Many thanks, many things can be done now with the new Maxima code for solving simultaneous differential equations. Provided that the problem is defined precisely, the code can solve the equations no matter how complicated. The trajectories of the freely rotating symmetric top are theta(t), phi(t) and chi(t), and solutions can also be obtained for the freely rotating asymmetric top. Then, gravitational interaction between m and M is coded in, taking care to use the same frame of reference self consistently. This results in very complicated algebra, but complication is no problem. The Milankovich cycles should come out of this code. This could not have been done in the time of Euler and Lagrange because of the complexity. They could use intelligent approximations of course.

Subj: Re: New Results for 369(1)
Excellent, congratulations both. As you say, yet another first rigorous analysis.
