Parametric app
The Parametric app enables 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 Parametric app uses the customary app views:
Symbolic, Plot and Numeric described in chapter 5.
For a description of the menu buttons available in this
app, see:
• “Symbolic view: Summary of menu buttons” on
page 86
• “Plot view: Summary of menu buttons” on page 96,
and
• “Numeric view: Summary of menu buttons” on
page 104
Throughout this chapter, we will explore the parametric
equations x(T) = 8sin(T) and y(T) = 8cos(T). These
equations produce a circle.

Symbolic view.
This is the defining

specify) the parametric expressions you want to
explore.
