This vintage work contains an elementary treatise on plane and spherical trigonometry, with information on its applications to navigation, surveying, heights and distances, and spherical astronomy. Written in clear, understandable language and full of helpful tables and diagrams, this vintage book, although old, contains much in the way of information that will be of considerable utility to the modern reader, making it both a great practical resource and a wonderful addition to collections of allied literature. The chapters of this book include: General Principles of Plane Trigonometry, Sines, Tangents, and Secants, Right Triangles, General Formulas, Values of the Sines, Cosines, Tangents, Cotangents, Secants, and Cosecants of certain Angles... and more. Many antiquarian books such as this are becoming increasingly rare and expensive, and it is with this in mind that this book is being republished now complete with a new, specially commissioned introduction on the subject.
