Eli Maor teaches the history of mathematics at Loyola University in Chicago. He is the author of To Infinity and Beyond , e: The Story of a Number , Venus in Transit , and The Pythagorean Theorem: A 4,000-Year History .
Maor's presentation of the historical development of the concepts and results deepens one's appreciation of them, and his discussion of the personalities involved and their politics and religions puts a human face on the subject. His exposition of mathematical arguments is thorough and remarkably easy to understand. There is a lot of material here that teachers can use to keep their students awake and interested. In short, Trigonometric Delights should be required reading for everyone who teaches trigonometry and can be highly recommended for anyone who uses it. --George H. Swift, American Mathematics Monthly [Maor] writes enthusiastically and engagingly... Delightful reading from cover to cover. Trigonometric Delights is a welcome addition. --Sean Bradley, MAA Online Maor clearly has a great love of trigonometry, formulas and all, and his enthusiasm shines through... If you always wanted to know where trigonometry came from, and what it?s good for, you?ll find plenty here to enlighten you. --Ian Stewart, New Scientist This book will appeal to a general audience interested in the history of mathematics. I highly recommend [it] to teachers who would like to ground their lessons in the sort of mathematical investigations that were undertaken throughout history. --Richard S. Kitchen, Mathematics Teacher
