# 我該如何在 LaTeX 中建立角括號？

您可以在數學模式中使用 `\langle` 以及 `\rangle` 命令來建立尖括號，例如：

```latex
$\langle x \rangle$
```

如果您想在文字模式中使用它們，可以在 `textcomp` 文件前言中加入該套件，如下例所示：

```latex
\documentclass{article}
\usepackage{textcomp}
\begin{document}

您可以在文字中寫出尖括號，例如：  \textlangle x\textrangle。
\end{document}
```

## 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/27-how-do-i-create-angular-brackets-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.
