Hi I have mentioned yesterday some integrals that have a circle in the symbol... I think the integration has to do with a square shape... What is this? Where i can find more info?

Also do u know what anadelta means?

I suppose you mean something like $\oint {}$, which represents an integral over a closed path.

Thx a lot if we want to calculate the area of a square.. Lets assume that the square has the following 4 point a b c and d.. How should i use the integral?
Thx a lot

I don't think you'd be using a (closed) path integral for that purpose.

You could use Green's theorem to convert the double integral one would normally used to find area into a path integral but that's the hard way!
