- Revisiting the elliptical loop-the-loop problem using the more formal approach of Lagrangian mechanics. The geometry of the problem suggests that elliptic coordinates are the most natural choice, which makes this is a good example of working in a non-standard coordinate system!

Standing Ovation!🙌 What a beautiful solution!
Thanks! It was satisfying to reach the same result as with the radius of curvature method after all that working.
Simply brilliant, indeed !
Thank you!
My goodness what a problem! Thanks for showing this example. Nonstandard coordinates are rarely encountered in university courses problems.
Indeed, I don't think I had ever worked in this coordinate system until a few weeks ago when it occurred to me to try solving this!
Never thought about this before. Really goes beyond the standard sqrt(5gl) result in string pendulums 😅
Very well explained! Thank you
Lagrange would be proud!
Ha, I hope so!
