This is the derivative of the given function h(t). The derivative shows us how much the function changes with respect to the input variable t. In other words, it tells us the rate of change of the function at any point on its domain.
To find the derivative of h(t), we can use the chain rule and the power rule of differentiation. First, we need to rewrite the function in a more readable format:
h(t) = (t^2 - 1)^(3/2) * (3t^2 - 1)^3
Next, we can apply the chain rule by taking the derivative of the outer function and multiply it by the derivative of the inner function. For the outer function, we can use the power rule of differentiation:
h'(t) = 3/2 * (t^2 - 1)^(1/2) * 2t * (3t^2 - 1)^3 + (t^2 - 1)^(3/2) * 3 * (3t^2 - 1)^2 * 6t
Simplifying this expression gives us the final answer:
h'(t) = 3t(3t^2 - 1)^2*(t^2 - 1)^(1/2) + 54t^2(t^2 - 1)^(3/2)*(3t^2 - 1)
This is the derivative of the given function h(t). The derivative shows us how much the function changes with respect to the input variable t. In other words, it tells us the rate of change of the function at any point on its domain.

Given that the radius of a circle is increasing at a rate of 10 centimeters per minute.
We need to find the rate of change of the area when the radius is 4 centimeters.
According to the question, The radius of a circle is r = 4 cm The rate of change of the radius of the circle is:
dr/dt = 10 cm/min
The area of the circle is given by:
A = πr²
Differentiating both sides with respect to time t, we have:
dA/dt = 2πr(dr/dt)
Now, put the values of dr/dt and r in the above equation, dA/dt = 2π × 4 × 10= 80π cm²/min
Therefore, the rate of change of the area when the radius is 4 cm is 80π cm²/min. Rounded to one decimal place is 251.3 cm²/min (approximately).

The Riemann Sum for the function using right endpoints is 76.08 square units, and the Riemann Sum for the function using left endpoints is 34.72 square units.
Here, we need to Estimate the area under the graph of f(x) = x² + x + 1 over the interval [1, 5] using five approximating rectangles and right endpoints.
The area of each rectangle can be calculated by the formula,Δx × f(x)We have to break the interval [1, 5] into five intervals,Δx = (b - a) / nΔx = (5 - 1) / 5Δx = 4 / 5

Halliday physics Calculate moment inertia of a rod of length L and mass M, which is located on the x- axis according to the figure respect to th y-axis,in term of M and L. unit mass of rod length is obtained from reltaion: x= x= (1 - =) L
The moment of inertia of the rod with respect to the y-axis is ML^2/4.To calculate the moment of inertia of a rod with length L and mass M with respect to the y-axis:
We need to consider the rod as a continuous object and integrate over its length. The moment of inertia, denoted as I, is given by the formula: I = ∫(r^2 dm), where r is the distance from the element of mass dm to the axis of rotation. In this case, we are considering the y-axis as the axis of rotation. Let's assume that the rod is aligned along the x-axis, with its center at the origin (0, 0). The mass element dm can be expressed in terms of the linear mass density λ as: dm = λ dx, where dx is an element of length along the rod.
From the given relation, x = (1 - x/L) L, we can solve for x in terms of L: x = (1 - x/L) L, x = L - x, 2x = L, x = L/2. Now, we can express dm in terms of dx:
dm = λ dx, dm = M/L dx. The distance r from the element of mass dm to the y-axis is simply x, which is L/2. Substituting these expressions into the formula for moment of inertia, we have: I = ∫(r^2 dm) = ∫((L/2)^2)(M/L dx)= M(L/4)(L - 0)= ML^2/4. Therefore, the moment of inertia of the rod with respect to the y-axis is ML^2/4.

