# Getting Started With LaTeX

(pronounced 'lay-tek') is a sort of 'language' that, besides many other things, can be used to write mathematical equations in a form that a computer can display. Both our website and forum support LaTeX so here is a short guide to help you get started.

To use in a forum post you need to enclose it in [tex] tags like this:

[tex]a + b = c[/tex]

There are many symbols you can use. Here is a table containing some of the more useful ones:

LaTeX code | Produces |
---|---|

\pi | |

\sqrt{x} | |

\times | |

\frac{1}{2} | |

\div | |

\frac{a}{b} | |

\infty | |

a^2 | |

\pm | |

a^x | |

\leq | |

a_1 | |

\geq | |

a_x | |

\equiv | |

180^\circ | |

\neq | |

\pm | |

\therefore | |

\alpha | |

\int | |

\theta |

For example, if I wanted to post to the forum a question regarding the following quadratic equation…

…to have this formula appear in my post like this I would have to type the following:

[tex]x^2 + 11 x + 30[/tex]

These are just a few examples of the very many commands available. For the complete guide to using please check out *The Comprehensive* *Symbol List*. To download the guide you can click on the following link…
