Curl Theorem

A special case of Stokes' theorem in which F is a vector field and M is an oriented, compact embedded 2-manifold with boundary in R^3, and a generalization of Green's theorem from the plane into three-dimensional space. The curl theorem states

 int_S(del xF)·da=int_(partialS)F·ds,
(1)

where the left side is a surface integral and the right side is a line integral.

There are also alternate forms of the theorem. If

 F=cF,
(2)

then

 int_Sdaxdel F=int_CFds.
(3)

and if

 F=cxP,
(4)

then

 int_S(daxdel )xP=int_CdsxP.
(5)
