After the equation type is selected, [EQN] indicator lights up. The
following equation solve guiding page sample will be shown if you
specified the equation solve for two (2) or three (3) unknowns
simultaneous linear equation:
Coefficient name
a1?
(Sample display for simultaneous linear equation solve)
• For quadratic or cubic equation solve, the coefficient name starts
with "a"
• You cannot input complex number as an coefficient
• The calculation starts after the last factor ("c2": where the
simultaneous linear equations with two unknowns, "d3": where the
simultaneous linear equations with three unknowns, "c": quadratic
equation and "d": cubic equation) of the specified equation and
then the root of an equation appears.
