Trigonometric Delights

Trigonometry has always been the black sheep of mathematics. It has a reputation as a dry and difficult subject, a glorified form of geometry complicated by tedious computation. In this book, Eli Maor draws on his remarkable talents as a guide to the world of numbers to dispel that view. Rejecting the usual arid descriptions of sine, cosine, and their trigonometric relatives, he brings the subject to life in a compelling blend of history, biography, and mathematics. He presents both a survey of the main elements of trigonometry and a unique account of its vital contribution to science and social development. Woven together in a tapestry of entertaining stories, scientific curiosities, and educational insights, this book more than lives up to the title "Trigonometric Delights". Maor, whose previous books have demystified the concept of infinity and the unusual number 'e', begins by examining the 'proto-trigonometry' of the Egyptian pyramid builders.He shows how Greek astronomers developed the first true trigonometry.
