HP Prime Graphing NW280AAABA manual Evaluating

The zoom options are explained in the following table.

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

Undo Zoom

•If the angle measure setting is radians, sets the increment between consecutive values of the independent variable

to π/24 (approximately 0.1309).

•If the angle measure setting is degrees, sets the increment between consecutive values of the independent variable to 7.5.

Returns the display to the previous zoom, or if there has been only one zoom, displays the graph with the original plot settings.

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.
