Master trig with a classic guide to navigation and practical astronomy
Learn plane and spherical trigonometry, plus the stereographic projection of the sphere, with clear methods you can apply to real-world problems in navigation and surveying.
This edition presents a concise, student-friendly approach that blends theory with practical examples. It covers how trigonometry underpins navigation, geography, astronomy, and the mensuration of heights and distances, and it explains how to determine latitude, longitude, and other key positions using accessible rules and diagrams.
- Foundational theory paired with practical methods and step-by-step examples
- Rules and formulas for solving problems in navigation and maritime surveying
- Illustrations and worked problems showing how to apply trigonometry to real measurements
- A historical perspective on the development of logarithms, spherical trigonometry, and related topics
Ideal for students and professionals seeking a durable, examination-ready reference that connects geometric theory with everyday measurement and navigational calculations.
