DERIVATIONS(7)						Derivations of Applied Mathematics					    DERIVATIONS(7)

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.

FILES

       /usr/share/doc/derivations/derivations.ps.gz
	      the book in postscript format
       /usr/share/doc/derivations/derivations.pdf.gz
	      the book in PDF

BUGS

       The book is a work in progress.
