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
k Using 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.
