hi all

I'm eager to try more questions of the following sort:

"reparametrize the following by arc length:

$\displaystyle \gamma (t) = (t, cosh(t))$

if any of you can find any reparametrisation by arc-length questions in text books you may have lying around (or if you're extra special), if you could write some for me, i'd greatly appreciate it.

Thanks
