Works damned well...
$$\zeta (2)=\sum _{ n=1 }^{ +\infty }{ \frac { 1 }{ { n }^{ 2 } } } =\frac { { \pi }^{ 2 } }{ 6 } $$

Wow, I'm also impressed:

$$\tilde{\mathfrak{S}}_{N, \eta}(\nu_{k})\approx\frac{1}{\pi}\int_{\mathbb{R}}\mathrm{d}\omega\,S(\omega)\,​\frac{\eta}{(\nu_{k}-\omega)^{2}+\eta^{2}}\quad\text{for}\quad k=1, 2, \dots, M$$