(c) The integral from 5 to 5 of f(x) dx is 0.
(d) The integral from 0 to 5 of 2 dx is 10.
(a) To evaluate the integral from 0 to 7 of f(x) dx, we can add the values of the function f(x) over the interval [0, 5] and [5, 7]. Since the integral from 0 to 5 of f(x) dx is equal to 10 and the integral from 5 to 7 of f(x) dx is equal to 2, we can sum them up:
∫[0 to 7] f(x) dx = ∫[0 to 5] f(x) dx + ∫[5 to 7] f(x) dx
= 10 + 2
= 12
Therefore, the value of the integral from 0 to 7 of f(x) dx is 12.
(b) To evaluate the integral from 5 to 0 of f(x) dx, we need to reverse the limits and change the sign:
∫[5 to 0] f(x) dx = -∫[0 to 5] f(x) dx
= -(10)
= -10
Therefore, the value of the integral from 5 to 0 of f(x) dx is -10.
(c) The integral from 5 to 5 of f(x) dx represents the integral over a zero interval. Since the function does not change over this interval, the value of the integral is 0.
∫[5 to 5] f(x) dx = 0
Therefore, the value of the integral from 5 to 5 of f(x) dx is 0.
(d) The integral from 0 to 5 of 2 dx represents the integral of the constant function 2 over the interval [0, 5]. Since the function is constant, we can simply multiply the constant value by the length of the interval:
∫[0 to 5] 2 dx = 2 × (5 - 0)
= 2 × 5
= 10
Therefore, the value of the integral from 0 to 5 of 2 dx is 10.

Define the force field F(x,y,z)=⟨xy,−yz,xz⟩. 1. Find the divergence and curl of F. 2. Let C be the directed line segment from (0,0,0) to (1,1,2). Find the work done by F in moving a particle along C. 3. Let S be the portion of the plane z=2−2x in the first octant bounded by the coordinate planes and the plane y=1 with upward orientation. Set up an iterated double integral equal to the flux of F across S.
1. the divergence of F is x + y - z, and the curl of F is y i - x k.
2. the work done by F in moving a particle along C is 1/6.
1. To find the divergence and curl of the vector field F(x, y, z) = ⟨xy, -yz, xz⟩, we can use the following formulas:
Divergence (div(F)):
The divergence of a vector field F = ⟨P, Q, R⟩ is given by:
div(F) = ∇ · F = (∂P/∂x) + (∂Q/∂y) + (∂R/∂z)
Curl (curl(F)):
The curl of a vector field F = ⟨P, Q, R⟩ is given by:
curl(F) = ∇ × F = (∂R/∂y - ∂Q/∂z) i + (∂P/∂z - ∂R/∂x) j + (∂Q/∂x - ∂P/∂y) k
Let's calculate the divergence and curl of F:
∂P/∂x = y, ∂Q/∂y = -z, ∂R/∂z = x
∂R/∂y = 0, ∂Q/∂z = -y, ∂P/∂z = 0
∂Q/∂x = 0, ∂P/∂y = x, ∂R/∂x = z
Divergence (div(F)):
div(F) = (∂P/∂x) + (∂Q/∂y) + (∂R/∂z)
= y + (-z) + x
= x + y - z
Curl (curl(F)):
curl(F) = (∂R/∂y - ∂Q/∂z) i + (∂P/∂z - ∂R/∂x) j + (∂Q/∂x - ∂P/∂y) k
= 0 - (-y) i + 0 j + 0 - x k
= y i - x k
Therefore, the divergence of F is x + y - z, and the curl of F is y i - x k.
2. To find the work done by F in moving a particle along the directed line segment C from (0, 0, 0) to (1, 1, 2), we use the line integral:
Work = ∫C F · dr
where F is the vector field and dr is the differential displacement vector along the path C.
Parameterize the line segment C as a vector function r(t) = ⟨x(t), y(t), z(t)⟩:
x(t) = t, y(t) = t, z(t) = 2t
The differential displacement vector dr = ⟨dx, dy, dz⟩ = ⟨dx/dt, dy/dt, dz/dt⟩ dt:
dr = ⟨dx/dt, dy/dt, dz/dt⟩ dt = ⟨1, 1, 2⟩ dt
Substitute the parameterization and the vector field F into the line integral:
Work = ∫C F · dr
= ∫₀¹ (F · dr)
= ∫₀¹ ⟨xy, -yz, xz⟩ · ⟨1, 1, 2⟩ dt
= ∫₀¹ (xy + (-yz) + 2xz) dt
= ∫₀¹ (t * t + (-(t * 2)) + 2t * t) dt
= ∫₀¹ (t² - 2t² + 2t³) dt
= ∫₀¹ (-t² + 2t³) dt
Integrate with respect to t:
Work = [-t³/3 + (2/4)t⁴]₀¹
= [-(1/3) + (2/4)] - [0]
= -(1/3) + 1/2
= -1/3 + 3/6
= -1/3 + 1/2
= 1/6
Therefore, the work done by F in moving a particle along C is 1/6.
3. To set up an iterated double integral equal to the flux of F across the surface S, we can use the following formula:
Flux = ∬S F · dS
where F is the vector field and dS is the outward-pointing differential surface area vector.
The given surface S is the portion of the plane z = 2 - 2x in the first octant, bounded by the coordinate planes and the plane y = 1.
To set up the iterated double integral, we need to express the surface S in terms of two variables, typically x and y.
The surface S is bounded by the coordinate planes, so its boundaries in the x-y plane are x = 0, y = 0, and y = 1.
The equation of the plane z = 2 - 2x can be rewritten as x = (2 - z)/2.
Therefore, the bounds for x are 0 ≤ x ≤ (2 - z)/2, and the bounds for y are 0 ≤ y ≤ 1.
The differential surface area vector dS can be calculated as:
dS = ⟨-∂z/∂x, -∂z/∂y, 1⟩ dA
where dA is the differential area element in the x-y plane.
∂z/∂x = -2/2 = -1
∂z/∂y = 0
Therefore, dS = ⟨-1, 0, 1⟩ dA.
The flux of F across S is:
Flux = ∬S F · dS
= ∬S ⟨xy, -yz, xz⟩ · ⟨-1, 0, 1⟩ dA
= ∬S (-xy + xz) dA
Set up the iterated double integral:
Flux = ∫₀¹ ∫₀((2 - z)/2) (-xy + xz) dx dy
Evaluate this double integral using the given bounds to find the flux of F across S.

