Here's the question you clicked on:

vector field: F(x,y,z) = (cosxsiny -sinxcosz, sinxcosy -sinzsiny, cosycosz-sinzcosx +1). How do I find the line integral of F using the potential? (Potential was previously worked out: ϕ(x,y,z) = -sinxsiny+cosxcosz-cosysinz)
I think you start by finding the gradient vector first of f on a given range. I think.
What did I just read....? @Hero @TuringTest @amistre64 @UnkleRhaukus
I'm not sure what is meant by "line integral using the potential". On what line are you integrating?
Hm, watch this: http://www.youtube.com/watch?v=zq9Ljkz_Yng Summarily, I am trying to calculate the work done by a vector field, and this is found out by working out the line integral (apparently this is Calculus III)
since it is conservative, it would be f(r(b)) - f(r(a)) refer to fundamental theorem for line integrals
Thanks, I've got it now. :)
