 regarding problem p.132, #9; there is no field whose curl equals xi
If we assume there was such a field, say F, then we would have
curl F = x i
but then, taking the divergence of both sides we find:
div curl F = 0 (identity 3.41)
while
div(x i) = 1
so this is impossible.

Thanks for letting me know; I will try to scan the homework and post it
(hopefully by Monday). Meanwhile see if you can find somebody else taking
the class; alternatively, you are welcome to come by my office Monday 
(I'll try to either be in my office or leave a copy of the book at the
front desk for you to copy a few pages off). I'll make sure it is there   
for you by noon.
