Comparison between the (G′/G)-expansion method and the modified extended TanH method and improving unified method

The aim of this study is to introduce and compare the family of the tanh-methods and the family of the -expansion methods which is widely used to solve nonlineer partial differential equations over 20 years. Giving detailed information with regard to these two methods and applications in section 2, two members of these two families frequently used compared and determined similarities and differences of two methods in section 3. Afterwards, in section 4, these two families are unified in one method which is called unified method. Maple was used throughout the study for algebraic operations.
