Elliptic path, normal and tangential acceleration

@ehild Still no canceling out... I really don't see it. :/ (I wrote only the top line in the attached file because it's so long)

You forgot to square sin and cos in v^2

@JulienB
##(\vec v)^2=w^2(a^2\sin^2(wt)+b^2\cos^2(wt))##
##(\vec a)^2=w^4(a^2\cos^2(wt)+b^2\sin^2(wt))##
What is their product?

@ehild aaaah it worked out now! I get the same result as with the other method! Thanks a lot, that was crazy! ;)

Well done. I must sleep now but tomorrow I show you how the formula you used is connected to vector products.

@ehild Thanks a lot! I must sleep too otherwise I would post the correct calculation again. I'll do it tomorrow.
