Applications of Derivative Rules:
1. Applying the Power Rule (Finding derivatives of power functions in various forms e.g. rational exponents)
2. Finding the Equation of a Tangent Line Using the Power Rule
3. Derivatives of Polynomial Functions: Applying the Basic Derivative Rules (Example 1)
4. Derivatives of Polynomial Functions: Applying the Basic Derivative Rules (Example 2)
5. Derivatives of Polynomial Functions: Finding the Equation of a Tangent Line (Example)
6. Derivatives of Polynomial Functions: Finding the Tangent Points for a Given Slope (Example)
7. Application of Derivative Rules (Equation of a Tangent Line and Coordinates of Horizontal Tangent Line)
Note: Keep slopes and coordinates in fractional form, not in decimal form!
8. Problem Solving Using Derivative Rules
Note: - Velocity function is the derivative function of the displacement function.
- Acceleration function if the derivative function of the velocity function.
- Answers in these cases can be in decimal form.
