Abstract:

We used the first integral method to solve a class of nonlinear wave equations and obtained the exact form of traveling wave solutions. Furthermore, the validity and efficiency of this method were shown by numerical calculation of nonlinear wave equation, indicating that it can be applied to other hyperbolic evolution equations.

Key words: first integral method, nonlinear wave equation, traveling wave solutions
