The general rational laws of trigonometry | WildTrig: Intro to Rational Trigonometry

We establish the laws of rational trigonometry in the very general planar setting of having a general bilinear form which determines the notions of quadrance and spread. Pleasantly the laws of RT are still the familiar ones, but the interest is in seeing just how elegantly and simply these
