I am having some trouble with this question. Thank you so much in advance for your help

Let F(x,y) =<3x2y4+exsin(y)eysin(x),4x3y3+excos(y)+eycos(x)>

1) Show that F is a conservative vector field

2) Find the potential function

3) Use the Fundamental Theorem of Line Integrals to findc F dr where C is any path from (0, /2) to (0, )
