Document Summary
S (x + eyz) ds, where s is given by r(u, v) =< u + v, uv, uv2 >, 1 u 2, 3 v 4: r r. S cos(xy2z) ds, where s is the part of the plane 2x + 3y + z = 12 in the rst octant: r r. S (x + 2y + 3z) ds, where s is the part of the surface z = x2 + y2 4 that lies below the (x, y) plane. x: r r. F ds, if f(x, y, z) = yi zj + xk, and s is the part of the graph z = xy, where x 0, y 0, x + y 1: r r. F ds, if f(x, y, z) = 2xi sin(yz)k, and s is the upper half of a unit sphere: evaluate r r.
