WitrynaThis is a discussion on how to use the Napier's rules and theorems on right spherical triangles WitrynaApplying the cosine rule in the solution of a spherical triangle. To revise spherical trigonometry click here. As explained in the link above, we amend the cosine rule when we are working with spherical triangles. For example, to find side a in the spherical triangle shown in the diagram below we have: Cos(a) = [Cos(b) . Cos(c)] +[Sin(b) .
