Navigate with confidence using a practical guide to plane and spherical trigonometry and their applications to navigation and nautical astronomy.
This edition offers a clear path from fundamental trig to real-world sailing techniques. It combines theory with hands-on methods, showing how to compute courses, distances, and differences of longitude with established tables and procedures. The text emphasizes practical tools like Mercator sailing, middle-latitude corrections, and meridional parts, making complex concepts accessible for navigators and students.
- Concrete methods for plotting ship courses and estimating distances using plane and spherical trigonometry.
- Step-by-step treatment of middle-latitude sailing, including necessary corrections and tables.
- Explanation of Mercator’s approach and the use of meridional parts for practical calculations.
- Illustrative examples and notes that connect theory to navigation and nautical astronomy.
Ideal for readers of navigation, nautical science, and applied mathematics who want a hands-on reference that ties trigonometry to seafaring practice.
