# 如何插入并引用公式

这是由21个视频组成的系列中的第12个视频，作者为 [文森特·奈特博士](http://bit.ly/186ai3Z) 卡迪夫大学。在 LaTeX 中，我们可以为公式添加标签，以便在文章中轻松引用。这里我们将看到如何使用 `\begin{equation}` 和 `\end{equation}` 这些命令。该公式会自动编号，并且通过添加一个 `\label` 命令，我们就可以在文档其余部分的任何位置使用 `\ref` 该命令。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ayakaleaf-pro.ayaka.space/latex/zh-cn/wen-da/51-how-to-include-and-reference-equations.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
