==== Typing mathematical symbols ====

There are two ways
    * **Using LaTex code (via ΜathJax)**

In the html editor just type LaTex code between symbols ''\( ... \)'' (inline).

If you wish to have mathematical symbols in one line per line (display math) just type LaTex code between symbols ''\[ ... \]'' or ''$$ ... $$''

__Example__:

  \[S(f)(t)=a_{0}+\sum_{n=1}^{+\infty}a_n \cos(n \omega t)+b_n \sin(n \omega t)\]
  

For further convenience, click in the editor icon "Latex" (see image below).

A second math editor will pop up. Just choose the desired math symbol and the latex code will be created automatically.
