What is that ringed or double ringed integral?

I was told that it was a complex integral. So what's a complex integral?

Re: What is that ringed or double ringed integral?

Hi there!! I just wanted to write something not too foolish I hope..

A complex function is a function of complex number(s)

It can be assimple as  f(z) = z^2 which is the square of the complex number z

A contour integral is obtained when you integrate f(z) w.r.t  z
from one point on the complex plane ( the Argand diagram) to another point.

Usually when the path you follow starts from a point P & makes you travel along a path that brings u back again to the same point, this is probably the reason we use the french word Contour ( round about) integral... .                       {end of little comment.}
