In this paper, we obtain the analytical solutions of nonlinear partial differential equation using G /G -expansion method. The solutions obtained here are expressed in hyperbolic functions. The general and special solutions can be obtained Using G /G -expansion method. This method is very effective to obtain exact solutions of nonlinear partial differential equations.
