TEKNIK ITERASI VARIASIONAL DAN BERBAGAI METODE UNTUK PENDEKATAN SOLUSI PERSAMAAN NONLINEAR

Abstract

This article discusses a new iterative method based on the variational iteration technique, which is free from second derivative. This method has two-step in which the rst-step is Newton's method. In the discussion three speci c cases by choosing certain free functions in a general form of the variational iteration technique are mentioned. Analytically it is shown that the general form of the method is of order three. To see the performance of the method, the comparison with two known methods is also given.
