NIST Digital Library of Mathematical Functions (DLMF)

This resource is the Web counterpart to NIST Handbook of Mathematical Functions, published by Cambridge University Press. It replaces the Handbook of Mathematical Functions with Formulas, Graphs, and Mathematical Tables, published in 1964 by the National Bureau of Standards and edited by M. Abramowitz and and I. A. Stegun. All of the mathematical information contained in the printed handbook is also contained in the DLMF, along with additional features such as more graphics, expanded tables, and higher members of some families of formulas. Consequently, the printed handbook has occasional gaps in the numbering sequences of equations, tables, and figures. DLMF has many active links including definitions of symbols and to external sources of reviews, full texts of articles, and items of mathematical software.

The Wolfram Functions Site

The Wolfram Functions Site consists of a comprehensive database of mathematical functions. Access to the functions is provided by keyword search, or browsing by category or alphabetically. The site also contains collections of visualizations, notations, and identities.
