URGENT !!! need help with these 3 integrals problems Hi, I need urgent help with these 3 integrals problems ... been stuck on the questions and the deadline is Friday. Thanks a lot ! 1) For the green's theorem, >> see attach I got the answer : 27.552. Not sure whether it is correct. Please kindly explain in steps so I know where I went wrong. 2) I'm totally unsure about finding the surface integral. How do I know the shape of the surface ? >> see attach 3) and finding the curl function f >> see attach All I know is, it has something to do with curl. Something like F = grad f. How do I find the function ? Thanks again !
