The van der Pol equation is u" + u - ε u'(1-u 2 ) = 0. (1) The analysis by multiple scales is sketched below, from "Problems in Perturbation," by A. H. Nayfeh, page 124. The solution to a shows the asymptotic approach to the steady-state amplitude of 2. Below, the expansion (13) is applied to (1) to get equations (14) and (15). The analysis procedes
