HP 49g Graphing Calculator - Manual (Page 108)

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 ( t ESET) 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
(I ble ) to select
TABLE.
If you chose an automatic table, the table values are redrawn
according to the start and step values you specified.
