http://math.ucla.edu/~robjohn/math/spheretrig.pdf 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 … See more 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 See more 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. … See more An analogous statement begins by taking α, β, γ, δ to be the areas of the four faces of a tetrahedron. Denote the dihedral angles by $${\displaystyle {\widehat {\beta \gamma }}}$$ etc. … See more The theorem is used in triangulation, for solving a triangle or circle, i.e., to find (see Figure 3): • the … See more Using the distance formula Consider a triangle with sides of length a, b, c, where θ is the measurement of the angle opposite the side of length c. This triangle can be … See more 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 See more Versions similar to the law of cosines for the Euclidean plane also hold on a unit sphere and in a hyperbolic plane.
