− | '''LaTeX''' is a typesetting language used primarily to type mathematical expressions in an elegant fashion. For example, without LaTeX, <math>\frac{35}{137}</math> would have to be written as 35/137. To use LaTeX in the forums, enclose your LaTeX code with dollar signs: <math>your codes here</math>. To use LaTeX on AoPSWiki, enclose your code with math tags instead of dollar signs, like so: <nowiki><math>your codes here</math></nowiki>
| + | {{Latex}} |
| + | The <math>\text{\LaTeX}</math> typesetting system (typically pronounced "lay-tex", but also sometimes "lay-tek", "lah-tek", or "lah-tex") is widely used to produce well-formatted [[math|mathematical]] and scientific writing. <math>\text{\LaTeX}</math> is very handy for writing equations such as |
| | | |
− | CHANGE: Dollar signs can now be used to use LaTeX.
| + | <cmath>\sqrt[3]{4^2+\frac{5}{3}+\pi} \approx 2.75</cmath>. |
| | | |
− | ==Useful Codes==
| + | Nearly every serious student of maths or science will use <math>\text{\LaTeX}</math> frequently. Through these websites, you will learn what you'll need to express maths and science like a professional, much, much better than Microsoft Word! |

− | Note that on AoPSWiki, many codes that work on the AoPS forums do not work. Also, a helpful tip is that if LaTeX fails to render within AoPSWiki, try adding the code \displaystyle to the beginning of the string of LaTeX. This often fixes minor rendering problems.

− | Also note that you do not have to use braces, "{" and "}", when you only want one character in the operation.
