Integration has to do with a square shape

  1. Jan 5, 2006 #1
    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 [itex]\oint {}[/itex], which represents an integral over a closed path.

    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!
