Understanding Derivatives of Inverse Functions

This video tutorial explains how to find the derivative of an inverse function. It begins with an introduction to the concept and the formula used for calculation. The video then delves into understanding inverse relations and how coordinates are switched. It provides a detailed walkthrough of calculating derivatives using both a formula and implicit differentiation. Finally, an example problem is solved to reinforce the concepts learned.

What is the formula for the derivative of an inverse function?

• 1 over the derivative of the original function

• The derivative of the original function

• The square of the original function

• The inverse of the original function
