A Treatise Of Trigonometry

A Treatise of Trigonometry: Plane and Spherical, Theoretical and Practical is a book written by Samuel Heynes and published in 1716. The book is a comprehensive guide to trigonometry, covering both plane and spherical trigonometry. It provides a theoretical foundation for the subject as well as practical applications, making it a valuable resource for students and professionals alike.The book begins with an introduction to the principles of trigonometry, including the definitions of angles, the trigonometric functions, and the use of logarithms. It then goes on to cover plane trigonometry, including the solution of triangles, the use of trigonometric tables, and the calculation of trigonometric identities.The second part of the book focuses on spherical trigonometry, which is the study of triangles on the surface of a sphere. This section includes the solution of spherical triangles, the use of spherical trigonometric tables, and the calculation of spherical trigonometric identities.Throughout the book, Heynes provides numerous examples and exercises to help readers understand the concepts and apply them to real-world problems. The book also includes a number of tables and diagrams to aid in calculations and visualizations.Overall, A Treatise of Trigonometry: Plane and Spherical, Theoretical and Practical is a valuable resource for anyone studying or working in the field of trigonometry. Its comprehensive coverage of both plane and spherical trigonometry, along with its practical applications, make it a timeless reference for students and professionals alike.In Which The Several Cases Of Plane And Spherical Triangles Are Solved, Instrumentally And Arithmetically.
