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
(
includin
g
implied multiplication
)
or an
instruction, you entered an ar
g
ument 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 durin
g
g
raphin
g
. The TI.83 allows for
undefined values on a graph.
¦You attempted a linear regression with a vertical line.
