Master the fundamentals of plane trigonometry with clear explanations and practical exercises.

Originally published as a comprehensive guide for students, this course covers the key ideas of plane trigonometry, from defining angles to applying trigonometric ratios. It introduces both the rectangular and circular (sexagesimal) measures of angles, and it progresses through identities, multiple-angle formulas, and the solution of triangles. The text also covers logarithms and the use of mathematical tables, along with a thorough treatment of circles and other figures tied to triangles.

Structured for study and reference, the book balances theory with worked examples and problems that reinforce understanding of the subject. It presents essential tools for solving real‑world problems involving angles, distances, and heights, as found in geometry, surveying, and related fields.

Foundational definitions of angles and units of measure
Trigonometrical ratios, identities, and formulas for sums, differences, and multiple angles
Techniques for solving triangles and calculating areas, circles, and related figures
Practical guidance on logarithms and using mathematical tables

Ideal for readers beginning with plane trigonometry or needing a solid reference as they study geometry and applications.
