Master plane and spherical trigonometry with practical problems and plates.
This new edition presents the essential definitions and the arithmetic of sines, then moves through plane and spherical trigonometry with worked examples and useful applications. It is designed for mathematical students and readers interested in practical surveying, astronomy, and navigation.
In a clear, student-friendly format, the book covers the fundamental concepts, subsidiary angles, and the methods for solving right and oblique triangles. It also explains how to apply trigonometry to real-world tasks, from measuring heights and distances to calculating areas and distances on curved surfaces. Plates are included to illustrate the procedures and results.
What you’ll experience
- A solid foundation in angle, trigonometrical lines, and their ranges
- Step-by-step solutions for plane and spherical triangles
- Practical problems in astronomy, dialling, and surveying using trigonometrical methods
- Explanations of how to use the tables and logarithms for calculations
Ideal for readers of historical mathematical texts, students beginning trigonometry, and professionals who rely on the geometry of the sphere and plane in their work.
