1. The problem statement, all variables and given/known data 2. Relevant equations I'm guessing Stoke's Theorem? However, I'm not sure how to apply it exactly.. 3. The attempt at a solution Looking at Stoke's Theorem, I'm still not sure how to apply it. I'm really just lost as to where to begin; is there even a [itex]\grad F[/itex] to take? I know this is related to Stoke's (I hope), but not sure how to begin.
