Hi,
to get acquainted with LaTeX, you may want to look at the following:
http://www.sitmo.com/latex/

It's an online equation editor where you can enter maths either via a
question (\oint) is right there.
The output is a bitmap image of your equation, which is a really neat
service, e.g., for putting maths into emails etc.

In Firefox, this is especially nice when you combine it with Google's
presentation software. If the two are running in separate windows
side by side, you can _drag_ the equation image
directly from the editor into the presentation.
