About the Parametric aplet
The Parametric aplet 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 aplet
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.
