Harry Lass; R. M. Georgevic

yields an integral for the period of a periodic solution, if such exists. In general, this integral cannot be evaluated. By means of an approximate solution along with the minimization of a mean-square error, one can obtain an approximate value for the period in terms of the amplitude of the motion. The calculated period agrees very well with the period obtained by means of numerical integration for the case of orbit-orbit resonance involving the motion of two satellites of a planet.The same method is applied to obtain an alternative derivation of the first Krylov-Bogoliuboff averaging method in non-linear mechanics.
