Synopsis

Master trig for plane and sphere with clear rules, formulas, and step-by-step methods for solving triangles.

This book provides a solid introduction to plane trigonometry and spherical trigonometry, including essential definitions, functions, and properties. It guides you through right and oblique triangles with worked examples and practical formulas.

You’ll find explanations of trigonometric functions, the relationships between angles and sides, and how to apply these tools to both flat and curved surfaces. The text also covers Napier’s rules for spherical triangles and methods to check your work using consistent sign conventions.

• Learn the core definitions of sine, cosine, tangent, and other trigonometric functions with practical guidance.
• Solve right and oblique triangles, plus introduction to spherical triangles and their special rules.
• Explore how Napier’s rules connect parts of a spherical triangle to the functions of its angles.
• Use check formulas and sign conventions to verify results and handle angles beyond 90 degrees.

Ideal for students seeking a reliable reference on plane and spherical trigonometry, as well as teachers and professionals who need clear, worked guidance.
