In sundry fields of science and engineering, it is consequential to obtain exact or numerical simulation of the nonlinear partial differential equations. In science and engineering, to find the exact and numerical solution of nonlinear equations is still challenging, therefore it’s required lucid methods for finding the exact and approximate solutions. Sundry potent mathematical methods such as Adomian decomposition method (ADM), homotopy perturbation method (HPM) , homotopy analysis method (HAM) , variational iteration method (VIM) , Laplace decomposition method (LDM) , homotopy perturbation transform method (HPTM) , homotopy perturbation sumudu transform method (HPSTM) and homotopy analysis transform method (HATM) have been proposed to obtain exact and approximate analytical solutions of nonlinear equations.
