I was wondering, how you break down dS to something with dA? I know that dS is equal to ndS. The n is equal to grad f / (magnitude of grad f) and the dS is equal to the same as the magnitude of grad f right? So is the formula the same as double integral of region D (curl F * grad f) dA?

Thanks a lot for your help, I think i understand a bit better now.

Thanks, for example, on this problem: http://i32.photobucket.com/albums/d9/XXHoR0HoR0XX/physicsquestiontwo.jpg?t=1298243404 and the solution is this: http://www.cramster.com/solution/solution/858898 how would I know that the angle is 96.9 degrees?

Oh, I actually got in now, I was using the wrong angles for them... I was just wondering if you could also clarify how to find the angles when using the parallelogram law or triangle rule.. I'm still a bit unclear about that. When I add the vectors together, I can't figure out how to find the...
