3 from both sides: 8x = -3

Dividing by 8: x = -3/8

Therefore, the critical point of the function f(x) = 4x² + 3x - 1 is x = -3/8.

a) We need to find dA/dw when w = 5 and S(5) = 35000 and S'(5) = 2000.

We know that A(w) = wS(w).

By product rule, dA/dw = wdS/dw + S.

We need to find dA/dw when w = 5.So, dA/dw = 5dS/dw + S  ...............................(1)

Given, S(5) = 35000.

So, we know the value of S at w = 5.

Given, S'(5) = 2000.

So, dS/dw at w = 5 is 2000.

Now, putting w = 5, dS/dw = 2000 and S = 35000 in equation (1), we get

dA/dw = 5dS/dw + S= 5 × 2000 + 35000= 45000

Therefore, the value of dA/dw at w = 5 when S(5) = 35000 and S'(5) = 2000 is 45000.b) In part (a), we found that dA/dw = 45000 when w = 5. Therefore, when the company has 5 workers and the average salary per worker is $35000, then increasing the number of workers by one will increase the average payroll by $45000.

So, the probability of rolling two consonants is 1/1.

The probability of rolling two consonants when rolling a six-sided cube with the letters S, O, L, V, E and D, we first need to determine the number of consonants and the total number of outcomes.

The given letters are S, O, L, V, E, and D. Out of these, the consonants are S, L, V and D.

So, there are 4 consonants in total.

The cube has 6 sides, meaning there are 6 possible outcomes when rolling it.

To find the probability, we divide the number of favorable outcomes (rolling two consonants) by the total number of outcomes.

The number of favorable outcomes is given by the number of ways we can choose 2 consonants out of the 4 available.

This can be calculated using combinations, denoted as "C."

The number of ways to choose 2 consonants out of 4 is written as C(4, 2) or 4C2.

C(4, 2) = 4! / (2! × (4 - 2)!)

= 4! / (2! × 2!)

= (4 × 3 × 2 × 1) / (2 × 1 × 2 × 1)

= 6

So, there are 6 ways to choose 2 consonants out of the 4 available.

The total number of outcomes is 6, as there are 6 sides on the cube.

Now, we can calculate the probability:

Probability of rolling two consonants = Number of favorable outcomes / Total number of outcomes

Probability of rolling two consonants = 6 / 6 = 1

The probability of rolling two consonants is 1.

Expressing it as a fraction in simplest form, we have:

The series Σ[tex](1/n^2)[/tex] has p = 2, which is greater than 1. Therefore, the series converges.

The individual lifetime of each object is exponentially distributed, and exponential decay is a scalar multiple of this distribution, which has a well-known predicted value.

1. To prove that lim(n->∞) [tex](1 + 2)^n[/tex] = 0, we can use the concept of exponential decay and the fact that the series 1 + 2 + [tex]2^2[/tex] + ... is a geometric series.

We know that a geometric series with a common ratio between -1 and 1 converges. In this case, the common ratio is 2, which is greater than 1. Therefore, the series diverges.

However, the limit of the terms of the series, [tex](1 + 2)^n[/tex], as n approaches infinity is 0. This can be proven using the concept of exponential decay. As n becomes larger and larger, the term [tex](1 + 2)^n[/tex] becomes infinitesimally small, approaching 0. Therefore, lim(n->∞) [tex](1 + 2)^n[/tex] = 0.

The theorem used in this proof is the concept of exponential decay and the knowledge of the behavior of geometric series.

2. To determine if the series Σ[tex](1/n^2)[/tex] from n=1 to ∞ converges absolutely, conditionally, or diverges, we can use the p-series test.

The p-series test states that for a series of the form Σ[tex](1/n^p)[/tex], if p > 1, the series converges, and if p ≤ 1, the series diverges.

In this case, the series Σ[tex](1/n^2)[/tex] has p = 2, which is greater than 1. Therefore, the series converges.

Since the series converges, it also converges absolutely because the terms of the series are all positive. Absolute convergence means that the rearrangement of terms will not change the sum of the series.

