Problems and Theorems in Plane Trigonometry is a mathematical textbook originally published in 1840 by David Hewitt. The book is designed to help students develop their understanding of plane trigonometry, a branch of mathematics that deals with the relationships between the sides and angles of triangles. The book is divided into two main parts. The first part contains a series of problems that cover a wide range of topics in plane trigonometry, including basic concepts such as angles, triangles, and circles, as well as more advanced topics such as inverse trigonometric functions, logarithmic and exponential functions, and spherical trigonometry. Each problem is presented with clear explanations and detailed solutions, making it easy for students to follow along and learn from the examples.The second part of the book is devoted to theorems in plane trigonometry. These theorems are presented in a clear and concise manner, with detailed proofs and examples to help students understand the underlying concepts. The theorems cover a wide range of topics, including the law of sines and cosines, the Pythagorean theorem, and the double angle and half angle formulas.Overall, Problems and Theorems in Plane Trigonometry is an excellent resource for students studying mathematics, particularly those interested in trigonometry. The book is well-written and easy to understand, with clear explanations and detailed examples that make it an ideal reference for both students and teachers alike.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
