These identities approximate the sine rule of plane trigonometry when the sides are much smaller than the radius of the sphere. Derivation of the cosine rule Main page: Spherical law of cosines
In spherical trigonometry, the law of cosines (also called the cosine rule for sides ) is a theorem relating the sides and angles of spherical triangles, analogous to the ordinary law of cosines from plane trigonometry. Given a unit sphere, a "spherical triangle" on the surface of the sphere is defined by the great … Zobraziť viac First proof Let u, v, and w denote the unit vectors from the center of the sphere to those corners of the triangle. The angles and distances do not change if the coordinate system is rotated, so we … Zobraziť viac The first and second spherical laws of cosines can be rearranged to put the sides (a, b, c) and angles (A, B, C) on opposite sides of the equations: Zobraziť viac • Half-side formula • Hyperbolic law of cosines • Solution of triangles Zobraziť viac For small spherical triangles, i.e. for small a, b, and c, the spherical law of cosines is approximately the same as the ordinary planar law of cosines, Zobraziť viac 1. ^ W.
