A dynamical system is, in its most general form, described by a system of six coupled first order differential equations which cannot be solved rigorously. An approximate solution is nevertheless possible and fruitful using a perturbation method which can be decomposed in two steps: the conversion of the original system into sub-systems characteristic of the order at which the perturbation is treated, then the recursive integration of the various sub-systems. The method of time-dependent perturbations has been adopted.
