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.

Instructional Ideas

• Have pupils calculate each of the derivatives needed in the problem in a separate section when working on problems

Classroom Considerations

• Individuals should know the derivative of all six trigonometric functions
• The class should be familiar with applying the chain rule

• This video is hosted on YouTube

Pros

• Shows examples of simpler versions of the complex function
• Includes each of the steps in determining the derivative

Cons

• None
