# Mathematical formulas in the SimScale forum

#1

Fellow SimScale users,

@mmazo just updated the forum with a cool new option to type in mathematical formulas. Quick demo:

When a \ne 0, there are two solutions to (ax^2 + bx + c = 0) and they are
$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$

It also supports tensor/matrix notion:

\begin{vmatrix} \mathbf{i} & \mathbf{j} & \mathbf{k} \ \frac{\partial X}{\partial u} & \frac{\partial Y}{\partial u} & 0 \ \frac{\partial X}{\partial v} & \frac{\partial Y}{\partial v} & 0 \ \end{vmatrix}

Hope it helps!

We are using the webs most popular math javascript engine MATHJAX which allows you to use Tex on the forum editor.

All you have to do is use TeX markup inside the standard TeX delimiters, for example:

$$x = a + b^2$$


to get: $$x = a + b^2$$
