• Variables and numerical values stored in the
memories will be displayed in the variable entry
screen. If you do not want to change any values,
simply press e .
• Performing simulation calculation will cause values
in memory to be overwritten with new values.

Solver Function
The solver function fi nds the value for
the entered expression to zero.
• This function uses Newton's method to obtain an
approximation. Depending on the function (e.g.
periodic) or start value, an error may occur (ERROR
02) due to there being no convergence to the solution
for the equation.
• The value obtained by this function may include
a margin of error. If it is larger than acceptable,
recalculate the solution after changing the "Start" and
x
d
values.
• Change the "Start" value (e.g. to a negative value) or
x
d
value (e.g. to a smaller value) if:
• no solution can be found (ERROR 02).
• more than two solutions appear to be possible (e.g.
a cubic equation).
• to improve arithmetic precision.
• The calculation result is automatically stored in the X
memory.
• Press j to exit the solver function.
