369(3): General Lagrangian Theory of the Earth’s Precessions and Nutations

The general theory is very intricate, but can be solved by solving Eqs. (6) to (8) and (19) simultaneously to give the trajectories r(t), theta(t), phi(t) and chi(t). These trajectories are related to the Milankowich cycles, so this kind of theory could predict the climate changes due to the Earth’s precessions and nutations in the gravitational fields of the sun, moon and planets. It is clear from inspection that the Milankowich cycles are very intricate, as is well known. This may be the first complete solution of the problem.
