New homotopy perturbation method for solving nonlinear differential equations and fisher type equation

In this paper, we apply the new Homotopy Perturbation Method (NHPM) to get accurate results for solving systems of nonlinear equations, we indicate that our method (NHPM) is equivalent to the Variational Iteration Method (VIM) with a specific convex. Four examples are given to depict our proposed methods. The method is easy to carry out and gives very accurate solutions for solving linear and nonlinear equations.
