Hi,
Thank's for any help

To use it on this site it is not necessary to download it. Just type the appropriate code, for example:

Code:
[tex]\sqrt{x^{3y+1}}\sin\left(\frac{e^x}{a_2}\right) \ge\cos(y)[\tex]
produces $\sqrt{x^{3y+1}}\sin\left(\frac{e^x}{a_2}\right) \ge\cos(y)$.

You don't have to download anything. You simply enclose your code with the TEX tags (use the sigma button to generate the tags). There are many good tutorials available online, just do a search for them.
