LaTeX常用符号整理¶
笔者非数学系，整理LaTeX符号仅仅为Markdown公式编辑需要，存在不妥之处 (真的存在)。 参考文献已列于文末，其中包含完整的Latex符号公式表。 本文随笔者使用不断更新, 希望能帮助到大家。 希腊字母¶ Name Display Capital Case Display Var Case Display \alpha \(\alpha\) A \(A\) \beta \(\beta\) B \(B\) \gamma \(\gamma\) \Gamma \(\Gamma\) \theta \(\theta\) \Theta \(\Theta\) \vartheta \(\vartheta\) \mu \(\mu\) M \(M\) \delta \(\delta\) \Delta \(\Delta\) \epsilon \(\epsilon\) E \(E\) \varepsilon \(\varepsilon\) \sigma \(\sigma\) \Sigma \(\Sigma\) \varsigma \(\varsigma\) \pi \(\pi\) \Pi \(\Pi\) \varpi \(\varpi\) \omega \(\omega\) \Omega \(\Omega\) \xi \(\xi\) \Xi \(\Xi\) \zeta

\(O\)有代码的大写希腊字母，直接敲获得正体，使用\var前缀转化为斜体 如：\Gamma \(\Gamma\)（正） \varGamma \(\varGamma\)（斜） 没有代码的大写希腊字母，直接敲得斜体，使用\text命令转化为正体 如：T \(T\)直接敲（斜） \text T \(\text T\)（正） （也可以使用\rm将下一个单词变正，\text T的作用范围只是下一个字母；可以尝试加{}） 运算¶ 简单运算¶ Type Typeset + \(+\) - \(-\) \pm \(\pm\) \mp \(\mp\) \times \(\times\) \cdot \(\cdot\) \div \(\div\) \bmod \(\bmod\) \cap \(\cap\) \cup \(\cup\) \wedge \land \(\land\)
