To derive the basic formulas pertaining to a spherical triangle, we use plane trigonometry on planes related to the spherical triangle. For example, planes tangent to the sphere at one of the vertices of the triangle, and central planes containing one side of the triangle.

2020年8月19日 · Trigonometry, to which it is intended as a sequel; it contains all the propositions usually included under the head of Spherical Trigonometry, together with a large collection of examples for exercise.

SPHERICAL TRIGONOMETRY. CHAPTER I. 8. Spherical Trigonometry treats of the various relations between the sines, tangents, &c., of the known parts of a sphe¬ rical triangle, and those that are unknown; or, which is the same thing, it gives the relations between the parts of a solid angle formed by the inclination of three

Spherical Trigonometry 2 CESAR’s Booklet It’s the purpose of this booklet to deduce some formulae and equations that may come in handy when working with spherical trigonometry.

Let a spherical triangle be drawn on the surface of a sphere of radius , centered at a point , with vertices , , and . The vectors from the center of the sphere to the vertices are therefore given by , , and

To obtain the spherical law of cosines for angles, we may apply the preceding theorem to the polar triangle of the triangle 4ABC. This one has sides a0 = (ˇ A)R, b0 = (ˇ B)Rand c0 = (ˇ C)R and angles A0 = ˇ a=R, B0 = ˇ b=Rand C0 = ˇ c=R. The spherical law of cosines for the triangle 4A0B0C0 states
