In trigonometry, the law of cosines (also known as the cosine formula, cosine rule, or al-Kashi's theorem ) 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 $${\displaystyle c^{2}=a^{2}+b^{2}-2ab\cos \gamma ,}$$where … Meer weergeven Though the notion of the cosine was not yet developed in Euclid's time, his Elements, dating back to the 3rd century BC, contains an early geometric theorem almost equivalent to the law of cosines. The cases of Meer weergeven When a = b, i.e., when the triangle is isosceles with the two sides incident to the angle γ equal, the law of cosines simplifies significantly. Namely, because a + b = 2a = 2ab, the law of cosines becomes $${\displaystyle \cos \gamma =1-{\frac {c^{2}}{2a^{2}}}}$$ or Meer weergeven When the angle, γ, is small and the adjacent sides, a and b, are of similar length, the right hand side of the standard form of the law of cosines is subject to catastrophic cancellation in numerical approximations.
