The following

$$ \int_{a}^{b} x^2 dx $$

Is an integral

$$
 \varphi = 1+\frac{1} {1+\frac{1} {1+\frac{1} {1+\cdots} } } 
$$

Enable Katex in the config file by setting the `katex` param to `true`. This will import the necessary Katex CSS/JS. 

See the online reference of [supported TeX functions](https://katex.org/docs/supported.html). 

**Note:** For inline math to render correctly, your content file extension must be `.mmark`. See the [official mmark site](https://mmark.nl/). 

```
Inline math: $$ \varphi = \dfrac{1+\sqrt5}{2}= 1.6180339887… $$
