The Chain Rule

The chain rule helps find derivatives of functions inside other functions.

How the Idea Works

The chain rule is used when one rule is nested inside another. It is like following links in a chain of changes.

Why It Helps

If an outside part changes and an inside part changes, the chain rule combines them. It is one of the most used derivative rules.

Did You Know?

The Chain Rule may sound advanced, but it is built from smaller ideas like patterns, slopes, totals, and careful reasoning.
