Chain Rule
The chain rule is often referred to as the function of a function rule.
The key identifier to seeing when you should use this rule is to notice brackets with a power.
The saying you can use to help you remember how to use this rule is: The derivative of the outside, times the derviative of the inside. In this regard you treat it like a large power rule, and then multiply by the derivative of the inside piece.
The chain rule is also very useful when dealing with rational functions with single constants on the numerator.
