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.
