I'm interested in writing a formula sheet for an upcoming exam in Physics. I want to create something similar to this. I have the sources, however, I can't understand what's going on over there, and I can't seem to render it using LyX. I have used LyX for quite a while and used some ERT (TeX code) now and again, but I am by no means a LaTeX expert. I have no problem writing some LaTeX code if needed (and I'm pretty sure it'll be needed), but if you suggest it, please explain the code. Also, I do want the main editing of formulas, etc. to be done in LyX.
Any suggestions?
You could build something similar to that with the web app at http://www.formulasheet.com, which uses Latex to create formulas, without having to worry about the Latex source for page placement.
