Theorem
Let C be a positively oriented, piecewise smooth, simple closed curve in the plane 2, and let D be the region bounded by C. If L and M are functions of (x, y) defined on an open region containing D and have continuous partial derivatives there, then
For positive orientation, an arrow pointing in the counterclockwise direction may be drawn in the small circle in the integral symbol.
In physics, Green's theorem is mostly used to solve two-dimensional flow integrals, stating that the sum of fluid outflows at any point inside a volume is equal to the total outflow summed about an enclosing area. In plane geometry, and in particular, area surveying, Green's theorem can be used to determine the area and centroid of plane figures solely by integrating over the perimeter.

“To insure the adoration of a theorem for any length of time, faith is not enough, a police force is needed as well.”
