Divergence in cylindrical coordinate system

  1. Oct 14, 2007 #1
    I am trying to understand the derivation of the divergence formula in cylindrical coordinates. www.csupomona.edu/~ajm/materials/delcyl.pdf [Broken] paper does a good job of explaining it but I don't understand 2 things that the author does.
    [tex]\frac{\partial\hat{\rho}}{\partial\phi} = \hat{\phi}[/tex] and [tex]\frac{\partial\hat{\phi}}{\partial\phi} = \hat{\rho}[/tex]
    Derivation is on page 3.
    Can anyone help me understand this?

    go back to page 1: "derivation of unit vectors with the coordinates"
