Abstract
This paper presents a new generalization of the standard homotopy analysis approach towards solving nonlinear oscillators equations with rational terms. By using this method, analytical approximations to the frequency of these oscillators and periodic
solutions are calculated. Excellent agreement of the approximate frequencies and periodic
solutions with exact ones is demonstrated and discussed. It is shown that this method is very simple, e ective and convenient for solving nonlinear oscillator problems with rational terms.
