On a further extended tanh method

Abstract In this Letter, we present a further extended tanh method for constructing exact solutions of nonlinear evolution and wave equations (NEWEs). By using this method via symbolic computation system Maple , we obtain abundant soliton-like and period-form solutions of the (3+1)-dimensional Jumbo–Miwa equation. Solitary wave solutions are merely a special case in one family. Our method can also be applied to other NEWEs.
