New exact solutions of some non-linear evolution equations via functional variable method

Recently, many successful methods have been developed to achieve analytical solutions of nonlinear partial differential equations. In this study, some new exact the non-linear coupled Klein- Gordon system and modified Benjamin-Bona-Mahony equation obtained by using functional variable method (FVM). Additionally, all examined three dimensional graphics drawn Mathematica program. These equations used in various fields such as plasma physics, biophysics, fluid dynamics. The main advantage FVM is generate more than other therefore, an effective powerful solve evolution engineering mathematical physics.
