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

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