To un-split the screen, press over the whole screen. . The left side takes The Plot-Table view gives you two simultaneous views of the plot. 1. Press . Select Plot-Table and 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 (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 is the default scaling. If you have changed the scaling to Trig or Integer, you can change it back with Decimal. Integer scaling compresses the axes so that each pixel is 1 × 1 and the origin is near the screen center. Use trigonometric scaling whenever you are plotting an expression that includes trigonometric functions. Trigonometric plots are more likely to intersect the axis at points factored by π. 2-15
