| Abstract: | Using direct integration method generalized KDV-MKDV equation was converted the equation into a first-order nonlinear ordinary differential equation,then some new exact solutions were got using undetermined coefficient method,the exact solutiobns were also got using the method that,the assumption transformation was firstly done,then trial function was selected.The result by making the assumption that the use of trial function. |
