ZOOM options	The following table lists the zoom options:

		Option	Meaning

		In	Decreases the intervals for the
			independent variable so a narrower
			range is shown. Uses the NUMZOOM
			factor in Numeric Setup.
		Out	Increases the intervals for the
			independent variable so that a
			wider range is shown. Uses the
		Decimal	NUMZOOM factor in Numeric Setup.
		Decimal	Changes intervals for the
			independent variable to 0.1 units.
			Starts at zero. (Shortcut to changing
		Integer	NUMSTART and NUMSTEP.)
		Integer	Changes intervals for the
			independent variable to 1 unit.
			Starts at zero. (Shortcut to changing
		Trig	NUMSTEP.)
		Trig	Changes intervals for independent
			variable to π/24 radian or 7.5
			degrees or 81/3 grads. Starts at
			zero.
		Un-zoom	Returns the display to the previous
			zoom.
	The display on the right is a Zoom In of the display on the
	left. The ZOOM factor is 4.

H I N T	To jump to an independent variable value in the table,
	use the arrow keys to place the cursor in the independent
	variable column, then enter the value to jump to.
Automatic	You can enter any new value in the X column. When you
recalculation	press		, the values for the dependent variables are
			and the entire table is regenerated with the
	recalculated,
	same interval between X values.

2-18	Aplets and their views
