If the series for the perturbation term Ω contains a term of the form cos  (v) ,integration yields terms such as v sin (v)  which represent unbounded behaviour of the orbit. Clairaut adjusts the expansion to eliminate this effect. Firstly in this process, there is the technique of integrating while keeping slowly varying quantities such as c fixed and secondly there is a procedure to avoid secular terms which is related to the modern approach.  Lagrange and Laplace developed and used this technique of obtaining approximate. The treatment in Laplace’s Trait´e de M´ecanique C´eleste [1] is very technical. In Laplace’s study of the Sun–Jupiter–Saturn configuration one can find the ingredients of the method of averaging and also higher-order perturbation.  Lagrange, after discussing the formulation of motion in dynamics, argues that to analyze the influence of perturbations one has to use a method which we now call ‘variation of parameters’. Lagrange starts by transforming the problem to the standard form
