Nous proposons cela via la [KaTeX](https://katex.org/docs/supported.html) bibliothèque. Vous pouvez également ajouter mathTeX [sous forme de contenu en ligne](/url/gitbook.com/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 This documentation is published with GitBook.
