Help with a walk on an ellipse

[octohydra]

The problem is formally attached in the PDF. I did not see it fit to post my problem on the forum itself (sorry).

Any assistance is appreciated.

Thanks.

That is fine by me. I felt that this was the best way I could present the problem even if TeX is native to the forum.
