It is shown that this technique is equally effective in treating nonlinear parabolic partical differential equations. The derivation of these methods is purely based on variational iteration technique. The name "Newton's method" is derived from Isaac Newton's description of a special case of the method in De analysi per aequationes numero terminorum infinitas (written in 1669, published in 1711 by William Jones) and in De metodis fluxionum et serierum infinitarum (written in 1671, translated and published as Method of Fluxions in 1736 by John Colson). An iterative procedure for solving the system based on the Generalized Newton-Raphson (GNR) method is described and compared to other methods currently being used to solve such problems.
