Hello! I'm new to this forum so bear with me as I figure latex out. I have a calc 3 test on Wednesday so be expecting a lot of questions from me :-)

My question is how do I find the arc length parametrization with the same orientation for ?

t>= 0, t=0 is the reference point.

I got to but can't figure out how to integrate. Is there some calc 2 trick I'm forgetting?

Thanks in advance!
