New Exact Solutions of Some Nonlinear Partial Differential Equations via the Hyperbolic-sine Function Method

In this paper, we establish exact solutions for some nonlinear partial differential equations. The hyperbolic-sine method [16] is used to construct periodic and solitary wave solutions for some soliton equations and systems such as the generalized Klien-Gordon, the general improved Kadomtsev-Petviashvili (KP), and the Zakharov-Kuznetsov (ZK) with power law nonlinearity equations, the generalized coupled Drinfeld –sokolov – wilso, and the generalized coupled Hirota-Satsuma Kdv systems.
