# 包含显示数学公式（方程和公式）

这是由……制作的 21 个视频系列中的第 11 个视频 [文森特·奈特博士](http://bit.ly/186ai3Z) 卡迪夫大学的。除此之外 [在句子中包含数学内容](/latex/zh-cn/wen-da/72-including-inline-mathematics-in-latex-documents.md)，我们可以单独显示方程和公式。在本教程中，我们将学习如何编写简单方程，并介绍以下命令 `\frac` 用于分数以及 `\sum` 用于求和。

# 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/71-including-displayed-mathematics-equations-and-formulae.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.
