Dear Ary,
Your question is a bit difficult to interpret. Sin[x y] has maxmin = {-1,1}
for x and y reals.
However, I believe this example my help you out. It will find "some" of the
maxima, but not all.
FindMaximum[(1 + Sin[x y])/(2 + Cos[y]), {{x, 1}, {y, 2}}]
Here x and y will be real numbers.
To find all max/min--inima, you could take derivatives symbolically and
Solve symbolically
Cheers, Craig
