Analytical Approximate Solutions of the Systems of Non Linear Partial Differential Equations by Homotopy Perturbation Method (HPM), and Homotopy Analysis Method (HAM)

In this article two perturbation methods, namely Homotopy Perturbation Method and Homotopy Analysis Method are applied to the non linear partial differential equations, the results have been compared. The obtain results of HPM and HAM coincide with each other. Also the relations between these two methods are also explained.
