<DIV>I read a report the other day about Norman Wildberger's "Rational
Trigonometry" which supposedly does away with sines, cosines, and tangents and
allows for using algebra and simple arithmetic. It is also supposedly more
accurate. I hadn;t seen anyone here comment on this and I was wondering if
anyone has had a chance to review his work.</DIV></DIV> <BR> </BODY></HTML>
