# 数学与 TeX

您可以使用 mathTeX 格式在文档中包含数学公式。我们通过以下方式提供此功能： [KaTeX](https://katex.org/docs/supported.html) 库。

您还可以添加 mathTeX [作为内联内容](/url/gitbook.com/docs/documentation/zh/creating-content/formatting/inline.md#math-and-tex).

### Math 和 TeX 块示例

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

### Markdown 中的表示

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

```markdown
# 数学与 TeX 块

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