Defining and Selecting Functions
in the Y= Editor &
To create a table of values for a function, you first must define
the function in the Y= editor. Press & to display the Y= editor;
then define up to four functions, Y1, Y2, Y3, and Y4, in terms of
the independent variable, X.
For every selected function in the Y= editor, the calculator
automatically creates a column of Yn values. Because the
Y= editor holds up to four functions, the TIN73 can create up
to four Yn columns in a table, one for each function.
When you first enter a function, it is selected automatically. To
select or deselect a function, highlight the = with the cursor,
and then press b.
For more details on entering functions, see Chapter 9:
Function Graphing.
