# 在 LaTeX 方程式中加入文字

這是 21 部系列影片中的第 13 支影片，由 [卡迪夫大學的 Vincent Knight 博士](http://bit.ly/186ai3Z) 卡迪夫大學的。有時我們希望在數學式中加入文字，而我們必須告訴 LaTeX 我們正在撰寫文字，否則它會將該單字視為一連串符號。這裡我們示範兩種正確格式化這類文字的方法，第一種使用 `\mbox` 指令，第二種則使用 `\text` 指令，而它需要 `amsmath` 套件。

# 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/73-including-text-within-equations-in-latex.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.
