Document Summary

Math 180 solution to quiz #11b: cole. Let s be the surface {(x, y, z) : x2 + y2 + z3 z = 10, 2 z 1} with unit normal vector n pointing away from the z-axis. Solution: (a) g = 0 0, y(2z) ez, 2 z2 = 0, 2yz ez, 2 z2 . (b) the boundary curves occur when z = 1 and z = 2. When z = 1, we have the circle. When z = 2, we have the circle c2: x2+y2 = 10+8 2 = 16. (c) we use stokes" theorem. So, i = i1 + i2 where i1 = c1. We parameterize c1 with r(t) = a cos t, a sin t, 1 for 0 t 2 with a = 10. Since the direction is wrong, set c = 1. So, r (t) = a sin t, cos t, 0 and f(r(t)) = a sin t, 2 cos t, e cos t .
