# LaTeX Packages

LaTeX is very useful in its own right, but what makes it
overwhelmingly powerful is all the additional packages that
people all over the world have developed for it over the many
years of its existence. Some of these packages are all but
essential. For example, we have seen that the best way to
get an image into a document is to use the `graphicx`
package:

`\usepackage{graphicx}`

Likewise, we can use other packages to gain a good
deal of power in typesetting our documents. Here are some
of the most useful packages.

Package | Use | Sample Macros |
---|---|---|

amsfonts | Additional mathematical fonts | \mathbb |

amsmath | Additional mathematical macros | \align \multline \split |

amssymb | Additional mathematical symbols | \daleth |

color | Put color in documents | \textcolor{color}{text} \pagecolor{color} \definecolor{name}{rgb}{rgb triplet} |

enumerate | Extra enumeration options | \begin{enumerate}[a)] |

float | Create new floating environments | \floatstyle \newfloat{name}{place}{counter}[] |

graphicx | Insert graphics | \includegraphics |

leqno | Put equation numbers on left side | |

sidecap | Place caption beside figure | \begin{SCfigure} |

subfig | Place figures side by side | \subfloat[caption]{includegraphics...} |

wrapfig | Float figure to side | \begin{wrapfigure}{pos}{width} |

The "final exam" for this course will take place
at 8:00 AM on Tuesday, 12 December. This will be an ordinary
50 minute test. It will be comprehensive, but weighted toward
the latter half of the semester. As always, paper notes will
be permitted, but no electronic devices will be allowed.
