Looking for a concise tutorial on elementary vector analysis? How about an animated introduction to chaos theory? Try the well-stocked Math Archives, a trove of links mainly for college math teachers and students. The hundreds of links, rated by level of difficulty, cover fields from abstract algebra to trigonometry. The sites offer a range of resources, including sample problems, simulations, and statistical data sets. Visitors can also download stacks of free educational software for everything from matrix manipulations to advanced calculus. The current links are mostly up to date, but site co-director Earl Fife of Calvin College in Grand Rapids, Michigan, is seeking funding to upgrade the collection.
