The screen above right appears, indicating that there are 3
variables to be assigned.
Note:
If values were assigned to those variables prior to this operation,
then the previously set values will be shown here. For example, “C
= 57” may show up in this window; this simply indicates the value
of “C” was previously set to “57”.

to execute the SOLVER. The value of “C”
will be obtained.
* After the solution has been
found, press

to the variable input screen.
You may change the numeric
values for the variables and
