I can get most of this. I don't need you to do the problem for me (yet) but what I'm trying to figure out is r(t). Is it r(t)=(0,2cost,2sint)?

Well, if this ever gets answered I do need help. When I started I realized that the start is at (0,1,0) and is clockwise. But my answer was 0 which didn't seem right.

I ended up with:
$$-2[sint]_{0}^{2\pi}$$

Which gave me 0. Does this work out to be the case?
