One very useful feature of the calculator is its ability to store and recall equations.
The solution from various values for known variables can be easily obtained by
recalling an equation which has been stored and giving values to the known
variables in the Solver mode. If a starting point is known, Newton's method is
useful for quick solution of a complicated equation.
