In this work, many new travelling wave solutions are established for the Boussinesq and the Klein-Gordon equations. The extended tanh method, the rational hyperbolic functions method, and the rational exponential functions method are used to generate these new solutions. The new solutions are bell-shaped solitons, periodic, and complex solutions. The proposed approaches are also applicable to a large variety of nonlinear evolution equations. (C) 2006 Elsevier B.V.
