Trigonometric Dual Laws and the Parallax Formula - Universal Hyperbolic Geometry

Explore trigonometric dual laws and the Parallax formula in Universal Hyperbolic Geometry through this 36-minute lecture. Learn about the Right parallax formula, an analog to the Angle of parallelism formula in classical hyperbolic geometry. Discover dual laws of main trigonometric laws, prove the Right parallax theorem using the Cross dual law, and understand its relation to Lobachevsky and Bolyai's classical result. Delve into topics like Pythagoras' theorem, Triple spread formula, Zero quadrance theorem, and Zero spread theorem. Gain insights into Isosceles parallax and General parallax formulas through provided exercises.
