LaTeX tips for student(me)

Last updated at Posted at 2019-12-01

はじめに

引き続き, B2のJabelicです. 明治大学/明治大学大学院 AdventCalendar 2019 2日目の記事です.
ちょっと特殊というか, たまーに使うものを列挙. 完全に自分用のメモになってしまいますが.

数式を縦に並べたいとき


\begin{equation*}
\hat{w}\ x + \hat{b} = 
     \left\{
     \begin{aligned}
          \geq 0 \hspace{5mm}\Longrightarrow\hspace{5mm}G_1\\
          < 0 \hspace{5mm}\Longrightarrow\hspace{5mm}G_2\\
     \end{aligned}
     \right.
 \end{equation*}
\begin{equation*}
\hat{w}\ x + \hat{b} = 
     \left\{
     \begin{aligned}
          \geq 0 \hspace{5mm}\Longrightarrow\hspace{5mm}G_1\\
          < 0 \hspace{5mm}\Longrightarrow\hspace{5mm}G_2\\
     \end{aligned}
     \right.
 \end{equation*}

左右に配置したいとき


\begin{equation}\
     \begin{aligned}\
\verb|\begin{equation}|\\
\verb|\begin{matrix}|\\
\verb|a_{11}&a_{12}\\|\\
\verb|a_{21} & a_{22}\\|\\
\verb|\end{matrix}|\\
\verb|\end{equation}|\\
     \end{aligned}\
     \quad \text{$\hspace{10mm}\Longrightarrow\hspace{10mm}$}\
     \begin{aligned}\
\begin{matrix}\
a_{11}&a_{12}\\
a_{21} & a_{22}\\
\end{matrix}\
     \end{aligned}\
\end{equation}\
\begin{equation}\
     \begin{aligned}\
\verb|\begin{equation}|\\
\verb|\begin{matrix}|\\
\verb|a_{11}&a_{12}\\|\\
\verb|a_{21} & a_{22}\\|\\
\verb|\end{matrix}|\\
\verb|\end{equation}|\\
     \end{aligned}\
     \quad \text{$\hspace{10mm}\Longrightarrow\hspace{10mm}$}\
     \begin{aligned}\
\begin{matrix}\
a_{11}&a_{12}\\
a_{21} & a_{22}\\
\end{matrix}\
     \end{aligned}\
\end{equation}\

化学組版

TeXによる化学組版
これがすごい. ヤバイ

化学式

プリアンブルに
\usepackage[version=3]{mhchem}


\[\ce{HA + H_2O <=>[K^+][K^-] A^- + H3O^+ }\cdots(5.1)\]

ベンゼン環

TeXによる化学組版の”picture環境によるベンゼン環の描画”から定義を引用してdocs.texをファイル内に置く.


\[\ce{ COOH{\para} NO2 <=> H+ + COO- {\para} NO2}\]

フォントサイズを強制的に変更する

プリアンブルに以下を入れる.


\usepackage[truedimen,mag=1000]{geometry}%フォントサイズを指定. 1000が10pt

これより前に\usepackage{geometry}を置いてしまっているとコンパイルが通らないので気をつけてね
