HP 50g manual Function Solve

the figure to the left. After applying ISOL, the result is shown in the figure to the right:

The first argument in ISOL can be an expression, as shown above, or an equation. For example, in ALG mode, try:

NOTE: To type the equal sign (=) in an equation, use ‚Å (associated with the \key).

The same problem can be solved in RPN mode as illustrated below (figures show the RPN stack before and after the application of function ISOL):

Function SOLVE

Function SOLVE has the same syntax as function ISOL, except that SOLVE can also be used to solve a set of polynomial equations. The help-facility entry for function SOLVE, with the solution to equation X^4 – 1 = 3 , is shown next:
