WebJun 1, 2024 · First, starting from the sum formula, cos(α + β) = cos α cos β − sin α sin β ,and letting α = β = θ, we have. cos(θ + θ) = cosθcosθ − sinθsinθ cos(2θ) = cos2θ − sin2θ. Using the Pythagorean properties, we can expand this double-angle formula for cosine and get two more variations. The first variation is:
