Integral Notation Question

  1. Mar 9, 2010 #1
    I saw this notation in a textbook but I'm a bit confused by it. What exactly does the 3 mean? Is it shorthand for a triple integral in spherical coordinates?

    [tex]\int{d^3 r}[/tex]

    Thanks in advance.

    It means a triple integral, not necessarily in any particular coordinate system.
