{"product_id":"9780486154640","title":"Introductory Non-Euclidean Geometry","description":"This fine and versatile introduction to non-Euclidean geometry is appropriate for both high-school and college classes. Its first two-thirds requires just a familiarity with plane and solid geometry and trigonometry, and calculus is employed only in the final part. It begins with the theorems common to Euclidean and non-Euclidean geometry, and then it addresses the specific differences that constitute elliptic and hyperbolic geometry. Major topics include hyperbolic geometry, single elliptic geometry, and analytic non-Euclidean geometry. 1901 edition.","brand":"Dover Publications","offers":[{"title":"Default Title","offer_id":47112138096880,"sku":"9780486154640","price":8.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780486154640_p0.jpg?v=1763737609","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780486154640","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
