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 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.
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.

BUGS

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