Re: Maximising Arclength
Hi;
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

I solved it even before I posted here.
How does being 16 or being a moderator stop you from explaining like I am five?

Re: Maximising Arclength
Hmmm, you do not get to see the solutions. Over at the SE which is the best run forum I know they delete a question like that and bar the questioner.
