Elements of Plane and Spherical Trigonometry: With Their Applications to Heights and Distances, Projections of the Sphere, Dialling, Astronomy, the Solution of Equations, and Geodesic Operations (Clas

Elements of Plane and Spherical Trigonometry offers a compact, analytic approach to the fundamentals of plane and spherical trigonometry and their practical uses.

This edition presents a clear path from core concepts to the methods that solve real problems in heights, distances, and geodesy, with applications to astronomy, dialling, and projections of the sphere.

This work emphasizes unity of method and aims to balance concise theory with practical calculation. It guides the reader through plane and spherical cases, develops logarithmic and differential techniques, and shows how these ideas apply to measurements and navigational problems.

• Analytic development of plane and spherical trig, with a focus on clear, repeatable procedures
• Applications to determining heights, distances, and geographic projections
• Methodical treatment of dialling, astronomy, and related geometric problems
• Structured progression suitable for students building a solid foundation in mathematics

Ideal for readers of classical mathematics, surveying, astronomy, and related fields who seek a compact, method-driven introduction to trigonaometry and its applications.
