Sample Questions and Solutions

In this section, we present a selection of sample questions from the AP Calculus Unit 5 test, along with detailed solutions and explanations. These questions are designed to provide a comprehensive review of the key concepts and skills covered in the unit, and to help students identify common pitfalls and misconceptions.

Question 1: Derivatives of Inverse Trigonometric Functions

Find the derivative of the function 𝑓(𝑥) = sin ⁻¹(2𝑥 − 1).

Solution:

• Using the chain rule, we have: $$f'(x) = \fracddx \sin^-1(2x-1) = \frac1\sqrt1-(2x-1)^2 \cdot \fracddx (2x-1) = \frac2\sqrt4x^2-4x+2$$

Question 2: Integrals of Rational Functions

Evaluate the integral ∫(x ²+ 2x – 3)/(x ²– 1) dx.

Solution:

• Using partial fraction decomposition, we can write: $$\fracx^2 + 2x – 3x^2 – 1 = \fracAx+1 + \fracBx-1$$
• Solving for A and B, we get: A = 2 and B = -1.
• Therefore, the integral becomes: $$\int\fracx^2 + 2x – 3x^2 – 1 dx = \int\left(\frac2x+1 – \frac1x-1\right) dx = 2\ln|x+1| – \ln|x-1| + C$$

Question 3: Applications of Integrals

A rectangular garden is to be enclosed by a fence on three sides, with the fourth side being a wall of a building. If the garden is 100 feet long and 50 feet wide, find the area of the largest possible garden that can be enclosed with 150 feet of fencing.

Solution:

• Let x be the width of the garden. Then the length of the garden is 100 – x.
• The perimeter of the garden is given by: $$P = x + 2(100-x) = 200 – x$$
• Since we have 150 feet of fencing, we have: $$200 – x = 150 \Rightarrow x = 50$$
• Therefore, the width of the garden is 50 feet, and the length is 100 – 50 = 50 feet.
• The area of the garden is: $$A = x(100-x) = 50(50) = 2500 \text square feet$$

Question 4: Sequences and Series, Ap calculus unit 5 test answers

Determine whether the series ∑ _n=1^∞(n ²+ 1)/(n ³+ 2) is convergent or divergent.

Solution:

• Using the limit comparison test with the series ∑ _n=1^∞1/n, we have: $$\lim_n\to\infty \fraca_nb_n = \lim_n\to\infty \fracn^2 + 1n^3 + 2 \cdot \fracn1 = \lim_n\to\infty \fracn^3+n^2n^3+2n = 1$$
• Since the limit is finite and nonzero, and the series ∑ _n=1^∞1/n is convergent (it is a p-series with p = 1 > 0), the series ∑ _n=1^∞(n ²+ 1)/(n ³+ 2) is also convergent by the limit comparison test.
