Wikipedia:
 * In trigonometry, the law of cosines (also known as the cosine formula or cosine rule) relates the lengths of the sides of a triangle to the cosine of one of its angles. Using notation as in Fig. 1, the law of cosines states
 * $$c^2 = a^2 + b^2 - 2ab\cos\gamma,$$
 * where $γ$ denotes the angle contained between sides of lengths $a$ and $b$ and opposite the side of length $c$.
