Use Stokes' theorem to evaluate the integrals given in Exercises 1 through 4. In each case, determine the direction in which we need to traverse C in order to obtain a positive value. %(y2 22)da: + (22 3:2)dy + (3:2 y2)dz, C Where C is formed by the intersection of a: + 2y + 32 = 4 with the planes 3: = 3, y = 2, and z = 1, respectively. Hint: C is the boundary of a triangle. Find a pullback from this triangle to the fundamental triangle in u, 1) space
