Simple Question on Equations

[catch.yossarian]

Just a simple question here:

Is there any application you guys use to make your equations you cut and paste into here, or is it something entirely different that you do?

[P.S. - I run Linux].

Edit: arildno beat me to it. :)

You can also click on anyone's equation in any forum and view a pop-up window showing what they typed to produce the equation. The best way to learn is by example.
