Trigonometric Delights

<p><b>A fun entertaining exploration of the ideas and people behind the growth of trigonometry</b> <p/>Trigonometry has a reputation as a dry difficult branch of mathematics a glorified form of geometry complicated by tedious computation. In <i>Trigonometric Delights</i> Eli Maor dispels this view. Rejecting the usual descriptions of sine cosine and their trigonometric relatives he brings the subject to life in a compelling blend of history biography and mathematics. From the proto-trigonometry of the Egyptian pyramid builders and the first true trigonometry developed by Greek astronomers to the epicycles and hypocycles of the toy Spirograph Maor presents both a survey of the main elements of trigonometry and a unique account of its vital contribution to science and social growth. A tapestry of stories curiosities insights and illustrations <i>Trigonometric Delights </i>irrevocably changes how we see this essential mathematical discipline.</p>
