Links Mathematical Techniques Home Index Spherical Trigonometry One of the primary concerns in astronomy throughout history was the positioning of the heavenly bodies, for which spherical trigonometry was required. The diagrams below show trihedrals, polyhedra with triangular sides. For astronomy, V is the position of the observer, and PQR are points on a sphere centred at V, the celestial sphere. From 2 dimensional trigonometric relations the upper diagram gives: From the right hand diagram, and the fact that PQR is perpendicular to VP, we can get: QR = PQ + PR - 2PQ PR cos A = VQ + VR - 2 VQ VR cos a Simplifying and applying Pythagoras' Theorem gives: + 2 PQ PR cos A Which can be simplified further, dividing by (VQ)(VR) using 2 dimensional trigonometrical relations to give the first law of cosines for trihedrals: Construction of a second trihedral called the polar trihedral from the first gives a different set of relationships between the quantities of the first law, the second law of cosines: These equations can be used to calculate positions on the celestial sphere, however, the laws can be simplified by consideration of the spherical triangle (see diagram below).

Trigonometry Contents Introduction Trigonometric Functions Solution of Triangles Circles and Areas ... References Introduction In this article I will review what we both know very well, as I recently have done, trying for utility as well as conciseness. For trigonometry to be fun, one should be prepared in geometry and algebra, at least in the properties of triangles, circles and parallels, and in the manipulation of algebraic formulas. This is not really much preparation, but it is essential. The trigonometry text itself introduced the student to logarithms, once the invariable accompaniment to trigonometry, but now much less important that electronic pocket calculators are available. In omitting logarithms in trigonometry, it should be kept in view that logarithms are very important in mathematics, and the proper and efficient use of tables is still a valuable skill. These subjects belong somewhere, even if not in trigonometry. Now, come review with me! Trigonometric Functions Trigonometric functions are also called circular functions because of their simple relation to various lengths defined by a radius of a circle making an angle with a reference direction, as shown in the figure at the right. This is not the only way of defining trigonometric functions; they can be defined as analytic functions of a complex variable z by power series, for example.
