Derivatives using First Principles

Today we took a second look at how we find the derivative of a function with respect to 'x'.  We used the First Principles def'n (ie. the difference quotient from chapter 1) to find the equation of the derivative in general.

We also investigated the idea behind where a function can be differentiable.  Be sure to re-read the examples in section 2.1 along with the lesson notes below to get a true picture of what has been covered.

HOMEWORK:  Again from Section 2.1:  Page 73 - 74, #'s 1, 3, 13 and 14

Also, it might help to read ahead into section 2.2 as we will begin looking at the differentiation rules starting tomorrow in class.
