16 Parametric app
The Parametric app enables you to explore parametric equations. These are equations in which both x and y
are dened as functions of t. They take the forms x = f(t) and y = g(t).
Getting started with the Parametric app
The Parametric app uses the customary app views: Symbolic, Plot, and Numeric view.
The Symbolic view, Plot view, and Numeric view menu buttons are available in this app.
Throughout this chapter, we will explore the parametric equations x(T) = 8sin(T) and y(T) = 8cos(T). These
equations produce a circle.
Opening the Parametric app
Press , and then select Parametric.
The Parametric app starts in Symbolic view. This is the dening view. It is where you symbolically dene (that
is, specify) the parametric expressions you want to explore.
The graphical and numerical data you see in Plot view and Numeric view are derived from the symbolic
functions dened here.