Answer: Choice B.
No, because one x-value corresponds to two different y-values.
Specifically we have x = 3 map to both y = 5 and y = 6 at the same time. A function is only possible when each x value goes to one y value only.
A handy trick is to look at the list of x coordinates. If any x coordinates repeat themselves, then we likely won't have a function.
The y values can repeat, but the function won't be one-to-one.

Neither systematic error nor random error is compensable, O b. Systematic error is compensable, while random error is not O c. Both systematic error and random error are compensable O d. Systematic error is not compensable, while random error is compensabl
The correct statement is systematic error is not compensable, while random error is compensable. Option d is correct.
Systematic error refers to a consistent and predictable deviation from the true value in the same direction, usually caused by flaws in the measurement process. Systematic errors are not compensable because they cannot be reduced or eliminated by repeating the measurements. They affect all measurements in a consistent manner.
On the other hand, random error refers to the unpredictable fluctuations or variations in measurement readings around the true value. Random errors are caused by factors such as environmental noise, instrument limitations, or human error.
Random errors can be reduced or minimized by taking multiple measurements and applying statistical techniques. By averaging multiple measurements, the random errors tend to cancel out, allowing for a more accurate estimation of the true value.
Therefore, d is correct.

The expression can be simplified as follows:
a. \( f(g(0)) = f((-3)) = (-3) + 4 = 1 \)
b. \( g(f(0)) = g(4) = 4^{2} - 3 = 13 \)
c. \( f(g(x)) = f(x^{2} - 3) = (x^{2} - 3) + 4 = x^{2} + 1 \)
d. \( g(f(x)) = g(x + 4) = (x + 4)^{2} - 3 = x^{2} + 8x + 13 \)
e. \( f(f(-4)) = f((-4) + 4) = 0 \)
f. \( g(g(2)) = g(2^{2} - 3) = g(1) = 1^{2} - 3 = -2 \)
g. \( f(f(x)) = f(x + 4) = (x + 4) + 4 = x + 8 \)
h. \( g(g(x)) = g(x^{2} - 3) = (x^{2} - 3)^{2} - 3 \)
a. To find \( f(g(0)) \), we substitute 0 into the function \( g(x) \) first. This gives us \( g(0) = 0^{2} - 3 = -3 \). Then we substitute the result into the function \( f(x) \), which gives us \( f(-3) = (-3) + 4 = 1 \).
b. To find \( g(f(0)) \), we substitute 0 into the function \( f(x) \) first. This gives us \( f(0) = 0 + 4 = 4 \). Then we substitute the result into the function \( g(x) \), which gives us \( g(4) = 4^{2} - 3 = 13 \).

