About Green's Theorem

Statement

Green's theorem relates a line integral around a simple closed curve C to a double integral over the plane region D bounded by C. It's a special case of Stokes' theorem.

Conditions

  • C must be a simple, closed curve
  • C must be traversed counterclockwise
  • P and Q must have continuous partials
  • D must be simply connected
