Augustus De Morgan
Trigonometry and Double Algebra is a book written by Augustus De Morgan, a prominent British mathematician and logician. The book is a comprehensive guide to trigonometry and double algebra, which is a branch of mathematics that deals with complex numbers and their operations.The book is divided into two parts. The first part covers trigonometry, which is the study of the relationships between the sides and angles of triangles. De Morgan provides a detailed explanation of the basic concepts of trigonometry, such as sine, cosine, tangent, and cotangent. He also discusses the properties of triangles, including the Pythagorean theorem and the law of sines and cosines.The second part of the book focuses on double algebra, which is the study of complex numbers and their operations. De Morgan explains the properties of complex numbers, including their addition, subtraction, multiplication, and division. He also covers the polar representation of complex numbers and the use of complex numbers in solving equations.Overall, Trigonometry and Double Algebra is a valuable resource for students and professionals in mathematics, engineering, and physics. The book provides a clear and concise explanation of complex mathematical concepts and their applications, making it an essential reference for anyone interested in these subjects.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
