complex result. This error is not returned during
graphing. The TI-84 Plus allows for undefined values
on a graph.
You attempted to enter, or you have calculated, a
number that is beyond the range of the graphing
calculator. This error is not returned during
graphing. The TI-84 Plus allows for undefined values
on a graph.
You attempted to use a system variable
inappropriately. See Appendix A.
• A singular matrix (determinant = 0) is not valid
as the argument for L
• The
SinReg
regression generated a singular matrix
(determinant = 0) because it could not find a
solution, or a solution does not exist.
This error is not returned during graphing. The TI-84
Plus allows for undefined values on a graph.
