New Approach of Generalized $exp ( -phi ( xi ) ) $ Expansion Method And Its Application to Som Nonlinear Partial Differential Equations

摘要

In this article, the new approach of generalized $expleft(-phileft(xiight)ight)$ expansion method has been successfully implemented to seek traveling wave solutions of the Korteweg-de vries equation and the modified Zakharov-Kuznetsov equation.?The result reveals that the method together with the new ordinary differential equation is a very influential and effective tool for solving nonlinear partial differential equations in mathematical physics and engineering.The obtained solutions have been articulated by the hyperbolic functions, trigonometric functions and rational functions with arbitrary constants.
