Q2 (10 points) use the green-stokes formula in order to compute the vector line integral: (z + y') dx + (2x - z) dy + (x- - y) dz where t is the triangle with vertices (1, 0, 0), (0, 1,0) and (0, 0, 2) traversed in the direction implied by the order in which the vertices were given (i. e. from the 1st to the 2nd, to the 3rd and then back to the 1st one).
