# type and the error menu.

Chapter 1 describes how to correct an error. This section describes possible causes for the
errors and examples. To find the proper arguments for a function or instruction, as well as
restrictions on those arguments, refer to Chapter 20: A to Z Function and Instruction Reference.

01 OVERFLOW

You attempted to enter a number that is beyond the calculator’s range.

You attempted to execute an expression with a result that is beyond the
calculator’s range.

02 DIV BY ZERO

You attempted to divide by zero.

You attempted a linear regression with a vertical line.

03 SINGULAR MAT

You attempted to use a singular matrix (determinate = 0) as the argument
for

L

1

,

Simult

, or

LU

.

You attempted a regression with at least one inappropriate list.

You attempted to use a matrix with repeated eigenvalues as the argument
for

exp

,

cos

, or

sin

.

04 DOMAIN

You attempted to use an argument that is out of the range of valid values
for the function or instruction.

You attempted a logarithmic or power regression with a

Lx or an

exponential regression with a

Ly.

05 INCREMENT

The increment in

seq

is

0

or has the wrong sign; the increment for a loop is

0

.

06 BREAK

You pressed ^ to break a program,

DRAW

instruction, or expression evaluation.

07 SYNTAX

You entered a value; look for misplaced functions, arguments, parentheses, or
commas; check the syntax description in the A to Z Reference.

Errors 1 through 5 do not
occur during graphing. The
TI

-

86 allows for undefined

values on a graph.
