Ask Copilot2. Use the Green's theorem to evaluate the line integral along the given positively oriented curve. Sketch the curve.a.Ceydx2xeydy, where C is the qquare with sides. x=0x=1,y=0, and y=1.b.C(yex2)dx(2xcosy2)dy, Cis the boundary of the region enclosed by the parabola y=x2 and x=y2.c.cxydx2x2dy, C onsists of the line segment from (-2,0) to (2,0) and the top half of the circle x2y2=4.d.cy3dx-x3dy,C is the circle x2y2=4.
