{ "item_title" : "Trigonometry", "item_author" : [" Casey Swanson "], "item_description" : "Trigonometry is a fundamental branch of mathematics that examines the relationships between the angles and sides of triangles. This study has given rise to trigonometric functions, which link the angles of a triangle to the lengths of its sides. The most prominent trigonometric functions--sine, cosine and tangent--are essential for analyzing triangles and modeling periodic phenomena. Trigonometry primarily focuses on planar right-angled triangles, which are two-dimensional shapes with one 90-degree angle. These principles are extended to triangles on spheres through spherical trigonometry. Trigonometric functions are widely applied across various fields, including optics, astronomy, medical imaging, cartography, economics, and seismology. The topics included in this book on trigonometry are of utmost significance and bound to provide incredible insights to readers. Also included is a detailed explanation of the various concepts and applications of the field. In this book, constant effort has been made to make the understanding of the difficult concepts of the subject as easy and informative as possible, for the readers.", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/9/79/888/836/9798888368459_b.jpg", "price_data" : { "retail_price" : "156.00", "online_price" : "156.00", "our_price" : "156.00", "club_price" : "156.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
