    Description

=========== Cheatsheet for LaTex, using Markdown for markup. I use this with atom.io and :package:markdown-preview-plus to write math stuff. :package:keyboard-localization is necessary when using an international layout (like [swiss] german).

Further Reference and source: ftp://ftp.ams.org/pub/tex/doc/amsmath/short-math-guide.pdf

Example expressions / functions

Input	Rendered
$a = b + c − d$	$a = b + c − d$
$\sqrt{?\frac{\pi}{2}}$	$\sqrt{\frac{\pi}{2}}$
$y = a x_1^2 + b x_2 + c$	$y = a x_1^2 + b x_2 + c$

    基于 hugo katex mod 可以更有好的使用 katex 语法，下面给出了一个基本的用法：

\tag\*{(1)} P(E) = {n \choose k} p^k (1-p)^{n-k} \\
f(x) = \int\_{-\infty}^\infty\hat f(\xi)\,e^{2 \pi i \xi x}\,d\xi
