The second formula is obtained by a more elementary method, see pages 175 to 180 in this book. This method uses only the trigonometric addition theorem and some clever guesses.\u003c\/p\u003e\u003cp\u003eThis book is a our through topics from number theory and modern algebra, including the Chinese remainder theorem, quadratic reciprocity and geometric construction of the regular 17, 257 and even the 65 537-gon, Galo is theory, and more. The book contains detailed proofs and many numerical examples with computer code.\u003c\/p\u003e","brand":"Atlantic Books","offers":[{"title":"Paperback","offer_id":46451207438487,"sku":"9781955070263","price":1826.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9781955070263.webp?v=1769136117","url":"https:\/\/atlanticbooks.com\/products\/number-theory-and-modern-algebra-a-personal-approach-9781955070263","provider":"Atlantic Books","version":"1.0","type":"link"}
