More math $\xi_{(even-in-the-title-!)}$

Wow this really works !

A compilation of $\LaTeX$ formulas…

Matrix

$$ \begin{matrix} \alpha& \beta^{*}\\ \gamma^{*}& \delta \end{matrix} $$

$$ \begin{bmatrix} \alpha& \beta^{*}\\ \gamma^{*}& \delta \end{bmatrix} $$

$$ \begin{Vmatrix} \alpha& \beta^{*}\\ \gamma^{*}& \delta \end{Vmatrix} $$

Limits

$$ \lim_{n \to \infty} \sum_{k=1}^n \frac{1}{k^2} = \frac{\pi^2}{6} $$

$$ \lim_{n \to \infty} \frac{1}{x^n} = 0 $$

Various symbols

$$\lambda,\xi,\pi,\theta, \mu,\Phi,\Omega,\Delta$$
