The Triple Spread Formula, Circumcircles and Curvature - Rational Geometry Math Foundations
Offered By: Insights into Mathematics via YouTube
Course Description
Overview
Explore the projective Triple quad formula, also known as the Triple spread formula in Rational Trigonometry, and its relationship to curvature in this 24-minute mathematics lecture. Delve into the concept of a triangle's circumcircle and learn how to determine its size using the three side quadrances. Discover the connection between the fundamental Triple quad formula and its projective version. Examine the definition of quadratic curvature as the reciprocal of circumquadrance. Investigate the relationship between projective 1-points and the core circle to understand how the projective triple quad formula links one-dimensional and two-dimensional geometries. Topics covered include the core circle, dilation factors, circumquadrance calculations, and circle quadratic curvature.
