• Mar 9, 2026 the ark of mathematics part 2 proving trigonometr gonometric identities. Definitions: For any angle θ, the point on the unit circle is (cos(θ), sin(θ)) The radius is 1, so: x = cos(θ) y = sin(θ) Proof of the Pythagorean Identity Using the Unit Circle Since the point (cos(θ), sin(θ)) lies on the circle x² + By Jamal Schaefer
