KELUARGA BARU METODE ITERASI ORDE DELAPAN OPTIMAL UNTUK MENYELESAIKAN PERSAMAAN NONLINEAR

Abstract

This article discusses a new family of three-step iteration method. Analytically, it is showed using Taylor expansion and geometry series that this iterative method has a convergence eight-order. Numerical comparisons show that this method is comparable with the others eight-order methods and can be used as an alternative method in solving nonlinear equations.
