Derivative of cot^4(x/2)

Curated and Reviewed by Lesson Planet

Apply the chain rule, the power rule, and the derivative of a trigonometric function all in one. Using a function raised to a power, the 14th video in a series of 31 shows how several rules work together to find a derivative. The examples use the power rule and the chain rule to simplify the derivative of the cotangent function raised to a power.
