The Chain Rule</p><p>Perhaps the best way to introduce this new differentiating technique is to show you the types of functions that would require its use.

Nested Product/Quotient and Chain Rules</p><p>Lastly, we will see how the Chain Rule can be used in conjunction with the Product and Quotient Rules. It takes a bit more planning and organization to take the derivative correctly, but it’s really not too bad. Furthermore, there is a special technique used to simplify these answers. </p><p>Example 9: Differentiate and simplify .</p><p>Example 10: Differentiate and simplify .
