How to write Latex formulas in wordpress sites? WP KATEX PLUGIN

Have you ever wanted to put your Latex formulas or entire research papers to your wordpress blog?  You can do this easily with WP Katex plugin from Andrew Sun. I recommend to read more details about this program in Andrew’s website if you are interesting of using it heavily.
When WP Katex is installed, just put latex in brackets [ ] before the formula and /latex in [ ] brackets after it. Here are few of the examples:

\mathcal{L}(s)= \sum\limits_{m=1}^{\infty}\frac{a(m)}{m^s} \Lambda_{\mathcal{L}}(s) = w \overline{\Lambda_{\mathcal{L}}(1-\overline{s})} D_{\mathcal{L}} = \left \{ s\in \mathbb{C}: \max \left( \frac{1}{2}, 1 – \frac{1}{d_{\mathcal{L}}} \right) <\sigma <1 \right \}

Source code (if you use: display=”true”, then your formulas will be centered like in $$ $$ mode):
