Parametric aplet
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 x = f{t) and
y = g(t).
Getting started with the Parametric aplet
The following example uses the parametric equations
x(i) = 3sinf
y(r) = 3cosf
Note: This example will produce a circle. For this example to
work, the angle measure must he set to degrees.
