Elements Of Plane Trigonometry (1867)

Elements of Plane Trigonometry is a mathematical textbook written by James Hann and originally published in 1867. The book provides a comprehensive introduction to the principles and applications of plane trigonometry, which is the branch of mathematics that deals with the relationships between the sides and angles of triangles. The book is divided into several chapters, each of which covers a different aspect of plane trigonometry. The first chapter introduces the basic concepts of angles, degrees, and radians, and explains how to measure and convert between them. The following chapters cover topics such as the trigonometric functions (sine, cosine, tangent, etc.), the laws of sines and cosines, and the solution of triangles.Throughout the book, Hann provides numerous examples and exercises to help readers develop their understanding of the material. The book also includes several appendices that provide additional information on topics such as logarithms, spherical trigonometry, and the use of trigonometry in navigation.Overall, Elements of Plane Trigonometry is a valuable resource for students and professionals in the fields of mathematics, engineering, and physics, as well as anyone interested in learning more about this important branch of mathematics.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
