1. MAT 1221 Survey of Calculus Section 2.4 The Product and Quotient Rules http://myhome.spu.edu/lauw

2. Expectations Use equal signs. Show necessary steps. Double check your calculator calculations.

3. Recall: Sum and Difference Rule If, then

4. However,… If, then

5. Example 1(a)

6. Example 1(b)

7. However,… If, then

8. Correct Formulas???

9. Product Rule If, then

10. Example 2 (1(a)) Verify the Product Rule

11. Expectation Show the “formula” step

12. Example 3

13. Remark Should we use the product rule?

14. Quotient Rule If then

15. Example 4 (1(b)) Verify the Quotient Rule

16. Expectation Show the “formula” step

17. Example 5

18. Remarks Sometimes, it is easier to NOT use the quotient rule

19. Example 7

20. Expectations Must show the “formula” step Double check your algebra!!! Read the hints Use equal signs