The statistics for the finishing times change. The mean difference in finishing time is now -13.40, with a standard deviation of 20.57. In order to make further conclusions, we need to assess the assumptions and conditions, construct a confidence interval, and perform a hypothesis test.

a) Assumptions and conditions:

In order to make valid inferences about the mean difference in finishing time, several assumptions and conditions should be met. These include independence of observations, normality of the population distribution (or large sample size), and no outliers or influential observations. Additionally, the differences in finishing time should be approximately normally distributed.

b) Confidence interval:

To construct a 95% confidence interval for the mean difference in finishing time, we would use the formula:

mean difference ± (critical value) * (standard deviation / sqrt(sample size))

The critical value is determined based on the desired confidence level and the sample size.

c) Hypothesis test:

To test the null hypothesis of no difference in finishing time, we would perform a hypothesis test using the appropriate test statistic (such as the t-test) and a significance level of α=0.05. The test would assess whether the observed mean difference is statistically significant.

Based on the provided information, the conclusion would depend on the results of the hypothesis test. If the test yields a p-value less than 0.05, we would reject the null hypothesis and conclude that there is evidence of a difference in finishing time.

To find the second-order derivatives, we will differentiate the function r(x,y) twice with respect to x and y.

First, let's find rxx(x,y), which represents the second-order derivative with respect to x. Taking the partial derivative of r(x,y) with respect to x, we get:

r_x(x,y) = y/(8x + 9y)

Differentiating r_x(x,y) with respect to x, we obtain:

Now, let's find rxy(x,y), which represents the mixed second-order derivative with respect to x and y. Taking the partial derivative of r_x(x,y) with respect to y, we get:

rxy(x,y) = -8/[tex](8x + 9y)^2[/tex]

Finally, let's find ryx(x,y), which represents the mixed second-order derivative with respect to y and x. Taking the partial derivative of r_y(x,y) with respect to x, we get:

ryx(x,y) = -8/[tex](8x + 9y)^2[/tex]

So, the second-order derivatives for r(x,y) are:

rxx(x,y) = -8y/[tex](8x + 9y)^2[/tex]

ryy(x,y) = -9x/[tex](8x + 9y)^2[/tex]

The curl of the vector field F = <6ycos(x), 2xsin(y)> is given by (2sin(y)) * i + (6cos(x)) * j.

The curl of a vector field is a vector operation that measures the rotation or circulation of the vector field. In this case, we want to find the curl of the vector field F.

The curl of a vector field F = <P, Q> is given by the following formula:

curl(F) = (∂Q/∂x - ∂P/∂y) * i + (∂P/∂x + ∂Q/∂y) * j

Now, let's compute the partial derivatives of the vector field components and substitute them into the curl formula.

∂P/∂y = ∂/∂y (6ycos(x)) = 6cos(x)

∂Q/∂x = ∂/∂x (2xsin(y)) = 2sin(y)

Substituting these partial derivatives into the curl formula, we get:

curl(F) = (2sin(y)) * i + (6cos(x)) * j

So, the curl of the vector field F = <6ycos(x), 2xsin(y)> is given by (2sin(y)) * i + (6cos(x)) * j.

In simpler terms, the curl represents the tendency of the vector field to circulate or rotate around a point.

In this case, the curl of F tells us that the vector field rotates in the x and y directions with a magnitude determined by the sine and cosine functions.

If sin(θ) > 0, then θ could lie in Quadrant I or Quadrant II, as the sine function is positive in these quadrants. Your answer: Quadrant I.

If sin(0) > 0, it means that the sine of 0 degrees is greater than 0. However, in reality, sin(0) = 0, not greater than 0. The sine function gives the vertical coordinate of a point on the unit circle corresponding to a given angle. At 0 degrees, the point lies on the positive x-axis, and its y-coordinate (sine value) is 0.

Since sin(0) = 0, it does not satisfy the condition sin(0) > 0. Therefore, 0 does not lie in any quadrants because 0 degrees falls on the positive x-axis and does not fall within any of the quadrants (Quadrant I, Quadrant II, Quadrant III, or Quadrant IV).

