Integrating WRT d^2 x or d^3 x

  1. Aug 6, 2009 #1
    Hi Guys,

    Ive gone through a 3 year physics degree but cant remember ever touching on this? Im doing some work and some of the theory contains integrals of d2x or d3R for instance. I have no idea how to do these.

    Any help?

    Thanks all

    They represent integrals over a surface or volume.

    Example:
    [tex]
    \int dV=\int d^3x
    [/tex]

    ...but rather nonstandard notation, so you should make sure your reader knows what you mean if you ever write it...

    Thanks guys, i thought it had something to do with that. Im still not sure how to evalute one when no symbols are given. Eg I have this function

    [tex]\int[/tex] e[tex]^{-abcd}[/tex] d3c

    and somehow they get

    (2pi)3/2[tex]\partial[/tex](bd)

    (sorry i suck at latex lol)

    where does the 2 pi come from WHAT IS GOING ON

    thanks all
