## NAME

derivations - book: Derivations of Applied Mathematics## DESCRIPTION

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 math‐ ematical formulas and methods implemented in free software or used in science and engi‐ neering generally. It documents and derives the Taylor series (used to calculate trigono‐ metrics), the Newton-Raphson method (used to calculate square roots), the Pythagorean the‐ orem (used to calculate distances) and many others.## READING THE BOOK

Among other ways, you can read the book on your computer screen by opening the file /usr/share/doc/derivations/derivations.ps.gz with the gv(1) program under X(7). To print the book on a standard postscript printer, just zcat(1) then lpr(1) the same file.## FILES

The book is a work in progress.## AUTHOR

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 <@debian.org>. However, most e-mail will naturally be about the book itself: this should be sent to <thb@deriva‐ tions.org>.## COPYLEFT
