Reading and Video Assignment #4

In section 1.4 we defined the derivative  of a function at x to be the slope of the tangent line to the given function at x. In section 1.5, we will continue exploring this idea and look at the derivative as a function as well. The following videos illustrate how we will use the idea of "local linearity" to explore the derivatives of functions.
