Rates of Change
Introduction.

Although the title of this chapter reads Limits, Rates of Change and Derivatives,   we will start with

looking at

rates of change

first. You will see that   an exploratory look at the concept of rate of change will make us realize

that we need to explore the idea of a

limit of a function

further. The last section in this chapter will introduce you to the concept of a

derivative of a function.
