Exact and Numerical Solution of Lienard's Equation

Abstract

In this paper, exact and numerical solutions are obtained for the Lienard\u2019s equation by variational homotopy perturbation method (VHPM). Comparisons are made among the variational iteration method (VIM), the exact solutions and the proposed method. The results reveal that the proposed method is very effective and simple and can be applied for other nonlinear problems in mathematical.
