## $\KaTeX$
|
|
|
|
[$\KaTeX$](https://katex.org/) is a fast and easy-to-use library that enables the rendering of mathematical notation, using LaTeX syntax.
|
|
|
|
You can use $\KaTeX$ **inline** by wrapping the expression between `$` or between `\\(` and `\\)`.
|
|
|
|
For example, `$ \sin(x) = \sum_{n=0}^{\infty} \frac{(-1)^n}{(2n + 1)!} x^{2n + 1} $` would render: $ \sin(x) = \sum_{n=0}^{\infty} \frac{(-1)^n}{(2n + 1)!} x^{2n + 1} $
|
|
|
|
To display the expression **on its own line and centered**, wrap it around `$$` or between `\\[` and `\\]`.
|
|
|
|
For example, `\\[ r = \frac{\sum_{i=1}^{n}(x_i - \bar{x})(y_i - \bar{y})}{\sqrt{\sum_{i=1}^{n}(x_i - \bar{x})^2}\sqrt{\sum_{i=1}^{n}(y_i - \bar{y})^2}} \\]` renders: \\[ r = \frac{\sum_{i=1}^{n}(x_i - \bar{x})(y_i - \bar{y})}{\sqrt{\sum_{i=1}^{n}(x_i - \bar{x})^2}\sqrt{\sum_{i=1}^{n}(y_i - \bar{y})^2}} \\]
|
|
|
|
To activate $\KaTeX$ for a post, include `katex = true` within the `[extra]` section of the post's front matter. For enhanced performance and security, the JavaScript, CSS, and fonts are hosted locally.
|
|
|
|
**Note**: After enabling $\KaTeX$, if you want to use \$ without rendering a mathematical expression, escape it with a single backslash: `\$`.
