(4 points) Let F = 8(x + y) i + 6 sin(y) j. Find the line integral of F around the perimeter of the rectangle with corners (2, 0), (2, 2), (-1, 2), (-1, 0), traversed in that order. line integral = -16(4 points) Compute the flux of the vector field F = 5xi + 5y j through the surface S, which is the part of the surface z = 4 - (x + y ) above the disk of radius 2 centered at the origin, oriented upward. flux = 5y sqrt((4u^2+4v^2+1))
