# 如何加入並引用方程式

這是 21 部系列中的第 12 部影片，由 [Vincent Knight 博士](http://bit.ly/186ai3Z) 卡地夫大學。在 LaTeX 中，我們可以為方程式加上標籤，方便在文章中參照。這裡我們將看到如何使用 `\begin{equation}` 和 `\end{equation}` 指令建立方程式。這個方程式會自動編號，而只要加入一個 `\label` 指令，我們就可以在文件其餘部分的任何地方，使用 `\ref` 指令。

# 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://overleaf-pro.ayaka.space/latex/zh-tw/wen-yu-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.
