Hi all,

I have question that goes as follows:

If is a scalar field, use stokes theorem to deduce that

Where C is a space curve bounding a closed space S.

When I look at the equations, I can see that , as by Stoke's theorem. However, I don't think that helps just yet. Apart from that, I'm not sure how to approach this question.

Any points in the right direction is greatly appreciated. Thanks in advance!
