The input of math, physics and computer science formulae has long been a chore. But now it is ... still a chore for those who don't know how to write formulae using the document markup language LaTeX. And simple for those who do.
Just enclose the formula you want to show up in a flashcard, note or comment by {$ ... $} and it will render neatly. For an overview of the most common used symbols see Wikipedia.
A few examples:
| This ... | Renders as ... |
|---|---|
{$ \omega $} |
 |
{$ 2 + 2 = 5 $} |
 |
{$ a^2 + b^2 = c^2 $} |
 |
{$ \frac{1}{x} $} |
 |
{$ \sum_{i=1}^{n} \left( \frac{1}{r} \right)^{\ell_i} \leq 1. $} |
 |
{$ \Omega = \sum_{p \in P} 2^{-|p|}. $} |
 |
{$ \left\lfloor \mathrm{mod}\left(\left\lfloor {y \over 17} \right\rfloor 2^{-17 \lfloor x \rfloor - \mathrm{mod}(\lfloor y\rfloor, 17)},2\right)\right\rfloor $}
