Possible Causes and Suggested Remedies
You attempted to use a system variable inappropriately. See Appendix A.
• A singular matrix (determinant = 0) is not valid as the argument for
SinReg
• The instruction or a polynomial 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.
expression in the solve( function or the equation solver contains a singularity
(a point at which the function is not defined). Examine a graph of the function.
If the equation has a solution, change the bounds or the initial guess or both.
You attempted a stat calculation with lists that are not appropriate.
• Statistical analyses must have at least two data points.
Med-Med
• must have at least three points in each partition.
• When you use a frequency list, its elements must be
Xmax N Xmin à Xscl
• ( )
You attempted to display a graph when a stat plot that uses an undefined list is
turned on.
The command contains a syntax error. Look for misplaced functions,
arguments, parentheses, or commas. 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.
You requested a tolerance to which the algorithm cannot return an accurate
result.
You referenced a variable that is not currently defined. For example, you
referenced a stat variable when there is no current calculation because a list
has been edited, or you referenced a variable when the variable is not valid for
the current calculation, such as a after Med-Med.
