\mapsto💡 如何使用 LaTeX 符号
LaTeX 符号是用于数学排版和科学文档中的特殊字符。要使用任何符号，只需将 LaTeX 命令复制并粘贴到 LaTeX 文档中的数学模式 ($...$) 或显示模式 ($$...$$) 内。
快速示例：
\documentclass{article}
\usepackage{gensymb}
\begin{document}
The formula is $E = mc^2$ where $c \approx 3 \times 10^8$ m/s
Greek letters: $\alpha, \beta, \gamma, \Delta$
\end{document}点击上面的任何符号以查看详细的使用示例、替代方法和常见用例。
