I formulated the divergence first. For the divergence: [tex]\nabla . (r^n\hat r) = (n+2)r^{n-1}[/tex] and the functon becomes a dirac delta at the origin in case of

**n = -2**.

For the curl:

Geometrically, the curl should be

__zero__. Likewise, the curl in spherical coordinates obviously gives

__zero__.

My question is how can one be certain that there is no Dirac Delta function lurking here(for the curl)? (My understanding of Dirac delta function is a bit poor, so additional explanations would help .)
