Many thanks, this Section is full of interest as usual, especially the development of three dimensional orbital theory resulting as usual in elegant results and graphics.

Subj: Section 3 of paper 361
In this section the expression for the acceleration in plane polar
coordinates was further simplified. I investigated the torkado example
as already mentioned. Besides the simplified discussion with plane polar
coordinates, I computed the full 3D dynamics in cylindrical coordinates.
Surprisingly the angular component of acceleration vanishes as it does
for the plane polar coordinate system for simple Lagrangian dynamics
