LaTeX Quick Dev Reference

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

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
