2. Objectives
Find the derivative of a trigonometric function using the Chain Rule.

3. Derivative formulas include the chain rule!

4. Examples: Find the derivative

5. Example: Find the derivative

6. Example: Find the derivative

7. Example: Find the derivative

8. Example: Find the derivative

9. Example: Find the derivative

10. Another example:
It looks like we need to use the chain rule again!
derivative of the
outside function
derivative of the
inside function

11. Another example:
The chain rule can be used more than once.
(That’s what makes the “chain” in the “chain rule”!)

12. Example: Find the derivative
