Description
Circulation of a vector field F along a closed curve C is measured with a line integral.
where t̂ is the unit tangent vector. See here for an explanation of dr.
When the vector field is given as F = <P(x,y), Q(x,y)>, Green's theorem gives a method for evaluating this.
This can also be easily reformulated into a vector form that uses curl.