The equation of an ellipse can be represented in the standard form as (x/30)^2 + (y/a)^2 = 1, where 'a' is the distance from the center of the ellipse to one of the vertices. In this case, the given ellipse is centered at the origin, so the center coordinates are (0, 0). The distance from the center to one of the vertices is 30, so 'a' is equal to 30.

The eccentricity of an ellipse, denoted by 'e,' determines the shape of the ellipse. It is calculated as the ratio of the distance between the center and one of the foci to the distance between the center and one of the vertices. Given that the eccentricity is 0.29, we can use the formula e = c/a, where 'c' is the distance between the center and one of the foci. Rearranging the formula, we find c = e * a = 0.29 * 30 = 8.7.

The limit of tanh(x) as x approaches infinity or negative infinity is 1 and -1, respectively. The derivative of f(x) = tanh(Vx+) + 4 is f'(x) = Vsech²(Vx+) where sech(x) is the hyperbolic secant function.

To find the absolute maximum and minimum values of f(x) on a given interval, we need to analyze the critical points and endpoints of the interval.

The hyperbolic tangent function, tanh(x), is defined as (e^x - e^(-x))/(e^x + e^(-x)). As x approaches positive infinity, both the numerator and denominator of the fraction approach infinity, resulting in a limit of 1.

Similarly, as x approaches negative infinity, the numerator and denominator approach negative infinity, giving a limit of -1.

Therefore, the limit of tanh(x) as x approaches infinity or negative infinity is 1 and -1, respectively.

To find the derivative of f(x) = tanh(Vx+) + 4, we can use the chain rule. The derivative of tanh(x) is sech²(x), where sech(x) is the hyperbolic secant function defined as 1/cosh(x).

Applying the chain rule, we get f'(x) = Vsech²(Vx+).

This derivative represents the rate of change of the function f(x) with respect to x.

To determine the absolute maximum and minimum values of f(x) on a given interval, we need to consider the critical points and endpoints of the interval. The critical points occur where the derivative is either zero or undefined. In this case, since the derivative f'(x) = Vsech²(Vx+), the critical points occur where sech²(Vx+) = 0. However, sech²(x) is always positive, so there are no critical points.

Next, we examine the endpoints of the given interval. If the interval is bounded, we evaluate f(x) at the endpoints and compare the values to determine the absolute maximum and minimum. If the interval is unbounded, as x approaches positive or negative infinity, f(x) approaches 4. Therefore, the absolute maximum and minimum values of f(x) on the given interval are both 4.

To evaluate the line integral ∮C F · dr, where C is the ellipse parameterized by x = a cos(t), y = b sin(t) with 0 ≤ t ≤ 2π, and F(x, y) = <0, 2>, we will:

1: Parameterize the curve C with respect to t.

Since x = a cos(t) and y = b sin(t), the curve C can be expressed as r(t) = <a cos(t), b sin(t)>, where t ranges from 0 to 2π.

2: Calculate dr.

Differentiating the parameterization with respect to t, we get dr = <-a sin(t), b cos(t)> dt.

3: Evaluate F(r(t)) · dr.

Substituting the parameterized values of x and y into F(x, y) = <0, 2>, we have F(r(t)) = <0, 2>. So, F(r(t)) · dr = <0, 2> · <-a sin(t), b cos(t)> dt = 2b cos(t) dt.

4: Integrate over the range of t.

The line integral becomes:

∮C F · dr = ∫[0, 2π] 2b cos(t) dt.

Integrating 2b cos(t) with respect to t gives:

∫[0, 2π] 2b cos(t) dt = 2b ∫[0, 2π] cos(t) dt.

The integral of cos(t) over one period is zero, so the line integral evaluates to:

∮C F · dr = 2b * 0 = 0.

To evaluate the limit lim z→0 (e² + 2x - 1)/(6x) using L'Hôpital's rule, we differentiate the numerator and the denominator separately with respect to x and then take the limit again.

Applying L'Hôpital's rule, we differentiate the numerator and the denominator with respect to x. The derivative of e² + 2x - 1 with respect to x is simply 2, since the derivative of e² is 0 (as it is a constant) and the derivative of 2x is 2. Similarly, the derivative of 6x with respect to x is 6. Thus, we have the new limit lim z→0 (2)/(6).

