Hi there. I have this simple conceptual question, I'm studing electrostatics, and the book speaks about azimuthal symmetry. The doubt I have is, whats the difference between azimuthal symmetry and cylindrical symmetry? I mean there is any difference between those symmetries? it looks like the same kind of symmetry to me, I can't distinguish between both, but as the books are refeered to azimuthal symmetry the thing bothers my a little bit. I'm not sure this is the right place for posting this, if its not, please just move it to the propper section. Bye, thanks for posting.
