LaTeX 語法整理

前言

使用 LaTeX 這款排版工具也有 1 年多了，有鑑於在查語法時常重複查詢造成效率下降，加上朋友的建議，於是就來整理份常用的 LaTeX 語法吧！

基本

程式碼LaTeX程式碼LaTeX
a_1\(a_1\)x^{2018}\(x^{2018}\)
e^{-\alpha t}\(e^{-\alpha t}\)a^3_{ij}\(a^3_{ij}\)
e^{x^2} \ne {e^x}^2\(e^{x^2} \ne {e^x}^2\)94 \times 87 = 8178\(94 \times 87 = 8178\)

根號

程式碼LaTeX程式碼LaTeX
\sqrt x\(\sqrt x\)\sqrt{x^2 + \sqrt y}\(\sqrt{x^2 + \sqrt y}\)
\sqrt[3]{2}\(\sqrt[3]{2}\)\surd[x^2 + y^2]\(\surd[x^2 + y^2]\)

線、向量

程式碼LaTeX程式碼LaTeX
\overline{m + n}\(\overline{m + n}\)\underline{m + n}\(\underline{m + n}\)
\vec a\(\vec a\)\overrightarrow{AB}\(\overrightarrow{AB}\)

其它

程式碼LaTeX程式碼LaTeX
\underbrace{a + b + \cdots + z}_{26}\(\underbrace{a + b + \cdots + z}_{26}\)\int_0^{\frac{\pi}{2}} \cos\theta d\theta\(\int_0^{\frac{\pi}{2}} \cos\theta d\theta\)
\frac{x^2}{1 + x + \cdots + x^n}\(\frac{x^2}{1 + x + \cdots + x^n}\)x^{\frac{2}{k + 1}}\(x^{\frac{2}{k + 1}}\)
\sum_{i = 1}^{n}\(\sum_{i = 1}^{n}\)\prod_\epsilon\(\prod_\epsilon\)

數學符號
