PLANE AND SPHERICAL TRIGONOMETRY Introduction It is assumed in this chapter that readers are familiar with the usual elementary formulas encountered in introductory trigonometry. We start the chapter with a brief review of the solution of a plane triangle. Plane and Solid Geometry, to Which Is Added Plane and Spherical Trigonometry and Mensuration. by George Roberts Perkins.

The present work is constructed on the same plan as my treatise on Plane 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. In the course of the work reference is made. The Six Trigonometric Functions. 1. $\sin \theta = \dfrac{a}{c}$ 2. $\cos \theta = \dfrac{b}{c}$ 3. $\tan \theta = \dfrac{a}{b}$ 4. $\csc \theta = \dfrac{c}{a}$.
