Extended improved tanh-function method for solving the nonlinear physical problems. (English) Zbl 1165.35046
Summary: By means of the extended improved tanh-function (EITF) method with computerized symbolic computations for constructing new multiple traveling wave solutions for different kinds of nonlinear physical problems are presented and implemented. The solutions for the nonlinear equations such as coupled MKdV, coupled Hirota-Satsuma and coupled KdV equations which include new trigonometric function solutions and rational solutions are exactly obtained.
