Plane And Spherical Trigonometry

""Plane and Spherical Trigonometry"" by Elmer A. Lyman is a comprehensive textbook that covers the fundamental principles of trigonometry. The book is divided into two parts, the first of which covers plane trigonometry and the second of which covers spherical trigonometry. The first part of the book covers topics such as angles, triangles, functions, identities, and equations. It also delves into the applications of trigonometry in areas such as navigation, surveying, and engineering. The second part of the book covers spherical trigonometry, which deals with the study of triangles on the surface of a sphere. This section covers topics such as spherical triangles, spherical trigonometric functions, and the solution of spherical triangles.The book is written in a clear and concise manner, with numerous examples and exercises to aid in understanding. It is suitable for students of mathematics, physics, engineering, and other related fields. The book is also a useful reference for professionals who need to apply trigonometric principles in their work. Overall, ""Plane and Spherical Trigonometry"" is a valuable resource for anyone seeking to deepen their understanding of trigonometry.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