The limit is: [tex]lim_(x→(-9π/2)) (-tan(x) - tan(2-9π)/(x+9π/2)) = 1[/tex]. Ans: `1`
We are given the limit as
[tex]lim_(x→(-9π/2)) (-tan(x) - tan(2-9π)/(x+9π/2))[/tex]
Putting the value of x = (-9π/2), we get:
[tex]lim_(x→(-9π/2)) (-tan(x) - tan(2-9π)/(x+9π/2))=lim_(x→(-9π/2)) (-tan(x) - tan(π/2+9π/2))/(x+9π/2))[/tex]
We know that
[tex]tan(π/2 + θ) = -cot(θ)lim_(x→(-9π/2)) (-tan(x) + cot(9π/2 - 2))/(x+9π/2))[/tex]
[tex]=-lim_(x→(-9π/2)) (tan(x) - cot(2 - 9π/2))/(x+9π/2))\\=-lim_(x→(-9π/2)) [(sin(x)/cos(x) - cos(2 - 9π/2)/sin(2 - 9π/2)) /(x+9π/2))] × [(cos(x) sin(2-9π/2))/(cos(x) sin(2-9π/2))][/tex]
Now,[tex]lim_(x→(-9π/2)) cos(x) sin(2-9π/2) = cos(-9π/2) sin(2-9π/2) = (-1)(-1) = 1[/tex]
Also,
[tex]sin(x)/cos(x) = tan(x) and cos(2-9π/2)/sin(2-9π/2) \\= -cot(9π/2 - 2) \\= -tan(2-9π/2)[/tex]
Therefore,[tex]lim_(x→(-9π/2)) [(sin(x)/cos(x) - cos(2 - 9π/2)/sin(2 - 9π/2)) /(x+9π/2))] × [(cos(x) sin(2-9π/2))/(cos(x) sin(2-9π/2))][/tex]
[tex]=lim_(x→(-9π/2)) [(tan(x) - tan(2 - 9π/2))/(x+9π/2))] × [(cos(x) sin(2-9π/2))/(cos(x) sin(2-9π/2))] \\=1 × lim_(x→(-9π/2)) [(tan(x) - tan(2 - 9π/2))/(x+9π/2))][/tex]
Now, [tex]lim_(x→(-9π/2)) (tan(x) - tan(2 - 9π/2))/(x+9π/2))[/tex]is in the form of 0/0
Hence, we can use L'Hospital's Rule.
[tex]Let f(x) = tan(x) - tan(2 - 9π/2) and g(x) = x + 9π/2lim_(x→(-9π/2)) [(tan(x) - tan(2 - 9π/2))/(x+9π/2))] \\= lim_(x→(-9π/2)) [(f(x))/(g(x))]lim_(x→(-9π/2)) f'(x) \\= sec²(x)lim_(x→(-9π/2)) g'(x) \\= 1[/tex]
Using L'Hospital's Rule, we get
[tex]lim_(x→(-9π/2)) [(tan(x) - tan(2 - 9π/2))/(x+9π/2))] = lim_(x→(-9π/2)) [sec²(x)/(1)] \\= sec²(-9π/2) \\= sec²(π/2) \\= 1[/tex]
Therefore, [tex]lim_(x→(-9π/2)) (-tan(x) - tan(2-9π)/(x+9π/2)) = 1[/tex]Ans: `1`

The equation r(t) = (t + 8) i + (t^2 - 8) j + (2t) k is the position of a particle in space at time t. Find the particle's velocity and acceleration vectors. Then write the particle's velocity at t = 1 as a product of its speed and direction. What is the velocity vector? What is the acceleration vector? Write the velocity vector at t = 1 as a product of the speed and direction.
Given, the equation r(t) = (t + 8) i + (t² - 8) j + (2t)
k represents the position of a particle in space at time t.
We need to find the particle's velocity and acceleration vectors.To find the velocity of the particle, we differentiate the given equation with respect to time t as shown below:
v(t) = dr(t) / dt
⇒ v(t) = (1 i + 2t j + 2 k)
For the acceleration of the particle, we differentiate the velocity equation with respect to time t as shown below:
a(t) = dv(t) / dt
⇒ a(t) = 2 j
We can write the velocity of the particle at t = 1 as follows:
v(1) = (1 i + 2 j + 2 k)
Putting t = 1 in the velocity vector, we have:
v(1) = (1 i + 2 j + 2 k)
= √(1² + 2² + 2²) × [i/√5 + 2j/√5 + 2k/√5]
= √9 × u
We can observe that the velocity vector is in the direction of [i/√5 + 2j/√5 + 2k/√5] and its magnitude is √9 = 3 units. Therefore, the velocity vector can be written as a product of its speed and direction as follows:
v(1) = 3[i/√5 + 2j/√5 + 2k/√5]
The velocity vector is given by:
v(t) = (1 i + 2t j + 2 k)
The acceleration vector is given by:
a(t) = 2 j
Therefore, the velocity vector at t = 1 as a product of the speed and direction is:
v(1) = 3[i/√5 + 2j/√5 + 2k/√5]

