Computing Derivatives

Derivative of a Product of Functions

Use the product rule whenever there is a function that's a product of two other functions of x. If

f(x) = ({something with an x}) × ({something else with an x}),

then use the product rule to find f'.

To use the product rule, figure out which two functions are multiplied together, and the derivative of each of those functions.
