Fifth and sixth-order iterative algorithms without derivatives for solving non-linear equations Article uri icon

abstract

  • In this paper we will present two derivative free iterative methods for finding the root of a nonlinear equation f(x) = 0. The new methods are based on direct and inverse polynomial interpolation. We will prove that one of the methods has fifth-order convergence and the other method sixth-order convergence. Several examples will show that convergence and the efficiency of the new methods to be better than the classic Newton%27s method and others derivative free methods with high order of convergence previously presented. © 2013 Academic Publications, Ltd.
