Paperback. Condizione: New. Print on Demand. This book provides an introduction to trigonometry, aiming to teach readers how to measure the sides and angles of triangles. It begins by establishing the relationship between the length of the triangle's sides to its angles, before introducing the concept of circular measure. There is a thorough explanation of trigonometrical ratios, including sine, cosine, tangent, cotangent, secant, and cosecant, as well as exploration of their values for certain angles. The book progresses onto the solution of right-angle triangles and the measurement of heights and distances. It concludes with the trigonometric ratios of the sum and difference of various angles. The book will appeal to anyone wanting to gain a foundational understanding of trigonometry for the first time.
