A Treatise Of Plane Trigonometry, And The Mensuration Of Heights And Distances To Which Is Prefixed A Summary View Of The Nature And Use Of Logarithms (1855)

""A Treatise of Plane Trigonometry, and the Mensuration of Heights and Distances to Which is Prefixed a Summary View of the Nature and Use of Logarithms"" is a mathematical textbook written by Jeremiah Day and first published in 1855. The book focuses on the study of plane trigonometry, which is the branch of mathematics that deals with the relationships between the sides and angles of triangles, and the measurement of heights and distances using trigonometric functions. The book begins with an introduction to logarithms, which are mathematical tools used to simplify complex calculations. The author provides a summary view of the nature and use of logarithms before delving into the main topic of plane trigonometry. The book covers a wide range of topics in plane trigonometry, including the six trigonometric functions (sine, cosine, tangent, cosecant, secant, and cotangent), the properties of triangles, and the laws of sines and cosines. The author also discusses the use of trigonometry in measuring heights and distances, including the use of the angle of elevation and the angle of depression. Throughout the book, the author provides numerous examples and exercises to help readers understand the concepts and apply them to real-world situations. The book is written in a clear and concise style, making it accessible to students and professionals alike. Overall, ""A Treatise of Plane Trigonometry, and the Mensuration of Heights and Distances to Which is Prefixed a Summary View of the Nature and Use of Logarithms"" is a valuable resource for anyone studying or working in the field of mathematics.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
