# 如何插入并引用公式

这是由……制作的 21 个视频系列中的第 12 个视频 [文森特·奈特博士](http://bit.ly/186ai3Z) 卡迪夫大学的。在 LaTeX 中，我们可以为公式添加标签，以便在文章中轻松引用。这里我们看看如何使用 `\begin{equation}` 和 `\end{equation}` 命令。这个公式会自动编号，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` 命令。

## 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://overleaf-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.