true or false: using the binomial model with parameters n and p, if we have an integer k such that 0 ≤ k ≤ n, the probability of k successes is the same as the probability of n - k failures.
Using the binomial model with parameters n and p, if we have an integer k such that 0 ≤ k ≤ n,
the probability of k successes is the same as the probability of n - k failures.
This statement is true. Let us understand why: In binomial distribution, we use the following formula for finding the probability of k successes: P(X = k) = nCk pk (1-p)n-k
Here nCk is the binomial coefficient defined as nCk = n!/((n-k)!k!)Since k successes can be obtained in different orders, the binomial coefficient accounts for the different possible combinations.
The probability of (n-k) failures is given by:P(X = n-k) = nC(n-k) pn-k (1-p)k
This can be understood as k failures out of n trials.
The probabilities of k successes and (n-k) failures are equal since the probabilities are calculated in terms of binomial coefficients.

A real number b is a lower bound for the real zeros of f when no real zeros are less than b, and is an upper bound when no real zeros are greater than b.
A real number b is a lower bound for the real zeros of a function f when no real zeros are less than b. In other words, if a real number b is a lower bound, it means that all the real zeros of the function f are greater than or equal to b. So, b sets a limit or boundary below which no real zeros exist.
Similarly, a real number b is an upper bound for the real zeros of a function f when no real zeros are greater than b. If b is an upper bound, it means that all the real zeros of the function f are less than or equal to b. Therefore, b establishes a limit or boundary above which no real zeros exist.

an ordinary (fair) die is a cube with the numbers through on the sides (represented by painted spots). imagine that such a die is rolled twice in succession and that the face values of the two rolls are added together. this sum is recorded as the outcome of a single trial of a random experiment. compute the probability of each of the following events. event : the sum is greater than . event : the sum is not divisible by and not divisible by . round your answers to two decimal places.
The probability of the sum being greater than 7 is 5/18 or 0.28, and the probability of the sum not being divisible by 2 and not being divisible by 3 is 1 or 100%.
To compute the probability of each event,
We need to first find the total number of possible outcomes.
When a die is rolled once, there are six possible outcomes,
(1, 2, 3, 4, 5, or 6)
So when a die is rolled twice, there are 6 × 6 = 36 possible outcomes.
Now, look at each event:
Event 1: The sum is greater than 7.
To find the number of outcomes where the sum is greater than 7, we can list all the possible pairs of rolls that add up to more than 7:
2 + 63 + 54 + 44 + 55 + 35 + 46 + 26 + 36 + 46 + 5There are 10 such outcomes, so the probability of the sum being greater than 7 is 10/36, which simplifies to 5/18 or 0.28.
Event 2: The sum is not divisible by 2 and not divisible by 3.
To find the number of outcomes where the sum is not divisible by 2 and not divisible by 3, we can use a counting technique called the Principle of Inclusion-Exclusion.
First, find the number of outcomes where the sum is not divisible by 2. Half of the possible outcomes have a sum that is even, so the other half (18 outcomes) have a sum that is not divisible by 2.
Next, find the number of outcomes where the sum is not divisible by 3. One-third of the possible outcomes have a sum that is divisible by 3, so two-thirds (24 outcomes) have a sum that is not divisible by 3.
Now, we need to subtract the number of outcomes where the sum is divisible by both 2 and 3 (i.e., divisible by 6). One-sixth of the possible outcomes have a sum that is divisible by 6, so we need to subtract 6 outcomes from our count.
So the total number of outcomes where the sum is not divisible by 2 and not divisible by 3 is 18 + 24 - 6 = 36.
Therefore, the probability of this event is 36/36, which simplifies to 1 or 100%.

