Master the theory and practice of plane and spherical trigonometry with practical navigation tools.
This introductory treatise presents the core ideas of trigonometry alongside ready-to-use rules, formulas, and applications. It emphasizes how trigonometry underpins navigation, surveying, and the mensuration of heights and distances, making complex concepts approachable for learners.
This edition organizes the material to help both beginners and more advanced students. You’ll find three interconnected parts: a study of logarithms and tables, practical trigonometry with numerous worked examples, and the theory that ties it all together. The text balances geometric reasoning with algebraic methods to build a clear, usable toolkit for real-world problems.
- Learn the fundamentals of plane and spherical trigonometry
- Apply rules and formulas to measure distances, heights, and navigation problems
- Explore methods for determining latitude and other navigational quantities
- See the connections between theory and practical calculation through many examples
Ideal for readers of navigation, surveying, astronomy, and geography, as well as students seeking a solid, workmanlike introduction to these essential mathematical tools. This edition clarifies how theory supports practical work in the field and in the classroom.
