The tanh method: A tool for solving some mathematical models

The tanh (or hyperbolic tangent) method was used to find travelling wave solutions for a model that combines Schrödinger and two types of Korteweg–de Vries equations (a coupled set of (1+1) dimensional). Various travelling wave solutions were obtained, the validity of these solutions was tested numerically by a mean of residual. Finally, some numerical results were given.
