WebWork

The 2nd WebWork set “Derivatives – Functions” is due Monday (Sept 30). We did some examples from that assignment in class–see below.

We went through some examples from “Derivatives – Functions” where we calculate f'(x) for a given function f(x) using the limit definition.

We then introduced some of the rules for differentiation (i.e., rules for finding the derivative) which are based on the limit definition, but which will allow us to calculate derivates without having the use the limit definition. In particular, the Power Rule will be important–look at some examples in Sec 3.3 which use the Power Rule!
