Although Mathematica has the most complete numeric and symbolic implementation of mathematical functions, scientists and engineers regularly need to consult handbooks, tables, primary references, and the internet, to determine the properties of special functions. Such properties include special cases, identities, sum formulas, series expansions (especially asymptotics), and differential equations. Prior to the development of the Wolfram Functions Site, functions.wolfram.com, one would have to locate the required formula, implement it, check the implementation and, quite often, check its validity.
The Wolfram Functions Site makes a revolutionary change to this process: it is easy to use and its tight integration with Mathematica permits, in most cases, direct implementation and testing of any formula. Content-based searching enables queries for identities that include a specific function.
In this talk I will provide a user’s perspective on the Wolfram Functions Site, showing how Mathematica was used in conjuction with the Wolfram Functions Site to solve a number of research problems.
The developers of the Wolfram Functions Site, Oleg Marichev and Michael Trott, are to be congratulated for providing the scientific community with a most valuable resource.
