Beamer and Prosper are utilities for creating presentation slides using LaTeX. Both are good packages so a choice between them is a personal decision. I started out using Prosper but now I use Beamer. Go to one of my tutorials in Beamer: A Quickstart or Prosper: a tutorial to learn more about them.
If you have to do partial fractions by hand, you might as well do them the right way. Read Partial Fractions Done Right to find out how.
Dynagraph is a graphics utility for plotting beautiful curves and surfaces. It is written entirely in C. The graphics are done in OpenGL and the user interface is done in xforms. It runs in the X Window System under Unix.
I wrote Dynagraph many years ago and I haven't done much to keep it up to date, or add features, or fix its (many) bugs. My plan is to rewrite it from scratch in Scheme and GTK+, when I find some free time.
In the mean time, you may visit Dynagraph's Gallery and it if you find what you see there useful, then download the source and compile to run it on your computer.
My Geometry page contains a motely collection of problems and puzzles of elementary geometry.
There is no reasons for having these photos here other than they are cute.
If you have seen the movie La Marche de l'empereur / March of the Penguins, you may think that the photos below are somehow related to that movie. But they are not. These were taken from Guillaume Dargaud's website http://www.gdargaud.net/Antarctica/Penguins.html long before that movie was made.

Ah, and this one…. I don't remember where I got it from. I will be glad to add credit if you know who made it.
