A $\LaTeX$ cheat sheet inspired by Karl Ventayen .

For now, this site focuses on statistics notation, because that's where this idea first came from.

Search for some math, $\LaTeX$, or other key terms. $\LaTeX$ code for the math symbols show up in this color and style . Most of this syntax should be portable across various $\LaTeX$ implementations. This site uses $\KaTeX$ and assumes you know enough already to surround all the latex code in dollar signs, like $\alpha$ to get $\alpha$. And use double dollar signs to get display mode math, that is centered and generally taller math expressions.
