When the TI
.
83 detects an error, it displays
ERR:
message
and an error menu.
Chapter 1 describes the general steps for correcting errors. This table contains
each error type, possible causes, and suggestions for correction.
Error Type
Possible Causes and Suggested Remedies
ARCHIVED VAR
A function or instruction is archived and therefore cannot
be executed or edited. Use the unarchive command to
unarchive the variable before using it.
ARGUMENT
A function or instruction does not have the correct number
of arguments. See Appendix A and the appropriate chapter.
BAD GUESS
¦
In a
CALC
operation, you specified a
Guess
that is not
between
Left Bound
and
Right Bound
.
¦
For the
solve(
function or the equation solver, you
specified a
guess
that is not between
lower
and
upper
.
¦
Your guess and several points around it are undefined.
Examine a graph of the function. If the equation has a
solution, change the bounds and/or the initial guess.
BOUND
¦
In a
CALC
operation or with
Select(
,
you defined
Left Bound
>
Right Bound
.
¦
In
fMin(
,
fMax(
,
solve(
, or the equation solver, you
entered
lower
‚
upper
.
BREAK
You pressed the
É
key to break execution of a program,
to halt a
DRAW
instruction, or to stop evaluation of an
expression.
DATA TYPE
You entered a value or variable that is the wrong data type.
¦
For a function (including implied multiplication) or an
instruction, you entered an argument that is an invalid
data type, such as a complex number where a real
number is required. See Appendix A and the appropriate
chapter.
¦
In an editor, you entered a type that is not allowed, such
as a matrix entered as an element in the stat list editor.
See the appropriate chapter.
¦
You attempted to store to an incorrect data type, such as
a matrix, to a list.
DIM MISMATCH
You attempted to perform an operation that references
more than one list or matrix, but the dimensions do not
match.
DIVIDE BY 0
¦
You attempted to divide by zero. This error is not
returned during graphing. The TI
.
83 allows for
undefined values on a graph.
¦
You attempted a linear regression with a vertical line.
