Abstract:In this paper four new Jacobian elliptic functions are created by applying methods of projection Riceati equation and Jacobian elliptic functions expansion, which generalize the second method. Moreover, the exact periodic solutions to nonlinear Klein - Gordon equations are given by means of symbolic computation system Mathematiea. In particular, the solutions will degenerate to solitary wave solutions and triangle function solutions when the modulus of the Jacobian elliptic function m approaches to 1 or 0.
