Why can I only use some capital greek letters inside my equations?

Refering to http://wikieducator.org/Help:LaTeX_Symbol_Tables_-_Mathematics, I am trying to enter upper case Zeta into my tex file. When I enter $\zeta$ it compiles the code but when I say $\Zeta$ with upper case Z with a expectation that it would lead to upper case zeta, it does not compile. Am I missing something?

I am using Kile (Version 2.0.85) under Ubuntu (Version 11.04) and using Latex to compile the code. All other symbols like Uppercase Omega are not causing any problem.

Answer 1

The uppercase Zeta is Z, so simply write Z. You may define \Zeta yourself, such as

\newcommand{\Zeta}{Z}

or

\newcommand{\Zeta}{\mathrm{Z}}

depending on your needs.
