| Abstract: | In this paper the three variables iteration method is suggested to find the periodic solutions and determine their stability of fully strong nonlinear autonomous systems of 2nd order. The comparison between the results obtained by our method and those obtained by numerical method shows that the three variables iteration method is both effective and of high accuracy. |
