A site at the University of Tennessee at Martin includes some pages on graph theory, including a tutorial on Euler and Hamiltonian circuits. It includes an interesting story on the origin of the phrase `Hamiltonian circuit'. An explanation (using too much mathematical notation?) of minimal spanning trees (I'm looking for a better one..) Another page on minimal spanning trees...still too much math... A page about greedy algorithms, e.g., Kruskal's algorithm; again, a bit too much notation...
A site called SOS Math at the Univ. of
Texas at El Paso offers pages of material on topics ranging from polynomial long
division, the quadratic formula, and trigonometric identities, to Taylor polynomials,
the CauchyRiemann equations, and Matrix algebra. Dan Sloughter has a web page containing Java programs for visualizing various mathematical concepts. My favorite is one which will draw the Taylor polynomial approximations for y=sin(x) . Forget a geometry formula? Check this page at Trinity College. A Javaenabled page for generating Pascal's triangle (or rather, the last two digits of each entry, which is good enough through the 24th line). What's the pattern of the even numbers in the triangle?!
