ABSTRACT

In this paper, with the aids of the symbolic mathematical software-Maple, we obtained traveling wave solutions of symmetric regularized long wave equation. These traveling wave solutions include solitary wave solutions and trigonometric functions periodic solution. Some typical waveforms of these traveling wave solutions are obtained by Maple software. Obviously, the method which has been used in this paper is also can be used to other nonlinear evolution equations.