2. Use mathematical induction to show that n(n+1)(2n+1) is divisible by 6 for all positive integers n.
The given statement: n(n+1)(2n+1) is divisible by 6 for all positive integers n.
Step-by-step explanation: We need to prove that n(n+1)(2n+1) is divisible by 6 for all positive integers n using mathematical induction.
Step 1: First, lets prove the statement for the smallest possible value of n. The smallest value of n is 1. So, let's check whether the given statement is true for n = 1 or not.
[tex]LHS = 1(1+1)(2*1+1) = 6[/tex]
It is divisible by 6. Hence, the statement is true for n=1.
Step 2: Let's assume that the statement is true for n=k. So, we can say that n(n+1)(2n+1) is divisible by 6 for n=k. i.e., n(n+1)(2n+1) = 6a (for some integer a).
Step 3: We need to prove the statement is true for n=k+1.
So, we need to prove that (k+1){(k+1)+1}[2(k+1)+1] is divisible by 6
Using the assumption we made in step 2.
[tex]LHS = (k+1){(k+2)}[2k+3] = (k+1)(k+2)(2k+3)LHS = (2k+3)k(k+1)(k+2)LHS = 2[k(k+1)(k+2)] + 3[k(k+1)][/tex]
Now, k(k+1)(k+2) is divisible by 6 using the assumption made in step 2.
So, LHS = 2[k(k+1)(k+2)] + 3[k(k+1)] is also divisible by 6.
Hence, the statement is true for n=k+1.
Step 4: Using steps 1 to 3, we can say that the given statement is true for n=1 and if it is true for n=k, then it is also true for n=k+1.
Hence, by mathematical induction, we can say that the statement is true for all positive integers n.
Hence, it is proved that n(n+1)(2n+1) is divisible by 6 for all positive integers n.

To find the volume of the solid generated by revolving the region bounded by the graphs of the equations about the x-axis,
Use the method of cylindrical shells.
The region bounded by the graphs of the equations is the area between the curve y = 3/x and the x-axis, bounded by x = 1 and x = 3.
To find the volume, integrate the circumference of each cylindrical shell multiplied by its height over the interval [1, 3].

Evaluate the following as true or false. dx /dy = 1/dy/dx = 0, then the tangent line to the curve y = f(x) is horizontal.
True, If [tex]\frac{dx}{dy} = \frac{1}{\frac{dx}{dy} } = 0[/tex], then the tangent line to the curve y = f(x) is horizontal.
To determine if the tangent line to the curve y = f(x) is horizontal, we need to analyze the derivative of y with respect to x, dy/dx.
We know that dx/dy = 1/dy/dx = 0, let's examine what this means for the tangent line:
1. dx/dy = 0:
This implies that the change in x with respect to y is zero. In other words, as y changes, x remains constant. This suggests that the curve is vertical, with the x-coordinate fixed for all values of y.
2. 1/dy/dx = 0:
This indicates that the reciprocal of the derivative of y with respect to x is zero. Since the derivative of y with respect to x represents the slope of the tangent line, a zero reciprocal slope implies a horizontal tangent line. It means that for small changes in x, the corresponding changes in y are negligible.
Considering both conditions, we conclude that the tangent line to the curve y = f(x) is horizontal. This means that the slope of the tangent line is zero, indicating a constant y-coordinate as x changes.
A horizontal tangent line suggests that the function f(x) has a flat portion at the specific x-value where the tangent line is drawn. This occurs when the rate of change of y with respect to x is zero, resulting in a constant value for y.
Hence, based on the given conditions dx/dy = 1/dy/dx = 0, we can determine that the tangent line to the curve y = f(x) is indeed horizontal.

