This video is all about trigonometry, focusing on reviewing everything you are likely to actually use regularly in calculus. Instead of having to memorize a million trig identities I want to show how you can understand trig, where the formulas come from, and how you can figure them out on your own if you randomly need one in the middle of a test. 0:00 Trig Intro 0:40 Unit Circle Definitions 2:21 Why Radians 3:30 Pythagoras 4:02 Graphing cos and sin from unit circle 5:31 Special triangles 8:27 Computing Weird Trig Values 9:52 The other Trig Functions 10:49 Graphing Tan etc 13:31 Geometric Meaning of Sec and Tan 12:27 Other Pythagorean Identities 14:36 Trig Identities 16:27 Geometric Proof of Sum Rule 19:34 Brilliant.org/TreforBazett BECOME A MEMBER: ►Join:    / @drtrefor   MATH BOOKS I LOVE (affilliate link): ► https://www.amazon.com/shop/treforbazett COURSE PLAYLISTS: ►DISCRETE MATH:    • Discrete Math (Full Course: Sets, Log...   ►LINEAR ALGEBRA:    • Linear Algebra (Full Course)   ►CALCULUS I:    • Calculus I (Limits, Derivative, Integ...   ► CALCULUS II:    • Calculus II (Integration Methods, Ser...   ►MULTIVARIABLE CALCULUS (Calc III):    • Calculus III: Multivariable Calculus ...   ►VECTOR CALCULUS (Calc IV)    • Calculus IV: Vector Calculus (Line In...   ►DIFFERENTIAL EQUATIONS:    • Ordinary Differential Equations (ODEs)   ►LAPLACE TRANSFORM:    • Laplace Transforms and Solving ODEs   ►GAME THEORY:    • Game Theory   OTHER PLAYLISTS: ► Learning Math Series    • 5 Tips To Make Math Practice Problems...   ►Cool Math Series:    • Cool Math Series   SOCIALS: ►X/Twitter: http://X.com/treforbazett ►TikTok:   / drtrefor   ►Instagram (photography based):   / treforphotography
