DIVIDE BY 0
¦
You are attempting to divide by zero. This error does not
occur during graphing. The TI
.
82 allows for undefined
values on a graph.
¦
You are attempting a linear regression with a vertical line.
DOMAIN
¦
The argument to a function or instruction is out of the
valid range. See Appendix A and the appropriate chapter.
This error does not occur during graphing. The TI
.
82
allows for undefined values on a graph.
¦
You are attempting a logarithmic or power regression with
a
M
X
or an exponential regression with a
M
Y
.
Duplicate Name
Unable to transmit item because a variable with that name
already exists in receiving unit.
Error in Xmit
¦
Unable to transmit item. Check to see that the cable is
firmly connected to both units and that the receiving unit
is in
Receive
mode.
¦ É
was used to break during transmission.
ILLEGAL NEST
You are attempting to use an invalid function in an argument
to a function; for example,
seq(
within
expression
for
seq(
.
INCREMENT
¦
The increment in
seq(
is
0
or has the wrong sign. This
error does not occur during graphing. The TI
.
82 allows for
undefined values on a graph.
¦
The increment for a loop is
0
.
INVALID
You are attempting to reference a variable or use a function
in a place where it is not valid. For example,
Y n
cannot
reference
Y
,
Xmin
,
@
X
or
TblMin
.
INVALID DIM
¦
The dimension of the argument is not appropriate for the
operation.
¦
Matrix element dimensions and list element dimensions
must be integers between 1 and 99.
¦
A matrix must be square to invert it.
ITERATIONS
solve(
has exceeded the maximum number of iterations
permitted. Examine a graph of the function. If the equation
has a solution, change the bounds and/or the initial guess.
