The TI
.
83 uses the variables listed below in various ways.
Some variables are restricted to specific data types.
The variables
A through Z and
q
are defined as real or
complex numbers. You may store to them. The TI
.
83 can
update
X, Y, R,
q
, and T during graphing, so you may want
to avoid using these variables to store nongraphing data.
The variables (list names)
L
1
through L
6
are restricted to
lists; you cannot store another type of data to them.
The variables (matrix names)
[A] through [J] are restricted
to matrices; you cannot store another type of data to them.
The variables
Pic1 through Pic9 and Pic0 are restricted to
pictures; you cannot store another type of data to them.
The variables
GDB1 through GDB9 and GDB0 are restricted
to graph databases; you cannot store another type of data
to them.
The variables
Str1 through Str9 and Str0 are restricted to
strings; you cannot store another type of data to them.
You can store any string of characters, functions,
instructions, or variables to the functions
Y
n
, (
1 through 9,
and
0), X
n
T
/Y
n
T
(1 through 6), r
n
(
1 through 6), u(
n
), v(
n
),
and
w(
n
) directly or through the
Y=
editor. The validity of the
string is determined when the function is evaluated.
The variables below must be real numbers. You may store
to them. Since the TI
.
83 can update some of them, as the
result of a
ZOOM
, for example, you may want to avoid
using these variables to store nongraphing data.
