This is the formula for the general case, where the period is T. As mentioned before, for the sake of convenience, we consider the case, where T = 2π. and now we will derive those formulas using the knowledge of the orthogonal system equipped in the previous part.

WebbThe product-to-sum identities are used to rewrite the product between sines and/or cosines into a sum or difference. These identities are derived by adding or subtracting the sum and difference formulas for sine and cosine that were covered in an earlier section. For example, sin(α – β) = sin α cos β ...
