Topics
We reviewed the derivatives of the six trigonmetric functions (Sec 3.5) and outlined some of the exercises in the WebWork set “Derivatives – Trigonometric.”
We then reviewed functions which are compositions of functions, and introduced the Chain Rule–a differentiation rule of finding the derivatives of such composite functions:

We went through on exercise from the “Derivatives – Chain Rule” WebWork set:

Here is a video which explains the Chain Rule in much the same way as I did in class, and goes through additional examples:
