How do you get epsilon to appear in comments? The only docs I could find on formatting are http://news.ycombinator.com/formatdoc and it has no clues.

Those familiar with LaTeX may find the following tool useful: http://www.unicodeit.net/ It takes LaTeX symbols as input and outputs the unicode for them. There is a mac app available too, which will convert it in-place for you too.

The solutions to

a⋅x² + b⋅x + c

are given by

x = (-b ± √(b² - 4⋅a⋅c)) / (2⋅a)

φ ∩ (ψ ∪ ρ) ↔ (φ ∩ ψ) ∪ (φ ∩ ρ)

Thanks! I can't even begin to describe how useful this will be!

If I could upvote this more than once, I would!

Unicode, of course: ε

When I need a Unicode character, I find it with my Unicode search page:

http://arachnoid.com/unicode

Then I copy the character into the document I'm working on. Others have more efficient ways to enter Unicode from their keyboards, like having a list of codes and a keyboard layout that allows the codes to be entered efficiently.

I just Google "unicode [name of character]". Hasn't let me down yet.

also, most platforms I have used have some kind of software to look up characters, e.g. on OSX you have something like "character map" where you can search by name/category
