Objectives: In this tutorial, we define parametric equations in the
plane. We illustrate how to draw the graph of parametric equations.
After working through these materials, the student should be able
to graph a system of parametric equations.
Modules:
Definition.Parametric Equations in the plane is a pair of functions
x = f(t) and y = g(t)
which describe the x and y coordinates of the graph of some curve in the plane.
