# Math & TeX

Vous pouvez utiliser le format mathTeX pour inclure des formules mathématiques dans votre documentation. Nous proposons cela via la [KaTeX](https://katex.org/docs/supported.html) bibliothèque.

Vous pouvez également ajouter mathTeX [sous forme de contenu en ligne](/docs/documentation/fr/creating-content/formatting/inline.md#math-and-tex).

### Exemple de bloc Math & TeX

$$
s = \sqrt{\frac{1}{N-1} \sum\_{i=1}^N (x\_i - \overline{x})^2}
$$

### Représentation en Markdown

$$f(x) = x \* e^{2 pi i \xi x}$$

```markdown
# Bloc Math et TeX

$$f(x) = x * e^{2 pi i \xi x}$$
```

# Agent Instructions: 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:

```
GET https://gitbook.com/docs/documentation/fr/creating-content/blocks/math-and-tex.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
