– moves the leftmost cursor to the

screen’s left edge and moves the rightmost cursor to the screen’s right edge.

–The menu key copies the right plot to the left plot.

3.To un-split the screen, press . The left side takes over the whole screen.

The Plot-Table view gives you two simultaneous views of the plot.

	1.		Press				. Select
			Plot				and
					-Table
			press			. The screen
			displays the plot on the
			left side and a table of
			numbers on the right side.
	2.		To move up and down the table, use the							and
			cursor keys. These keys move the tra.ce point left or
			right along the plot, and in the table, the
			corresponding values are highlighted.
	3.		To move between functions, use the						and
			cursor keys to move the cursor from one graph to
			another.
	4.		To return to a full Numeric (or Plot) view, press
Overlay plots			(or			).
	If you want to plot over an existing plot without erasing
	that plot, then use							Overlay Plot instead of
				. Note that tracing follows only the current
	functions from the current aplet.
Decimal scaling	Decimal scaling is the default scaling. If you have
	changed the scaling to Trig or Integer, you can change it
	back with Decimal.
Integer scaling	Integer scaling compresses the axes so that each pixel is
		1 ⋅ 1 and the origin is near the screen center.
Trigonometric	Use trigonometric scaling whenever you are plotting an
scaling	expression that includes trigonometric functions.
	Trigonometric plots are more likely to intersect the axis at
	points factored by π.
