solve

public double solve(FunctionI function,
                    double x1,
                    double x2,
                    double y)
             throws NonlinearException,
                    AccuracyException

Find x between x1 and x2 where f(x) = y.

Specified by:

solve in interface EquationSolutionI

Throws:

AccuracyException - if the answer isn't found to the specified accuracy.

NonlinearException - if f(x1) and f(x2) don't bracket y.
