KaTeX demo
Including mathematical notations in your post is possible thanks to KaTeX.
To add a math notation all you need to do is add $$ signs at the beginning and end of the notation.
An example for you guys,
$$f(x) = \int_{-\infty}^\infty \hat f(\xi)\,e^{2 \pi i \xi x} \,d\xi$$
Will produce the following notations,
\[f(x) = \int_{-\infty}^\infty \hat f(\xi)\,e^{2 \pi i \xi x} \,d\xi\]Math can be fun for sure!
