Quick example

The following example uses all six app views and should give you an idea of the typical workflow involved in working with an app. The Polar app is used as the sample app.

Open the app

1.Open the Application Library by pressing I.

2.Tap once on the icon of the Polar app. The Polar app opens in Symbolic View.

Symbolic view

The Symbolic view of the Polar app is where you define or specify the polar equation you want to plot and explore. In this example we will plot and explore the equation r = 4π cos (θ ⁄ 2) cos (θ)2 .

3.Define the equation r = 4π cos (θ ⁄ 2) cos (θ)2 by entering:

4Szf n2>>f >jE

(If you are using algebraic entry mode, you would enter 4Szf

n2>f

>jE.)

This equation will draw symmetrical petals provided that the angle measure is set to radians. The angle measure for this app is set in the Symbolic Setup view.
