Integrating a norm

  1. Nov 15, 2009 #1
    [tex]\int[/tex]|x|2 with respect to the vector x in the unit ball in Rn-2

    I'm dealing with volumes of unit balls in Rn and after applying a change of variable to the last 2 components and Fubini's Theorem, I get that integral and can't find a way to integrate it. Any help on this?

    Generalized spherical coordinates.

    Would that just make |x|2=r2? I've never worked with generalized spherical coordinates before, so could you elaborate a bit?

    Nevermind, I found an alternate way.
