General Solution of Equation cos²θ = cos²α

General Solution of Equation cos²θ = cos²α General Solution of Equation cos²θ = cos²α (or) sin²θ = sin²α: cos²θ = cos²α (since cos²θ + sin²θ = 1 ⇒ cos²θ = 1 – sin²θ)  (1 – sin²θ) = (1 – sin²α) (1 – sin²θ) – (1 – sin²α) = 0 sin²θ = sin²α sin²θ – sin²α Read more about General Solution of Equation cos²θ = cos²α[…]
