If the intersection is within the display area, the cursor moves to the

intersection and the coordinates of the intersection are displayed near the

bottom left comer of the screen.

If the intersection is not within the display area, the cursor remains where

it is, the message OFF SCREEN is briefly displayed, and the coordinates of

the intersection are displayed near the bottom left comer of the screen.

Tables

If you have chosen to display the coordinates of the cursor while m trace

mode, you can read the coordinates of consecutive plotted points by

pressing the ® or @ key. This is explained in “Cursor movement” on

page 4-35.

You can also display the coordinates of plotted points in tabular form. The

Tables fimction—selected by pressing 0 (TME)—shows the value of the

dependent variable for each value of tlie independent variable within the

range specified on the Plot Window input form. Tire values of the

independent variable are listed in increments determined by the step

value (also specified on the Plot Window input form).

If you have plotted more than one fimction, the values of the independent

variable for each fimction is given, each in a separate column.

Customizing table values

The default values for the independent variable are taken from the

parameters on the Plot Window input form. You can override these

defaults by specifying a different starting value and step increment.

To change the default table values;

1. Press 0 (tESET) to select TABLE SETUP.

The Table Setup input form is displayed.

2. To have the calculator automatically generate the series of values for

the independent variable, specify a starting value and step value.

3. If you want to specify values for the independent variable, choose

BUILD YOUR OWN rather than AUTOMATIC as the type of table.

4. Press 0 (Ible) to select TABLE.

If you chose an automatic table, the table values are redrawn

according to the start and step values you specified.
