HyperMath is "a growing collection of examples of applied mathematics with links to their applications to problems in physics and astronomy." The author, Carl R. (Rod) Nave of the Department of Physics and Astronomy at Georgia State University, does not claim that the website material is complete, noting that he has been adding to the project on an as-needed basis through the process of developing the HyperPhysics material. (A link will take you to the HyperPhysics site.) The interactive format lets you choose topics on a diagram and enter numbers to get results. Topics include Trigonometry, Calculus, Differential Equations, Algebra, Geometry, Exponents, Vectors, and Algorithms. Visitors are then presented with formulas, functions, links to related topics and applications, and online forms that will perform some of the calculations as a way to demonstrate the mathematics.
