“Geometry: An Interactive Journey to Mastery” S:1 E:16 Circle-ometry – On Circular Motion

S:1 E:16 Circle-ometry – On Circular Motion How can you figure out the “height” of the sun in the sky without being able to measure it directly with a ruler? Follow the path of ancient Indian scholars to answer this question using “angle of elevation” and a branch of geometry called trigonometry. You learn the basic trig identities (sine, cosine, and tangent) and how physicists use them to describe circular motion.
