Chapter 7: Tables 117
Defining the Dependent Variables
Defining Dependent Variables from the Y= Editor
In the Y= editor, enter the functions that define the dependent variables. Only functions that are
selected in the Y= editor are displayed in the table. The current graphing mode is used. In
parametric mode, you must define both components of each parametric equation (Chapter 4).
Editing Dependent Variables from the Table Editor
To edit a selected Y= function from the table editor, follow these steps.
1. Press y 0 to display the table, then press ~ or | to move the cursor to a dependent-
variable column.
2. Press } until the cursor is on the function name at the top of the column. The function is
displayed on the bottom line.
3. Press Í. The cursor moves to the bottom line. Edit the function.
4. Press Í or †. The new values are calculated. The table and the Y= function are updated
automatically.
Note: You also can use this feature to view the function that defines a dependent variable
without having to leave the table.
