The LaTex typesetting system is available here, for formatting math. Its use requires learning programming codes and syntax. You can google for tutorials and examples, but, unless you plan on using it a lot, the learning curve may not be worth the effort for you. (As an alternative to LaTex, thepurplemath siteexplains how to format math expressions using plain text, andthis other siteoffers many math symbols for copy-and-paste.)

Also, be forewarned that there are different implementations of LaTex on the Internet; not everything you may see elsewhere works the same way here (if at all).

At this site, each line (or set of lines) of LaTex coding must be enclosed within [tex]\text{[te}\text{x]}[/tex] and [tex]\text{[/te}\text{x]}[/tex] tags.

If you'd like to view the specific coding for any LaTex expressions in this forum, right-click the expression and use the pop-up menu to: Show Math As > TeX Commands.Here's an example of LaTex:

[tex]\displaystyle cos\bigg( \frac{\pi}{3} \bigg) \cdot \int_{a}^{b} \frac{3x^{3} + 7x - 10}{\sqrt[3]{x + 4}} \; \text{dx}[/tex]
