Regula Falsi method

A numerical method in evaluating a single root of a given function of x

It is a Bracketing numerical method in approximating a single root of a single function. It plots the given function to help the user select the appropriate lower and upper boundaries. It evaluates the lower and upper boundaries chosen by the user if it contains a root between them. It also lets the user choose between %relative error and number of iterations as the termination criterion.
