I am having some trouble with these questions. Thank you in advance for your help

1:

Suppose that C is a triangle with vertices (0, 0), (4, 0) and (2, 2) oriented counterclockwise. Using Green's Theorem, find (xty) dx + 3xy dy.Let F(x,y) = Show that F is a conservative vector field. Find the potential function Use the Fundamental Theorem of Line Integrals to find F. dr where C is any path C from (2, It) to (4, 0 )
