The applicable set of View Window parameter values is applied as soon as you select a quick zoom command on the Graph window’s [Zoom] menu.

Tip

•Any View Window parameter that is not shown in the above table is unchanged when you execute a quick zoom command.

•When the angle unit setting is degrees, Quick Trig configures the following values.

xmin = –540,

xmax = 540,

xscale = 90

ymin = –1.6,

ymax = 1.6,

yscale = 0.5

kUsing Other Zoom Menu Commands

The [Auto], [Original], [Square], [Round], [Integer], and [Previous] zoom commands are executed as soon as you tap one of them on the Graph window’s [Zoom] menu.

For information about what each command does, see “Zoom Commands” on page 3-2-6.

Tip

•For auto zoom, you can tap the R button instead of using the [Zoom] - [Auto] menu command.

•With Integer Zoom, tap T and then use the stylus to drag the screen image so the part you want to zoom is in the center of the screen.
