NAME

       derivations - book: Derivations of Applied Mathematics

DESCRIPTION

       For  various  valid  reasons,  open-source  program sources rarely derive the mathematical
       formulas they use.  A user, nevertheless -- not wishing to take such formulas on faith  --
       might wish to see such formulas somewhere derived.

       Derivations  of  Applied  Mathematics  is  a book that derives, and documents, many of the
       mathematical formulas and methods  open-source  programs  use,  and  indeed  many  of  the
       formulas  and  methods used in science and engineering generally.  For example, it derives
       and documents 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.pdf with a PDF reader like (for example) evince(1).

BUGS

       The book remains 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 Debian distributes them.   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>.
