root integral
Hi. In one of my homework problems, I have to find the arclength of
If y' = x^(1/3), then I believe that translates into
(Not sure how to add the bounds with TEX formatting.)
But I'm not sure what to do with that integral, as usubstitution doesn't seem to apply. Could someone point me in the right direction?

Black magic if I ever saw it! Thanks!
BTW, what is the TEX syntax for adding bounds to your integrals? The tutorial says integrals are \int{...}, but that is all I know.

You do \int_0^1f(x)\,dx to get . The "\," just adds a little space  without it, it looks like .
If you mouse over the graphical formula, it gives you the source text. It also usually works to copy the graphical formula and paste it into an input box  it gives you the source text.
