Latex test

Note to self: wikia doesnt support certain LaTeX commands. Fix this

Failed to parse (unknown function "\documentclass"): {\displaystyle \documentclass{article} \usepackage{amsmath} \begin{document} \[ \begin{Bmatrix} 1 & 0 & 0 & 0 \\ 0 & 1 & 0 & 0 \\ 0 & 0 & 1 & 0 \\ 0 & 0 & 0 & 1 \end{Bmatrix} \] \end{document}}

$L_{r}=\frac{L_{s}}{(P-L_{r}),P}$

$\lim\limits_{T\to\infty} \frac{T\;L_r}{T-L_r}=L_r$

$\lim\limits_{L_r\to\infty} \frac{T\;L_r}{T-L_r}=-T$
