I need to find the surface integrals for these various questions. Some I don't know where to begin, others I don't know how to continue. Help would be appreciated

Not sure about this one

I get:

But not sure what the limits are to proceed

I'm guessing similar manner to question above, but do I get z on its own i.e.

then proceed. But once again, not sure what the limits would be

Using divF = 3 then

Is that right?

Need to use divergence again, but not sure how to proceed.

I could do the same as below, but not sure how to proceed

I got the curl to be

**i** +

**j** +

**k** and

Not sure how to proceed
