Polar app 275

Polar app

The Polar app enables you to explore polar equations.

Polar equations are equations in which r—the distance a

point is from the origin: (0,0)—is defined in terms of , the

angle a segment from the point to the origin makes with

the polar axis. Such equations take the form .

Getting started with the Polar app

The Polar app uses the six standard app views described

in chapter 5, “An introduction to HP apps”, beginning on

page 69. That chapter also describes the menu buttons

used in the Polar app.

Throughout this chapter, we will explore the expression

5cos(/2)cos()

Open the

Polar app

1. Open the Polar

app:

Select Polar

The app opens in

Symbolic view.

Define the

function

There are 10 fields for defining polar functions. These are

labelled R1() through R9() and R0().

2. Highlight the field you want to use, either by tapping

on it or scrolling to it. If you are entering a new

function, just start typing. If you are editing an

existing function, tap

and make your changes.

When you have finished defining or changing the

function, press
