LaTeX cheatsheet

This cheat sheet summarizes a reference list of LaTeX commonly used display math notation and some application examples of KaTeX.

#Getting Started

#Introduction

LaTeX A TEX-based typesetting system suitable for producing scientific, mathematical, and physical documents of high print quality.

LaTeX official website (latex-project.org)
KaTeX official website (katex.org)

And KaTeX handles only a smaller subset of LaTeX's mathematical notation for display on the web

#Example

 $% \f is defined as #1f(#2) using the macro f\relax(x) = \int_{-\infty}^\infty f\hat\xi\,e^{2 \pi i \xi x} \,d\xi$

% \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

#Inline

Based on KaTeX in one lineExample  
Example： `KaTeX:\int_0^\infty x^2 dx`

Example based on KaTeX showing on one line: KaTeX:\int_0^\infty x^2 dx
