MAT 1221 Survey of Calculus Section 2.4 The Product and Quotient Rules

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

Recall: Sum and Difference Rule If, then

However,… If, then

Example 1(a)

Example 1(b)

However,… If, then

Correct Formulas???

Product Rule If, then

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

Expectation Show the “formula” step

Example 3

Remark Should we use the product rule?

Quotient Rule If then

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

Expectation Show the “formula” step

Example 5

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

Example 7

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