Master the foundations of plane trigonometry with a thorough, rigorous guide. This classic text presents the core ideas of trigonometric functions, their expansions, and their geometric and algebraic connections. Authored by E. W. Hobson and first published in the late 19th century, it offers a solid framework for students tackling real-angle problems, complex quantities, and the geometry of triangles.
The book is organized to build understanding step by step. It begins with measuring angles and the circular functions, then moves to the addition formulas, multiple-angle identities, and the relationships between trig and algebra. It also introduces complex numbers, logarithms, and the role of infinite series and products in trig theory, all framed for practical problem solving in geometry and trigonometry.
What you’ll experience:
- Clear development of sine, cosine, and their sums with straightforward proofs and geometric intuition
- Step-by-step exploration of the circular functions of several angles and their interrelations
- Practical treatment of the exponential theorem, logarithms, and complex quantities
- Numerous worked examples that connect theory to triangle problems and applications
Ideal for students and instructors seeking a reliable, historically grounded reference that emphasizes rigour and practical understanding. This edition provides a comprehensive roadmap from basics to advanced topics in plane trigonometry.

Paperback. Etat : New. Print on Demand. This book provides an expert-level overview of trigonometry. The author, a distinguished professor in pure mathematics, sets out a detailed theory of circular functions, applying these functions to geometrical situations and showing how they have been used to solve problems for centuries. The full story of their development is given here for the first time, with research-level material on the nature of the transcendental numbers Ï and e, usually inaccessible to students. The book will be of interest not only to students of mathematics, but to anyone who has ever wondered about the mathematical complexities behind the beauty of the natural world, from the shapes of flowers to the ebb and flow of tides.
