<p>Trigonometry can be re-engineered by taking the plane itself as unit of measurement. The angular circle has circumference 1. There are variables {X, Y} on the unit circle such that X^2 + Y^2 = 1. The functions xur and yur relate the angles on the angular circle to the points {X, Y}. This notion was in "Trig rerigged" in 2008 and was adopted in the books "Elegance with Substance" 2009 and "Conquest of the Plane" 2011. The update in 2016 concerns the disk with the area rather than the circumference. This is still a draft text but gives a relevant overview.</p>
