1 Trigonometric Identities
About this lesson
Lecturer explores fundamental trigonometric identities, starting with Pythagorean trigonometry (sin²θ + cos²θ = 1) from GCSE, derived using a unit circle and right triangle. They then define reciprocal trig functions and expand upon the initial identity to derive two more: cot²θ = cos²θ and tan²θ = sin²θ/cos²θ.
