Practical trigonometry for industry and engineering, with a hands-on, problem‑driven approach.

This volume presents technical trigonometry in a constructive format that ties concepts to real-world applications, using an emphasis on accurate, usable results.

The book focuses on core trigonometric ideas and their use in manufacturing, design, and measurement. It blends explanations with a daily work-book method, guiding readers through problems and exercises that reinforce clear thinking, precise calculation, and reliable results. A goal is to help students move from theory to practical skills they can apply in technical settings.

Step-by-step work-book approach that reinforces daily practice and written reasoning
Core topics including logarithms, right and oblique triangles, and the relation of trigonometric functions
Use of slide rules, scales, and reference tables to compute with precision
Problems and examples linked to manufacturing and technical applications

Ideal for readers of engineering, drafting, and technical trades who want a clear, usable foundation in practical trigonometry.
