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
.
