This needs a discussion regarding the alternate convention used by physicsts: rho and phi instead of r and theta.

The line element equation looks wrong. Shouldn't it be ds² = dr² + r²dθ² + dz² ?

--The line element is given in vector form; when you calculate the magnitude of it you indeed get the expression above.

I have adapted the notation to the standard ISO notation (ρ,φ,z). I think the article should be expanded to include the raltion with spherical coordinates, while the parts about cylindrical harmonics perhaps should go to an independent article. Gonfer (talk) 17:17, 2 February 2008 (UTC)

I agree with everything you mention above. PAR (talk) 23:05, 2 February 2008 (UTC)