Now, as z approaches 0, the limit evaluates to 2/6, which simplifies to 1/3. Therefore, the limit of (e² + 2x - 1)/(6x) as z approaches 0 is 1/3.

By using L'Hôpital's rule, we were able to simplify the expression and evaluate the limit by differentiating the numerator and denominator. This technique is particularly useful when dealing with indeterminate forms like 0/0 or ∞/∞, allowing us to find the limit of a function that would otherwise be difficult to determine.

y = (x/2) In x + Ax^(2 - x) + B is the the general solution of the differential equation y In x - x - 2y' = 0.

The differential equation yy' = -8 cos (ntx) has the general solution given by y = A sin(ntx) - 4 cos(ntx) + B, where A and B are constants.

Let's derive the solution by integrating the given differential equation. The differential equation yy' = -8 cos (ntx) can be written as yy' + 4 cos (ntx) = 0. Dividing by y and integrating with respect to x on both sides, we have:

[tex]∫(1/y) dy = - ∫(4 cos (ntx) dx)log|y| = - (4/n) sin (ntx) + C1[/tex]

where C1 is the constant of integration. Taking exponentials on both sides of the above equation, we get |y| = e^(C1) e^(-4/n sin(ntx)).

Now, let A = e^(C1) and B = -e^(C1). Hence, the general solution of the differential equation yy' = -8 cos (ntx) is given by y = A sin(ntx) - 4 cos(ntx) + B.

For the differential equation V1 - 4x² y' = x, let's solve it using the method of separation of variables. The given differential equation can be written as y' = (V1 - x)/(4x²). Multiplying both sides by dx/(V1 - x), we get (dy/dx) (dx/(V1 - x)) = dx/(4x²).

Integrating both sides, we get ln|V1 - x| = -1/(4x) + C2, where C2 is the constant of integration. Taking exponentials on both sides of the above equation, we get |V1 - x| = e^(-1/(4x) + C2).

Let A = e^(C2) and B = -e^(C2). Hence, the general solution of the differential equation V1 - 4x² y' = x is given by y = (1/4) ln|V1 - x| + A x + B.

For the differential equation y In x - x - 2y' = 0, let's solve it using the method of separation of variables. The given differential equation can be written as (y In x - 2y')/x = 1. Multiplying both sides by x, we get y In x - 2y' = x.

Integrating both sides with respect to x, we get xy In x - x² + C3 = 0, where C3 is the constant of integration. Taking exponentials on both sides of the above equation, we get x^x e^(C3) = x².

Dividing by x² on both sides, we get x^(x-2) = e^(C3). Let A = e^(C3) and B = -e^(C3). Hence, the general solution of the differential equation y In x - x - 2y' = 0 is given by y = (x/2) In x + Ax^(2 - x) + B.

To determine the time it takes for an investment to triple with continuous compounding, we can use the formula for continuous compound interest:A = P * e^(rt) . It will take approximately 36.6 years for the investment to triple .

Where: A = Final amount (triple the initial investment) P = Principal amount (initial investment) e = Euler's number (approximately 2.71828) r = Interest rate (in decimal form) t = Time (in years)

We want to solve for t, so we can rearrange the formula as follows:
3P = P * e^(0.03t)

Dividing both sides by P, we get:
3 = e^(0.03t)

To isolate t, we can take the natural logarithm (ln) of both sides:
ln(3) = ln(e^(0.03t))

Using the property of logarithms (ln(a^b) = b * ln(a)):
ln(3) = 0.03t * ln(e)

Since ln(e) equals 1, the equation simplifies to:
ln(3) = 0.03t

Now, we can solve for t by dividing both sides by 0.03:
t = ln(3) / 0.03 ≈ 36.6 years

Rounding to the nearest tenth of a year, it will take approximately 36.6 years for the investment to triple with continuous compounding at a 3% interest rate.

