Book: derivations of applied mathematics
Understandably, program sources rarely derive the mathematical formulas they use. Not wishing to take the formulas on faith, a user might nevertheless reasonably wish to see such formulas somewhere derived.
Derivations of Applied Mathematics is a book which documents and derives many of the mathematical formulas and methods implemented in free software or used in science and engineering generally. It documents and derives the Taylor series (used to calculate trigonometrics), the Newton-Raphson method (used to calculate square roots), the Pythagorean theorem (used to calculate distances) and many others.

The book is a work in progress.
The book and this manpage are written by Thaddeus H. Black, who also maintains the Debian package derivations in which they are distributed. Users who need to contact the author in his role as Debian package maintainer can reach him at <[email protected]>. However, most e-mail will naturally be about the book itself: this should be sent to <[email protected]>.
