Glen Van Brummelen tells the story of trigonometry as it evolved from an instrument for understanding the heavens to a practical tool, used in fields such as surveying and navigation. In Europe, China, and America, trigonometry aided and was itself transformed by concurrent mathematical revolutions, as well as the rise of science and technology.\u003c\/p\u003e\n\n\u003cp\u003eFollowing its uses in mid-sixteenth-century Europe as the 'foot of the ladder to the stars' and the mathematical helpmate of astronomy, trigonometry became a ubiquitous tool for modelling various phenomena, including animal populations and sound waves. In the late sixteenth century, trigonometry increasingly entered the physical world through the practical disciplines, and its societal reach expanded with the invention of logarithms. Calculus shifted mathematical reasoning from geometric to algebraic patterns of thought, and trigonometry's participation in this new mathematical analysis grew, encouraging such innovations as complex numbers and non-Euclidean geometry.\u003c\/p\u003e\n\n\u003cp\u003eMeanwhile in China, trigonometry was evolving rapidly too, sometimes merging with indigenous forms of knowledge, and with Western discoveries. In the nineteenth century, trigonometry became even more integral to science and industry as a fundamental part of the science and engineering toolbox, and a staple subject in high school classrooms.\u003c\/p\u003e\n\n\u003cp\u003eA masterful combination of scholarly rigour and compelling narrative, \u003ci\u003eThe Doctrine of Triangles\u003c\/i\u003e brings trigonometry's rich historical past full circle into the modern era.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"NewSouth Books","offers":[{"title":"Default Title","offer_id":46854930301164,"sku":"9780691179414","price":54.99,"currency_code":"NZD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0705\/7784\/8556\/files\/9780691179414.jpg?v=1759259670"},{"product_id":"heavenly-mathematics-by-glen-van-brummelen-9780691175997","title":"Heavenly Mathematics","description":"\u003cdiv class=\"book-description\"\u003e\n\u003cp\u003e\u003cem\u003eHeavenly Mathematics\u003c\/em\u003e traces the rich history of spherical trigonometry, revealing how the cultures of classical Greece, medieval Islam, and the modern West used this forgotten art to chart the heavens and the Earth.\u003c\/p\u003e\n\n\u003cp\u003eOnce at the heart of astronomy and ocean-going navigation for two millennia, the discipline was also a mainstay of mathematics education for centuries and taught widely until the 1950s.
