Calculating Electric Field E^pho in Cylindrical Coordinates

[MidnightR]

How would I go about working out the Electric Field E(X) in cylindrical coordinates? The question is,

Suppose pho = pho(r) find E^pho. Suggestion to use Greens & Gauss theorem

so you already have the field in cartesian coords?

use your words midnight, you can do it...

what ideas do you have?

Suppose pho = pho(r) find E^pho.m

by the way what do you mean by this?

This is my biggest problem, trying to figure out what the hell my lecturer means :S I mean I assume he wants us to find it in cylindrical coords by the diagram & reference to r^2 = x^2 + y^2...
