Here is the first one.
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,
I got the answer : 18.684. 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 ?
3) and finding the curl function f
.
All I know is, it has something to do with curl. Something like F = grad f.
Thanks again !
