In \u003ci\u003eTrigonometric Delights\u003c\/i\u003e, 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, \u003ci\u003eTrigonometric Delights \u003c\/i\u003eirrevocably changes how we see this essential mathematical discipline.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eBinding Type:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Princeton University Press\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 04\/07\/2020\u003cbr\u003e\u003cb\u003eISBN:\u003c\/b\u003e 9780691202198\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 256\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.50lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 8.30h x 5.50w x 0.60d","brand":"Eli Maor","offers":[{"title":"Default Title","offer_id":53514224763061,"sku":"9780691202198","price":15.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0473\/0804\/6492\/files\/9780691202198.jpg?v=1791903083","url":"https:\/\/pastforward.org\/products\/trigonometric-delights-9780691202198","provider":"Past Forward","version":"1.0","type":"link"}
