I need yr help in Green theorem, please please please

Dear Frends and Teachers,

This is Issam, I'm really need your help to solve anyone of the following 2 questions as shown in attached files, it's about Green theorem on Abstract Algebra

I'm really in critical time and I hope to get any idea to solve them or help me to solve anyone

I'm looking forward to get yr help ASAP

You know Green's Theorem, correct? Start with the second problem.
If you have a function $g(x,y)$, how do you write $dg$? I'm not going to give any more info right now. Try that, take a look and ask more questions if it isn't clear (also, this should be in calc, not intro phys).

Both of your problems are pretty standard identities and uses for EM waves. You could probably find proofs of those in an advanced electrodynamics or optics book. Before we can really help you, we have to know where you're stuck, so try out the problem somewhat.
