1. OPERATIONS WITH DERIVATIVES

2. The derivative of a constant times a function Justification

3. Example 1 Example 2

4. EXERCISE 1 Calculate the derivative of each of the following functions. Then find the equation of the tangent line at the indicated point.

5. Finding the critical points of a function y=f(x) defined by a formula STEP 1. Find all the points where f ‘(x)=0 or where f ‘ (x) is undefined. These are the candidates to be critical points STEP 2. From the candidate points choose the ones in the domain of the function f(x). Those are the critical points

6. Example 2 Find the critical points of the function Formula for y’(x) Solve – y’(x)=0 – y’(x) undefined Choose the solutions which are in the domain of y(x)

7. Exercise 2 Algebraically, find the critical points for each of the following functions

8. Additive Property of Derivatives

9. Example 3 Main Operation: Addition

10. Derivative of the product of two functions First Function Second Function

11. Exercise 4 Each of the following functions can be represented as the product of functions f and g. Identify the functions and use the the product rule to find its derivative.

12. Derivative of the quotient of two functions

13. EXERCISE 5 Each of the following functions can be represented as the quotient of two functions f and g. Clearly identify them and use the quotient rule to find its derivative. Some of these derivatives can be calculated using previous rules as well. When it is possible you are asked to do it.

15. Applications Work on the applications Work on the practice on computation of derivatives.
