Simplify cos(theta)^2-sin(theta)^2 - Mathway
Since both terms are perfect squares, factor using the difference of squares formula, a2 −b2 = (a+b)(a−b) a 2 - b 2 = (a + b) (a - b) where a = cos(θ) a = cos (θ) and b = sin(θ) b = sin (θ). (cos(θ)+sin(θ))(cos(θ)−sin(θ)) (cos (θ) + sin (θ)) (cos (θ) - sin (θ))
