Trigonometry through Algebra: No more Sine and Cosine or Tangent

Mathematics students have good cause to celebrate. 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 simple framework means calculations can be done without trigonometric tables or calculators, yet often with greater accuracy.

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.

Personally I enjoyed trigonometry, but I am sure it will be a cause of celebration for many.
