Let C be the curve of intersection of the plane z | z - 6 and the cylinder + + y' = 9. a) Draw a surface whose boundary is the curve C. b) Use Stoke's Theorem to set up the alternative integral to F . dr C where F(r. y. 2) = (ry. 32. 7y) and C' is the curve of intersection of the plane r + = = 6 and the cylinder a + 1 = 9 oriented clockwise as viewed from above.
