102 An introduction to HP apps
The zoom options are explained in the following table.
Evaluating
You can step through the table of evaluations in Numeric view by
pressing
= or \. You can also quickly jump to an evaluation
by entering the independent variable of interest in the
independent variable column and tapping .
For example, suppose in the Symbolic view of the Function app,
you have defined F1(X) as (X–1)
2
–3. Suppose further that
you want to know what the value of that function is when X is 625.
1. Open Numeric view (
M).
2. Anywhere in the independent column—the left-most
column—enter 625.
Option Result
In The increment between consecutive values
of the independent variable becomes the
current value divided by the
NUMZOOM
setting. (Shortcut: press +.)
Out The increment between consecutive values
of the independent variable becomes the
current value multiplied by the
NUMZOOM
setting. (Shortcut: press w.)
Decimal Restores the default NUMSTART and NUMSTEP
values: 0 and 0.1 respectively.
Integer The increment between consecutive values
of the independent variable is set to 1.
Trig • If the angle measure setting is radians,
sets the increment between consecutive
values of the independent variable
to /24 (approximately 0.1309).
• If the angle measure setting is degrees,
sets the increment between consecutive
values of the independent variable to
7. 5.
Undo Zoom
Returns the display to the previous zoom, or
if there has been only one zoom, displays
the graph with the original plot settings.
