About the Parametric app
The Parametric app allows you to explore parametric
equations. These are equations in which both x and y are
defined as functions of t. They take the forms
and .
Getting started with the Parametric app
The following example uses the parametric equations
Note: this example will produce a circle. For this example
to work, the angle measure must be set to degrees.
