Plane Trigonometry: A clear, practical introduction to the geometry of angles
This edition presents Webster Wells’s classic text from the Wells' Mathematical Series. It introduces plane trigonometry for students, with a focus on definitions, measurement of angles, and the fundamental trigonometric functions. The book emphasizes the circular method of angle measurement and shows how to convert between circular measure and degrees.

Two opening sections explain how angles are defined and measured, including degrees, minutes, seconds, and circular measure. Early chapters lay out the sine, cosine, tangent, and other ratios from right triangles, then expand to general properties, formulas, and the solution of right and oblique triangles. The work blends geometric reasoning with algebraic tools, and it presents numerous examples and solved problems.

What you’ll experience in this edition:
- Clear definitions and step‑by‑step development of the six principal trigonometric functions
- Explanations of circular and degree measures, with practical conversion rules
- Methods for solving right triangles and applying formulas to areas and triangles
- Worked examples, formulas for common tasks, and tables for reference
- Guidance on how to tailor the course for shorter study, if desired

Ideal for readers of high‑school through early college level who want a solid, traditional grounding in plane trigonometry and its applications. It is suitable for self‑study or classroom use, and for anyone seeking a historically solid treatment of the subject.

• Foundational definitions: angle measurement, circular measure, and basic trig ratios


• Rules and formulas for right and oblique triangles, including area calculations


• Progression from specific right-triangle results to general properties of triangles


• Practical examples and worked problems for mastery and reference

Ideal for readers of who want a traditional, self-contained approach to plane trigonometry.
