Solve Calculations
The following is the syntax for using the Solve function in a program.
f x n a b
Solve( ( ), , , )
There are two different input methods that can be used for Solve calculations: direct
assignment and variable table input.
With the direct assignment method (the one described here), you assign values directly to
variables. This type of input is identical to that used with the Solve command used in the
PRGM mode.
