Is this what you were asking about?

< f(x) | g(x) >

$\langle f(x)\mid g(x)\rangle \,$

One other thing that I might as well tell you about up front, to save you some frustration: When you use the TeX markup facilities (simplest way is to click on the ${\sqrt {n}}$ icon along the top) the result sometimes doesn't show as actual TeX stuff. The wiki software tries to figure out how to display without actually going to TeX, and, for simple equations, it sometime succeeds. So, at the end of your equation, put in a "\," (backslash, comma), just before the </math>. That forces an extremely narrow space, that can't be displayed without using TeX.

More generally use help:formula as your guide when doing equations. William Ackerman 22:42, 6 November 2006 (UTC)
