Master classic text on trigonometry and perspective that builds from Euclid to modern methods
This edition presents a practical tour of plane and spherical trigonometry, with the principles of perspective and the projection of the sphere. It blends historical context with methods learners can apply to problems in geometry, surveying, and drawing.
- Learn the foundations of trigonometry and how it connects to perspective and spherical figures
- See step-by-step approaches to constructing and interpreting projections and diagrams
- Explore examples and explanations that ease the move from plane to spherical geometry
- Understand how logarithms and other tools shaped modern trig tables and calculations
Ideal for readers of geometry and technical drawing, navigation, or architectural study who want a solid, practical grounding in these topics.
