Specifically, a new way to do Trig.

Mathematics students have cause to celebrate. A University of New South Wales academic, Dr Norman Wildberger, has rewritten the arcane rules of trigonometry and eliminated sines, cosines and tangents from the trigonometric toolkit.

His book explaining the method is called Divine Proportions: Rational Trigonometry to Universal Geometry (not available at Amazon, yet).

Dr Wildberger has replaced traditional ideas of angles and distance with new concepts called "spread" and "quadrance".

These new concepts mean that trigonometric problems can be done with algebra," says Wildberger, an associate professor of mathematics at UNSW.

"Rational trigonometry replaces sines, cosines, tangents and a host of other trigonometric functions with elementary arithmetic."

This could revolutionize mathematics who knows where it could lead? Sometimes all that's needed is to look at something from a different vantage point to make exciting things happen.

Thanks to Transterrestrial Musings for the pointer.
