**The law of cosines**, commonly referred to as the **cosine rule or the cosine formula** in trigonometry, basically connects the length of the triangle to the cosines of one of its angles. It claims that we can determine the length of the third side of a triangle if we know the length of the first two sides and the angle between them. It may be calculated using the equation c2 = a2 + b2 – 2ab cosγ, where a, b, and c are the triangle's sides and γ is the angle between a and b.
