Shirley Kolmer of Saint Louis University, whose many talents included dry wit, once said to our graduate class in number theory, “Primes tend to be odd.” Similarly, animations tend to be plots. In this chapter, you will learn to plot functions of one and two variables, curves and surfaces represented by parametric equations, and individual points. You will also learn many optional features by which you can produce a high-quality plot that suits your needs and conforms to your preferences. These options will be your artist’s brushes.
