SUMMARY

Dr. Norman Wildberger has introduced a revolutionary method of trigonometry that eliminates traditional functions such as sine, cosine, and tangent, opting instead for an algebraic approach. This new method utilizes the concepts of quadrance and spread, which are claimed to provide greater accuracy and consistency with fundamental mathematical principles. The discussion raises questions about the credibility and acceptance of this method within the mathematical community.

PREREQUISITES
  • Understanding of basic algebraic principles
  • Familiarity with traditional trigonometric functions
  • Knowledge of mathematical properties such as distance and angles
  • Awareness of mathematical innovation and its implications
NEXT STEPS
  • Research Dr. Norman Wildberger's work on quadrance and spread
  • Explore the implications of algebraic trigonometry on existing mathematical theories
  • Investigate peer-reviewed articles discussing the credibility of Wildberger's method
  • Learn about alternative mathematical approaches to trigonometry
USEFUL FOR

Mathematicians, educators, students of mathematics, and anyone interested in innovative approaches to trigonometry and algebra.

I haven't been here for a long time, so sorry if this was already posted:

Dr Norman Wildberger has devised a new method of trigonometry that gets rid of sin, cos, tan (and the like) functions and uses algebra instead. It's supposedly straight forward, more accurate in a lot of cases, and more consistent with basic math.

it uses properties called quadrance and spread.

Does anybody know anything about this? Is it credible?
