A Treatise on Spherical Trigonometry: With Applications to Spherical Geometry and Numerous Examples (Classic Reprint) - Softcover

Inhaltsangabe

Explore the fundamentals and methods of spherical trig with this classic reference. It presents clear definitions, essential theorems, and worked examples that connect theory to problems on the sphere.

The book covers the sphere, great and small circles, and the polar framework, then builds up to spherical triangles, their parts, and key relations. It continues with right- and oblique-angled triangles, including Napier’s rules and related analogies, and concludes with practical considerations for areas and polygonal figures on the sphere. The volume emphasizes both the underlying geometry and concrete computations you can apply to spherical geometry and related applications.

• Foundational definitions and properties of the sphere, circles, and poles


• Procedures for analyzing spherical triangles and their polar relationships


• Formulas for sines, cosines, and tangents of angles and sides, plus special cases


• Rules of Napier and methods for solving right-angled and oblique-angled triangles

Ideal for readers studying spherical geometry, trigonometry, or surveying who want a thorough, example‑driven reference.
