LaTeX 数学符号
收集\(\LaTeX\)常用的数学符号命令
字母变体
常用命令有：\mathcal、\mathbb、\mathfrak、\mathsf、\mathbf、\boldsymbol、\mathit、\mathrm等。其中\mathcal、\mathbb仅适用于大写字母，其余命令大写、小写字母通用
\mathcal{A}：\(\mathcal A\)\mathbb{A}：\(\mathbb A\)\mathfrak{A}：\(\mathfrak A\)\mathsf{A}：\(\mathsf A\)\mathbf{A}：\(\mathbf A\)\boldsymbol{A}：\(\boldsymbol A\)\mathit{A}：\(\mathit A\)（无效果）\mathrm{A}：\(\mathrm A\)\mathscr{A}：\(\mathscr A\)（需要引入宏包mathrsfs）
