What library do I have to use such that the document can render \lt and \gt as less than and greater than signs, respectively?

Question

\documentclass{article}
%\usepackage{amsmath} It does Not work !
\begin{document}
\[
x\lt y \gt z
\]
\end{document}

What library do I have to use such that the document can render \lt and \gt as less than and greater than signs, respectively?

Edit

I am using MathJax library in my site under Asp.net Mvc 3. Web application is vulnerable to XSS and XSRF attacks so < and > should be avoided as the input from the users.

My database will save LaTeX commands that can be rendered by both LaTeX compiler and MathJax. Therefore, I need \gt and \lt that already work in MathJax.

In general have a look at “How to look up a math symbol?” for ideas how you can easily find a particular symbol. — Martin Scharrer, Mar 03 '11 at 07:19

So you are using LaTeX on a webserver with user input or what? You should mention such things in the question. — Martin Scharrer, Mar 03 '11 at 07:22

If that's all you want, add

\newcommand{\lt}{<}
\newcommand{\gt}{>}

to the preamble (before begin{document}). This should allow you to use \ltand \gt.

+1, and if you don't want this in the main document put it into your own .sty file and load that using \usepackage. – Martin Scharrer Mar 03 '11 at 07:26
