87,160 formulas and 10,828 graphics about mathematical functions are now available free at The Wolfram Functions Site, an important new resource for mathematicians, scientists, engineers, and students at: http://functions.wolfram.com In the applications of mathematics to science and engineering--as well as in pure mathematics itself--there are several hundred so- -called "special functions" that have been intensively used for a century or more. These special functions--with names like Bessel functions, hypergeometric functions, and totient functions-- define focal points of mathematical knowledge. The Wolfram Functions Site provides in a readily accessible way the largest collection, by far, of such knowledge ever assembled. Several widely used handbooks of mathematical functions have been published, the largest of which contained about 15,000 formulas, meticulously compiled from thousands of technical papers. Traditional handbooks have also included only handfuls of graphics illustrating the properties of functions. With Mathematica, a huge number of new visualizations of functions have become possible. The Wolfram Functions Site assembles over 10,000 of these, with many more being planned. A major tour de force of reference website construction, The Wolfram Functions Site contains over 30 gigabytes of data. Material in The Wolfram Functions Site can be downloaded in several standard formats, including Mathematica InputForm and StandardForm, MathML, and PDF. Formulas can be copied from the site and immediately used as input to a computer system. For ease of citation, each formula has been assigned a unique permanent ID. While having already far surpassed previous knowledge bases for mathematical functions, continued growth is projected for The Wolfram Functions Site, with new searching capabilities, external contributions, and new classes of graphics and information.
