On the TI-82 STATS you can enter and use several types of
data, including real and complex numbers, matrices, lists,
functions, stat plots, graph databases, graph pictures, and
strings.
The TI-82 STATS uses assigned names for variables and other
items saved in memory. For lists, you also can create your own
five-character names.
Variable Type Names
Real numbers A, B, . . . , Z, q
Complex numbers A, B, . . . , Z, q
Matrices ãAä, ãBä, ãCä, . . . , ãJä
Lists
L1, L2, L3, L4, L5, L6, and user-defined
names
Functions
Y1, Y2, . . . , Y9, Y0
Parametric equations
X1T and Y1T, . . . , X6T and Y6T
Polar functions
r1, r2, r3, r4, r5, r6
Sequence functions u, v, w
Stat plots Plot1, Plot2, Plot3
Graph databases GDB1, GDB2, . . . , GDB9, GDB0
Graph pictures Pic1, Pic2, . . . , Pic9, Pic0
Strings Str1, Str2, . . . , Str9, Str0
System variables Xmin, Xmax, and others
• You can create as many list names as memory will allow
(Chapter 11).
• Programs have user-defined names and share memory with
variables (Chapter 16).
• From the home screen or from a program, you can store to
matrices (Chapter 10), lists (Chapter 11), strings (Chapter
15), system variables such as
Xmax (Chapter 1), TblStart
(Chapter 7), and all Y= functions (Chapters 3, 4, 5, and 6).
• From an editor, you can store to matrices, lists, and
Y= functions (Chapter 3).
• From the home screen, a program, or an editor, you can store
a value to a matrix element or a list element.
• You can use
DRAW STO menu items to store and recall
graph databases and pictures (Chapter 8).
