Spy der Mann writes "Dr. Norman Wildberger, of the South Wales University, has redefined trigonometry without the use of sines, cosines, or tangents. In his book about Rational Trigonometry (sample PDF chapter), he explains that by replacing distance and angles with new concepts:
quadrance, and spread, one can express trigonometric problems with
simple algebra and fractional numbers. Is this the beginning of a new
era for math?"
