Latex support on this website

This website uses MathJax, a JavaScript library able to compile and render latex live in your browser. The syntax is fully explained here: https://wordpress.org/plugins/mathjax-latex/. Briefly:

•  display style formulas can be obtained as in the standard latex syntax by typing them between double dollars or escaped square brackets ($$ ... $$ or \[ ... \] );
• inline style formulas use the slightly non-standard syntax $latex ... $ or \( ... \).

Examples:

• $latex e^{i\pi} + 1 = 0$ is rendered as $latex e^{i\pi} + 1 = 0$;
•  \(\int_0^1 x dx = \frac12\) is rendered as \(\int_0^1 x dx = \frac12 \);
• finally  $$\|z\| = 0$$ is rendered as  $$\|z\| = 0.$$

You can freely use mathematical formulas in comments and posts.
