Gradient in hyperspherical coordinates

  1. Mar 24, 2009 #1
    Does anybody know, or know where to find, the expressions for the gradient and/or divergence in hyperspherical coordinates.
    Specifically, I'd like to know [tex]\nabla \cdot \hat{r}[/tex] in dimensions higher than 3.

    Nevermind, it's (D-1)/r.
