Financial Engineering and Mathematics – subject guide

An online project at the National Institute of Standards and Technology (NIST) to develop a major resource of mathematical reference data for special functions and their applications.

The Mathematical Functions Site was created as a resource for the educational, mathematical and scientific communities. It contains the world's most encyclopedic collection of information about mathematical functions. The site also details the interrelationships between the special functions of mathematical physics and the elementary functions of mathematical analysis as well as the interrelationships between the functions in each group.
