Setting Up the Table
To display the table setup editor, select TBLST from the
TABLE menu. The screen to the right shows the default
table setup settings.
TblStart specifies the first independent variable value ( x , q ,
or t ) in the table (only when Indpnt: Auto is selected).
@ Tbl (table step) specifies the increment or decrement from one independent variable value
to the next independent variable value in the table.
♦
If @ Tbl is positive, then the values of x , q , or t increase as you scroll down the table.
♦
If @ Tbl is negative, then the values of x , q , or t decrease as you scroll down the table.
Indpnt: Auto displays independent variable values automatically in the first column of the table,
starting at TblStart .
Indpnt: Ask displays an empty table. As you enter x values in the x= prompt ( x= value b),
each value is added to the independent variable column and the corresponding dependent
variable values are calculated and displayed. When
Ask is set, you cannot scroll beyond the six
independent variable values that are currently displayed in the table.
To display the table using the
current table setup settings,
select TABLE from the
TABLE
menu.
TblStart and @ Tbl must be
real numbers; you can enter
an expression.
In DifEq graphing mode,
it is a good practice to set
TblStart
= tMin and
@ Tbl = tStep.