The function [tex]\( f(x) = \sin(x) \cos(x) + 6 \)[/tex] is increasing on the intervals [tex]\( 0 < x < \frac{\pi}{2} \)[/tex] and [tex]\( \pi < x < \frac{3\pi}{2} \).[/tex]The function [tex]\( f(x) = \sin(x) \cos(x) + 6 \)[/tex] is decreasing on the intervals [tex]\( \frac{\pi}{2} < x < \pi \)[/tex] and [tex]\( \frac{3\pi}{2} < x < 2\pi \).[/tex]To find the intervals on which the function is increasing or decreasing, we need to determine the sign of the derivative of the function.
First, let's find the derivative of the function [tex]\( f(x) = \sin(x) \cos(x) + 6 \)[/tex]:
[tex]\( f'(x) = (\cos(x) \cos(x) - \sin(x) \sin(x)) = \cos^2(x) - \sin^2(x) \)[/tex]
Next, we can simplify the derivative:
[tex]\( f'(x) = \cos^2(x) - (1 - \cos^2(x)) = 2\cos^2(x) - 1 \)[/tex]
Now, we need to determine the sign of [tex]\( f'(x) \)[/tex] to identify the intervals of increase or decrease.
[tex]For \( f'(x) \), when \( 2\cos^2(x) - 1 > 0 \), we have \( \cos^2(x) > \frac{1}{2} \).[/tex]
From the unit circle, we know that [tex]\( \cos(x) > 0 \)[/tex] when [tex]\( 0 < x < \frac{\pi}{2} \)[/tex]and [tex]\( \pi < x < \frac{3\pi}{2} \).[/tex]
Therefore, on the intervals [tex]\( 0 < x < \frac{\pi}{2} \)[/tex] and [tex]\( \pi < x < \frac{3\pi}{2} \)[/tex], the function is increasing.
On the interval [tex]\( \frac{\pi}{2} < x < \pi \)[/tex] and [tex]\( \frac{3\pi}{2} < x < 2\pi \), \( \cos(x) < 0 \)[/tex], so [tex]\( 2\cos^2(x) - 1 < 0 \).[/tex]
Therefore, on these intervals, the function is decreasing.
In summary:
The function [tex]\( f(x) = \sin(x) \cos(x) + 6 \)[/tex] is increasing on the intervals [tex]\( 0 < x < \frac{\pi}{2} \)[/tex] and [tex]\( \pi < x < \frac{3\pi}{2} \).[/tex]
The function [tex]\( f(x) = \sin(x) \cos(x) + 6 \)[/tex] is decreasing on the intervals [tex]\( \frac{\pi}{2} < x < \pi \)[/tex] and [tex]\( \frac{3\pi}{2} < x < 2\pi \).[/tex]

If F(x)=13x/(4+x ^2), find F (3) and use it to find an equation of the tangent line to the curve y=13x/(4+x ^2 ) at the point (3,3). F(3)= y(x)=
The answer is F(3) = 9/5
To find F(3), we substitute x = 3 into the given function F(x) = 13x/(4 +[tex]x^2[/tex]). Plugging in x = 3, we have:
F(3) = 13 * 3 / (4 + [tex]3^2[/tex])
= 39 / (4 + 9)
= 39 / 13
= 3
Hence, F(3) = 3.

Show the connection between the slope of a tangent of a function at a given point and its derivative evaluated at that point, using a diagram and derivation steps. \[ [C-5] \]
The slope of a tangent line at a given point is equal to the value of the derivative of the function evaluated at that point.
Let's derive the connection between the slope of the tangent line and the derivative.
Find the slope of the tangent line:
The slope of the tangent line passing through points [tex]P(x_0, f(x_0))[/tex] and [tex]Q(x_0 + h, 0)[/tex] can be calculated using the formula:
slope = (change in y) / (change in x)
= [tex](f(x_0 + h) - f(x_0)) / (h)[/tex]
Evaluate the derivative:
The derivative of the function f(x) at the point [tex]x_0[/tex] is denoted by [tex]f'(x_0)[/tex] or [tex]dy/dx|x=x_0[/tex]. It represents the instantaneous rate of change of the function at that point. To find the derivative, we take the limit as h approaches 0 of the slope formula:
[tex]f'(x_0) = lim(h - > 0) [(f(x_0 + h) - f(x_0)) / h][/tex]
Connection between the slope and the derivative:
By comparing the derivative expression [tex]f'(x_0)[/tex] with the slope formula, we observe that as h approaches 0, the slope of the tangent line approaches the derivative evaluated at [tex]x_0[/tex].
Therefore, the slope of the tangent line is equal to the derivative of the function evaluated at that point:
[tex]slope = f'(x_0)[/tex]
This connection shows that the derivative represents the slope of the tangent line at any given point on the function's graph.
