Statistical Calculations (Sd, Reg) - Casio fx-100MS User Manual

To solve
Important:
(solution variable), SOLVE may not be able to obtain solutions. If
this happens, try changing the initial value so they are closer to the
solution. • SOLVE may not be able to determine the correct solution,
even when one exists. • SOLVE uses Newton's Law, so even if there
are multiple solutions, only one of them will be returned. • Due to
limitations in Newton's Law, solutions tend to be difficult to obtain for
equations like the following:
expression does not include an equals sign (=), SOLVE produces a
solution for expression = 0.
