Appendix B: General Information 169
Error Conditions
When the TI-84 Plus detects an error, it returns an error message as a
menu title, such as
ERR:SYNTAX or ERR:DOMAIN. This table contains
each error type, possible causes, and suggestions for correction. The error
types listed in this table are each preceded by ERR: on your graphing
handheld display. For example, you will see
ERR:ARCHIVED as a menu
title when your graphing handheld detects an ARCHIVED error type.
Error Type Possible Causes and Suggested Remedies
ARCHIVED
You have attempted to use, edit, or delete an
archived variable. For example, the expression
dim(L1) produces an error if L1 is archived.
ARCHIVE FULL You have attempted to archive a variable and there
is not enough space in archive to receive it.
ARGUMENT
A function or instruction does not have the correct
number of arguments. See Appendix A for function
and instruction syntax.
Appendix A displays the arguments and punctuation
needed to execute the function or instruction. For
example, stdDev(list[,freqlist]) is a function of the
TI-84 Plus. The arguments are shown in italics. The
arguments in brackets are optional and you need
not type them. You must also be sure to separate
multiple arguments with a comma (,). For example,
stdDev(list[,freqlist]) might be entered as stdDev(L1)
or stdDev(L1,L2) since the frequency list or freqlist is
optional.
BAD ADDRESS
You have attempted to send or receive an
application and an error (e.g. electrical interference)
has occurred in the transmission.
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.
