Evaluate the integral dy Adz +2dz Adr+ 3dr A dy where S is the oriented planar triangle with vertices (2,2,2), (6, 10,-2), (8,4,2) in that order. Evaluate the integral 2 rydr Ady + rydy Adz where S is the region in xy-plane, with anti-clockwise orientation, bounded by the curves y = r, y=2-2, r=0 and r = 1.
