**Product Rule:** Used to find the derivative of the product of the two different functions.

Repeat these words every time you use this rule. The derivative of a product is: "the first times the derivative of the second PLUS the second times the derivative of the first"

d/dx (uv) = u(v') + v(u') |

Find dy/dx for each of the following:

Problem 1:

Problem 2:

**Quotient Rule:** Used to find the derivative of the ratio of two functions.

Repeat these words every time you use this rule. The derivative of a quotient is: "The denominator times the derivative of the numerator MINUS the numerator times the derivative of the denominator ALL OVER the denominator squared."

Problem 3:

Problem 4:
