LaTeX 备忘清单
本备忘单总结了 LaTeX 常用显示数学符号的参考列表和一些 KaTeX 的应用示例。
入门
介绍
LaTeX 基于 TEX 的排版系统，适用于生成高印刷质量的科技和数学、物理文档。
而 KaTeX 只处理 LaTeX 的数学符号的一个更小的子集，用于 web 上展示
示例
% \f is defined as #1f(#2) using the macro
f\relax(x) = \int_{-\infty}^\infty
f\hat\xi\,e^{2 \pi i \xi x}
\,d\xi
% \f is defined as #1f(#2) using the macro
f\relax(x) = \int_{-\infty}^\infty
f\hat\xi\,e^{2 \pi i \xi x}
\,d\xi
行内展示
基于 KaTeX 在一行
展示示例： `KaTeX:\int_0^\infty x^2 dx`
基于 KaTeX 在一行展示示例： KaTeX:\int_0^\infty x^2 dx
