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 one of the Pythagorean Identities, we can expand this double-angle formula for cosine and get two more variations. The first variation is:TRIGONOMETRIC FORMULAS Basic Identities The functions cos(θ) and sin(θ) are defined to be the x and y coordinates of the point at an angle of θ on the unit circle. Therefore, sin(−θ) = −sin(θ), cos(−θ) = cos(θ), and sin2(θ) + cos2(θ) = 1. The other trigonometric functions are defined in terms of sine and cosine:Product-to-Sum Identities - These identities turn products of trigonometric functions into sums of trigonometric functions. One example is $2cosxcosy = cos(x-y)+cos(x+y)$. Then there are other, more complicated trigonometric identities such as Lagrange's Identity that deal with series.
