Let  the differential 2-form Ω = (3x2 + 2xy + 6y2)dx∧dy be defined in a star-like domain .  
(a) Is Ω closed?
(b) Is Ω exact on D? If so, find a differential 1-form Φ such that  Ω = dΦ.
◦ Ω is both closed and exact, Φ =   (xy2 + 2y3)dx + x3dy
◦ Ω is neither closed  nor exact
◦ Ω is both closed and exact, Φ =  - (xy2 + 2y3)dx + x3dy
◦ Ω is both closed and exact, Φ =  x3dx - (xy2 + 2y3)dy
◦ Ω is closed but not exact
