However, there is some debate as to his actual contribution the theorem.Figure 15.4.2: The circulation form of Green’s theorem relates a line integral over curve C to a double integral over region D. Notice that Green’s theorem can be used only for a two-dimensional vector field ⇀ F. If ⇀ F is a three-dimensional field, then Green’s theorem does not apply. Since.

Note that this does indeed describe the Fundamental Theorem of Calculus and the Fundamental Theorem of Line Integrals: to compute a single integral over an interval, we do a computation on the boundary (the endpoints) that involves one fewer integrations, namely, no integrations at all.
