How do i find the potential function (phi) of a vector field? My example is:

F(x,y,z) = (2xy , x^2+z^2 , 2yz)

I have already used Poincare's lemma to show that this vector field is conservative (i.e. it is convex, and the partial derivatives are symmetrical) so how do i construct the potential function phi?
