This paper shows how to solve some nonlinear wave equations as perturbation expansions in powers of a parameter that expresses the degree of nonlinearity. For the case of the Burgers equation u1+uux=uxx, the general nonlinear equation ut+u8ux=uxx is considered and expanded in powers of δ. The coefficients of the δ series to sixth order in powers of δ is determined and Padé summation is used to evaluate the perturbation series for large values of δ. The numerical results are accurate and the method is very general; it applies to other well-studied partial differential equations such as the Korteweg-de Vries equation, u1+uux=uxxx.
