Operation Manual

Chapter 7: Tables 118
TblStart, @Tbl
TblStart (table start) defines the initial value for the independent variable. TblStart applies only when
the independent variable is generated automatically (when Indpnt: Auto is selected).
You can adjust TblStart and @Tbl while in the Table screen. Independent and dependent variables vary
with Func mode settings (X, T, q,n). For example, select an X value in the X column, press + and edit the
@Tbl value. The table will update and the cursor will be on the new TblStart
X value.
@Tbl (table step) defines the increment for the independent variable.

Setting Up the Table from the Home Screen or a Program
To store a value to TblStart, @Tbl, or TblInput from the home screen or a program, select the variable
name from the VARS TABLE secondary menu. TblInput is a list of independent-variable values in the
current table.
When you press y - in the program editor, you can select IndpntAuto, IndpntAsk,
DependAuto, and DependAsk.
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.
Selections Table Characteristics
Indpnt: Auto
Depend: Auto
Values are displayed automatically in both the independent-
variable column and in all dependent-variable columns.
Indpnt: Ask
Depend: Auto
The table is empty. When you enter a value for the
independent variable, all corresponding dependent-variable
values are calculated and displayed automatically.
Indpnt: Auto
Depend: Ask
Values are displayed automatically for the independent
variable. To generate a value for a dependent variable, move
the cursor to that cell and press Í.
Indpnt: Ask
Depend: Ask
The table is empty; enter values for the independent variable.
To generate a value for a dependent variable, move the
cursor to that cell and press Í.
