NettetIt's an integral over a closed line (e.g. a circle), see line integral. In particular, it is used in complex analysis for contour integrals (i.e closed lines on a complex plane), see e.g. example pointed out by Lubos. Also, it is used in real space, e.g. in electromagnetism, … The integral symbol: ∫ (Unicode), (LaTeX) is used to denote integrals and antiderivatives in mathematics, especially in calculus.

"NettetSo if you integrate over C and C is the circumference of the circle, then the limits of integration should be 2*pi*r, where r is the radius of the circle in meters. So in this case it is 1 meter to make it simple, so r =1 meter. And the force opposing the movement of the particle is in N, so you get 2 pi Nm. " - Integral sign with a circle
