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

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.
