Computer algebra-perturbation solution to a nonlinear wave equation
An asymptotic solution to the Cauchy problem of a nonlinear wave equation is found by using a perturbation method with MATHEMATICA. The comparison of the derived asymptotic solution and the numerical solution shows that they coincide for small values of the perturbation parameter \(\varepsilon\), and agree well for large \(\varepsilon\).
