Texas Instruments TI-80 - Defining the Dependent Variable

6-4 Tables
The selected functions from the Y= list define the dependent variables. You can
have as many dependent variables as there are functions in the current graphing
mode (four for FUNC mode and six for PARAM mode).
Enter the functions to define the dependent variables in the
Y=
editor.

Mode
In
PARAM
mode, you must define both components of the
parametric equation (Chapter 5).
Only functions that are selected are displayed in the table.
(When
=
is highlighted, the function is selected.) You can
select and deselect functions from the
Y=
list, from the Home
screen, or from a program. (Refer to page 4
