文摘First, two tanh-coth type solutions of a class of nonlinear wave equation are derived by using a simplifiedmodified extended tanh-function method.Then, further analysis to some tanh-coth type solutions of nonlinear evolutionequations are given.The results show that when balance number m is one or two, the tanh-coth type solutions obtainedby the modified extended tanh-function method can be obtained by using the hyperbolic-function method.
