As an example, consider f(x,y)=xy2, and let F(x,y)=∇f(x,y)=(y2,2xy). Since we wrote F as a gradient, we know that F must be conservative.

The gradient theorem, also known as the fundamental theorem of calculus for line integrals, says that a line integral through a gradient field can be evaluated Proof · Examples · Example 3 · Converse of the gradient...
