3-1 Storing Functions

Use the Graph Editor window to store a Graph & Table application function. This section covers Graph Editor operations, and explains how to store functions.

Using Graph Editor Sheets

The Graph Editor window has five tabbed sheets named Sheet 1 through Sheet 5, each of which can contain up to 20 functions. You can graph up to 20 functions simultaneously, as long as all of the functions are on the same sheet.

The table below explains Graph Editor sheet operations.

To do this:	Do this:
Select a sheet	Tap the tab of the sheet you want to select. The currently selected sheet is the
	“active” sheet.
Rename a sheet	Tap the tab of the active sheet. On the dialog box that appears, enter up to 8
	bytes for the sheet name, and then tap [OK].
Return the active sheet	Tap a, [Sheet], and then [Default Name].
name to its initial default
Initialize a Sheet	Tap a, [Sheet], and then [Clear Sheet]. This clears all of the active sheet
	functions and renames the sheet to its default name.
Initialize all the Sheets	Tap [Edit], and then [Clear All]. In response to the confirmation dialog box that
	appears, tap [OK]. This clears all of the expressions from the Graph Editor
	window and returns the sheet names to their initial default names (Sheet 1
	through Sheet 5).

Storing a Function

To input an expression, tap a blank line on the Graph Editor window and then perform the operations described below.

To input this type of	Do this:
expression:
Rectangular coordinate	1.	Tap [Type] - [y=Type].
expression (y = f(x))	2.	Input an expression (such as: 2x2 – 3) that
		contains variable x and then press E.
Polar coordinate	1.	Tap [Type] - [r=Type].
expression	2.	Input an expression (such as: 5sin(3)) that
		contains variable  and then press E.
Parametric expressions	1.	Tap [Type] - [ParamType].
	2.	In the xt =, yt = lines, input expressions that
		each contain t (such as: 3sin(t), 3cos(t)), and
		then press E.
