This resource is designed to help you understand and master the calculus concepts covered in this worksheet, including derivatives, integrals, and applications of these concepts. We'll provide clear, step-by-step solutions along with explanations to ensure you grasp the underlying principles.
Understanding the HSS CP A1 Worksheet 3
The HSS CP A1 Worksheet 3 focuses on the following key topics:
- Finding derivatives of functions involving trigonometric, exponential, and logarithmic functions.
- Evaluating definite integrals using the fundamental theorem of calculus and substitution method.
- Applying derivatives to find maximum and minimum values of functions on closed intervals.
- Using integrals to find areas under curves and volumes of revolution.
Derivatives: Rules and Applications
Let's start by reviewing the rules of differentiation and applying them to find derivatives of functions. Remember the product rule, quotient rule, and chain rule? We'll use these rules to tackle problems involving trigonometric, exponential, and logarithmic functions.

Example 1: Finding the derivative of y = sin(3x)cos(2x)
To find the derivative of this function, we'll use the product rule. The result is y' = 3cos(3x)cos(2x) - 2sin(3x)sin(2x).
Integrals: Fundamental Theorem and Substitution Method
Now let's move on to integrals. We'll first apply the fundamental theorem of calculus to evaluate definite integrals and then use the substitution method to tackle more complex integrals.
Example 2: Evaluating ∫(x^2 + 2x + 1) dx
To evaluate this integral, we'll first find the antiderivative of the integrand, which is (x^3/3 + x^2 + x). Then, we'll apply the fundamental theorem of calculus to find the definite integral.

Applications of Derivatives and Integrals
In this section, we'll apply derivatives and integrals to solve real-world problems, such as finding maximum and minimum values of functions, areas under curves, and volumes of revolution.
Example 3: Finding the maximum value of f(x) = x^3 - 6x^2 + 9x - 8 on the interval [1, 4]
To find the maximum value, we'll first find the critical points by setting the derivative equal to zero and solving for x. Then, we'll evaluate the function at these critical points and the endpoints of the interval to find the maximum value.
