Evaluate the line integral using Green's Theorem and check the answer by evaluating it directly. O 2 ydx + 4 x²dy, where C is the square with vertices (0, 0), (3, 0), (3, 3), and (0, 3) oriented counterclockwise. + 4x*dy = i

3) Compute the curl of F= (4 xy) i + (2x² + 2z²) j + (4 yz) k.

// (curl F) •n dA directly for F= [z², –x²,0], S : the rectangle with vertices (0,0,0), (4, 0, 0), (0, 4, 4), (4, 4, 4). NOTE: Enter the exact answer. / (curl F) •n dA=± 0
