(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

http://www.geocities.com/asdfasdf23135/advcal26.JPG

Note:

path-connected means arcwise-connected

C^0 means continuous

⊿f=Laplacian=(f)xx+(f)yy

df/dn = grad f ． n

2. Relevant material

Green's theorem, line integrals, ...

3. The attempt at a solution

The only part I can finish is part (ii):

(ii) follows from the vector version of Green's theorem by letting F=grad f

How can I do parts (i) and (iii)?

And provided that I have proved (i), (ii), and (iii), how would these results aid me in proving the actual problem?

Any help or hints would be greatly appreciated!https://www.physicsforums.com/images/smilies/smile.gif [Broken]
