IV-Window Memory

You can store up to six sets of V-Window settings in V-Window memory for recall when you need them.

STo store V-Window settings

1.From the Main Menu, enter the GRAPH mode.

2.Press (V-WIN) to display the V-Window setting screen, and input the values you want.

3.Press (STO) to display the pop-up window.

4.Press a number key to specify the V-Window memory where you want to save the settings, and then press U. Pressing @Ustores the settings in V-Window Memory 1 (V-Win1).

STo recall V-Window memory settings

1.From the Main Menu, enter the GRAPH mode.

2.Press (V-WIN) to display the V-Window setting screen.

3.Press (RCL) to display the pop-up window.

4.Press a number key to specify the V-Window memory number for the settings you want to recall, and then press U. Pressing @Urecalls the settings in V-Window Memory 1 (V-Win1).

ISpecifying the Graph Range

You can define a range (start point, end point) for a function before graphing it.

1.From the Main Menu, enter the GRAPH mode.

2.Make V-Window settings.

3.Specify the function type and input the function. The following is the syntax for function input.

Function	( [ ) Start Point End Point			( ] )
4. Draw the graph.
Example	Graph y = x2 + 3x – 2 within the range – 2 x 4.
	Use the following V-Window settings.
	Xmin = –3,	Xmax = 5,	Xscale = 1
	Ymin = –10,	Ymax = 30,	Yscale = 5
