Use stokes' theorem to evaluate s ∫ f · ds. f(x, y, z) = x2 sin(z)i + y2j + xyk, s is the part of the paraboloid z = 4 − x2 − y2 that lies above the xy-plane, oriented upward.

Look at the image,

Step-by-step explanation:

This is an explanation of the same exercise but when the paraboloid is z = 9 − x2 − y2.  In that case you just have to replace 9 by 4 and follow the same steps :).

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.
