• Mar 19, 2026 Half Angle Trigonometric Identities double-angle formula for cosine: cos(2θ) = cos²θ - sin²θ. This seemingly simple equation holds the key. By manipulating this formula using the Pythagorean identity (sin²θ + cos²θ = 1), we can derive expressions for cos²θ and sin²θ in terms By Elwyn Vandervort
