Abstract
Two nonlinear oscillators of relaxation type are studied for representing periodic orbits in terms of two inverse functions of x exp(x). The limit of the limit cycle of singularly perturbed van der Pol differential equation is approximated analytically; while the periodic orbit of singularly perturbed Lotka-Volterra system is represented in exact manner. These results are in an excellent agreement with numerical results computed via a stiff/nonstiff Maple ODE solver “NODES package” authored by Lawrence F. Shampine and Robert M. Corless. Some remarks are provided for the relaxation period.
