What's so special about calculating the arc length? Why is it so hard? What's the matter with ellipses?

What's so hard about? It's a simple integral

It's literally just the calculus version of the Pathogorean theorem. Why are you such a brainlet about this?

he didn't say he didn't understand it, he asked why is it so hard to compute it in general (and arc length IS hard to compute in general)

Define "hard". It depends on the underlying surface. Manifolds in general converge numerically making it a solved problem even when no symbolic solution is known.

there's nothing special about it, most integrals are a disaster to find closed forms for the moment you put a square root nested with other functions
