\(sin\alpha \cdot cos\beta = \left(\displaystyle\frac{sin(\alpha + \beta) +sin(\alpha – \beta)}{2}\right)\)

\(cos\alpha \cdot cos\beta = \left(\displaystyle\frac{cos(\alpha + \beta) + cos(\alpha – \beta)}{2}\right)\)

\(sin\alpha \cdot sin\beta = \left(\displaystyle\frac{cos(\alpha – \beta) – cos(\alpha + \beta)}{2}\right)\)
