Note that in this lesson we show examples, but not any
proof that the formulas for the
product and quotient rules are correct.
A Modified Power Rule (The Chain Rule):
 If , then after first multiplying
We can then find the derivative by

In order to get the derivative, we first rewrite this as
Calculate the derivatives of each function. Write in
fraction form, if needed, so that all exponents are positive in your final answer. Use the "modified power rule" for each.