The derivative y' is  x³ 6² cosh¹2x . 3x² 6² sinh(2x) / (x³ cosh(2x))= 3x 6² sinh(2x) / cosh(2x)

(i) Find the derivative y',

y = (x² + 1) arctan x - x

The given function is:y = (x² + 1) arctan x - x

To find the derivative of y with respect to x, use the following steps:

Find the derivative of the first term, (x² + 1) arctan x by applying the product rule. Then, find the derivative of the second term, -x, by applying the power rule.

Add the results to find y'.y = (x² + 1) arctan x - x

Let's find the derivative of the first term, (x² + 1) arctan x:Let u = (x² + 1) and v = arctan x

Differentiate u to get du/dx:du/dx = 2x

Differentiate v to get dv/dx:dv/dx = 1 / (1 + x²)

Using the product rule, find the derivative of the first term:d/dx (u.v) = u . dv/dx + v . du/dx= (x² + 1) . 1 / (1 + x²) + 2x . arctan x

Now, let's find the derivative of the second term: d/dx (-x) = -1

Therefore, the derivative of y with respect to x is:y' = (x² + 1) . 1 / (1 + x²) + 2x . arctan x - 1(ii)

(ii) Find the derivative y', given: y = sinh(2rlogr)

The given function is:y = sinh(2rlogr)

To find the derivative of y with respect to r, use the chain rule. Let's apply the chain rule, where y' represents the derivative of y with respect to r:y = sinh(2rlogr) = sinh(u)where u = 2rlogr

Then, find the derivative of u with respect to r:du/dx = 2logr + 2r / rdu/dx = 2logr + 2r

Then, find the derivative of y with respect to u:dy/du = cosh(u)

Now, using the chain rule, we can find y' as follows:y' = dy/dx = dy/du . du/dx= cosh(u) . (2logr + 2r)

Therefore, the derivative of y with respect to r is:y' = 2r cosh(2rlogr) + 2 log r . sinh(2rlogr)(b)

b) Find y' if y = x³ 6² cosh¹2x using logarithmic differentiation

The given function is:y = x³ 6² cosh¹2xWe can take the natural logarithm of both sides to make it easier to differentiate:ln y = ln(x³ 6² cosh¹2x)

Let's find the derivative of both sides with respect to x:dy/dx . 1 / y = d/dx ln(x³ 6² cosh¹2x)

Apply the power rule to find the derivative of the natural logarithm:d/dx ln(x³ 6² cosh¹2x) = 1 / (x³ 6² cosh¹2x) . d/dx (x³ 6² cosh¹2x) = 1 / (x³ 6² cosh¹2x) . (3x² 6² sinh(2x) / cosh(2x))= 3x² 6² sinh(2x) / (x³ cosh(2x))

Therefore, the derivative of y with respect to x is given by:dy/dx = y . 3x² 6² sinh(2x) / (x³ cosh(2x))

Substitute y = x³ 6² cosh¹2x:y'

y'= x³ 6² cosh¹2x . 3x² 6² sinh(2x) / (x³ cosh(2x))= 3x 6² sinh(2x) / cosh(2x)

On substituting the values of a, f(a), and f'(a), we can compute L(32.05).

To estimate the number 32.05 using linear approximation, we will construct a function f(x) such that f(32.05) represents the desired computation.

Constructing the function f(x):

Let's choose a reference value "a" close to 32.05. For simplicity, we can take a = 32.

f(x) = f(a) + f'(a)(x - a)

Providing the reference value "a":

a = 32

Obtaining the linearization of f(x):

To get the linearization of f(x), we need to calculate f(a) and f'(a).

f(a) represents the function value at the reference point "a". In this case, it is f(32).

f'(a) represents the derivative of the function at the reference point "a".

Since we don't have a specific function or context, let's assume a simple linear function:

f(x) = mx + b

f(32) = m * 32 + b

To estimate the values of m and b, we need additional information or constraints about the function.

Computing L(32.05):

L(x) = f(a) + f'(a)(x - a)

Substituting the values of a, f(a), and f'(a), we can compute L(32.05).

As x approaches positive or negative infinity, f(x) will also tend to positive or negative infinity. There are no vertical asymptotes for this function.

To sketch the function f(x) = x^3 - 6x^2 + 9x, we need to perform a full analysis, which includes finding the critical points, determining intervals of increase and decrease, locating points of inflection, and identifying any vertical asymptotes.

1. Critical Points:

To find the critical points, we need to find the values of x where the derivative of f(x) is equal to zero or undefined.

f(x) = x^3 - 6x^2 + 9x

Taking the derivative of f(x):

f'(x) = 3x^2 - 12x + 9

Setting f'(x) equal to zero:

3x^2 - 12x + 9 = 0

Factoring the equation:

3(x - 1)(x - 3) = 0

Solving for x:

x - 1 = 0 --> x = 1

x - 3 = 0 --> x = 3

The critical points are x = 1 and x = 3.

2. Intervals of Increase and Decrease:

To determine the intervals of increase and decrease, we can analyze the sign of the derivative.

Testing a value in each interval:

Interval (-∞, 1): Choose x = 0

f'(0) = 3(0)^2 - 12(0) + 9 = 9

Since f'(0) > 0, the function is increasing in this interval.

Interval (1, 3): Choose x = 2

f'(2) = 3(2)^2 - 12(2) + 9 = -3

Since f'(2) < 0, the function is decreasing in this interval.

Interval (3, ∞): Choose x = 4

f'(4) = 3(4)^2 - 12(4) + 9 = 9

Since f'(4) > 0, the function is increasing in this interval.

3. Points of Inflection:

To find the points of inflection, we need to analyze the concavity of the function. This is determined by the second derivative.

Taking the second derivative of f(x):

f''(x) = 6x - 12

Setting f''(x) equal to zero:

6x - 12 = 0

x = 2

The point x = 2 is a potential point of inflection.

Testing the concavity at x = 2:

Choose x = 2

f''(2) = 6(2) - 12 = 0

Since f''(2) = 0, we need to further test the concavity on both sides of x = 2.

Testing x = 1:

f''(1) = 6(1) - 12 = -6

Since f''(1) < 0, the concavity changes from concave up to concave down at x = 2.

Therefore, x = 2 is a point of inflection.

4. Vertical Asymptotes:

To determine if there are any vertical asymptotes, we need to check the behavior of the function as x approaches positive or negative infinity.

Now, let's summarize the analysis:

- Critical points: x = 1, x = 3

- Intervals of increase: (-∞, 1), (3, ∞)

- Intervals of decrease: (1, 3)

- Points of inflection: x = 2

the derivative of the function [tex]f(x) = e^{(2x)} + tan(x) + 12x + x^6[/tex] is [tex]f'(x) = (e^(2x) * 2) + sec^2(x) + 12 + 6x^5.[/tex]

What is derivative?

In calculus, the derivative of a function measures how the function changes as its input (independent variable) changes.

To find the derivative of the function [tex]f(x) = e^{(2x)} + tan(x) + 12x + x^6[/tex], we can use the rules of differentiation. Let's differentiate each term step by step.

The derivative of [tex]e^{(2x)}[/tex] with respect to x can be found using the chain rule. The chain rule states that if we have [tex]e^{(u(x))[/tex], the derivative is given by [tex]e^{(u(x))} * u'(x)[/tex]. In this case, u(x) = 2x, so u'(x) = 2. Therefore, the derivative of [tex]e^{(2x)[/tex] is [tex]e^{(2x)} * 2[/tex].

The derivative of tan(x) with respect to x can be found using the derivative of the tangent function, which is [tex]sec^2(x)[/tex].

The derivative of 12x with respect to x is simply 12.

The derivative of [tex]x^6[/tex] with respect to x can be found using the power rule. The power rule states that if we have [tex]x^n[/tex], the derivative is given by [tex]n * x^{(n-1)[/tex]. In this case, n = 6, so the derivative of [tex]x^6[/tex] is [tex]6 * x^{(6-1)} = 6x^5[/tex].

Putting it all together, the derivative f'(x) is:

[tex]f'(x) = (e^{(2x)} * 2) + sec^2(x) + 12 + 6x^5.[/tex]

Therefore, the derivative of the function f(x) = e^(2x) + tan(x) + 12x + x^6 is [tex]f'(x) = (e^{(2x)} * 2) + sec^2(x) + 12 + 6x^5.[/tex]
