Abstract
We discuss an iterative method to solve a nonlinear equation, which is free from
derivatives by approximating a derivative in the two-step Newton method by the
method of undetermined coefficients and forward difference. We show analytically
that the method is of three orde for a simple root. Numerical experiments show that
the new method is comparable with other discussed methods.
