# Mathematics using MathJax

I’ve added the MathJax plugin to the forum site so it should be possible to add equations now. In-line equations \psi_0 =10^4 using the $...$ pairing and display equations with $$...$$

\nabla^4 \psi = \frac{g \rho \alpha}{\eta} \frac{\partial T}{\partial x}

See settings / plugins for options that can be changed. Source code is from here: https://github.com/discourse/discourse-math.git
