The material is arranged in such a way that the first six chapters give the essentials of a course in numerical trigonometry and logarithmic computation. The remainder of the theory usually given in the longer courses is in the last two chapters.
Book 1 is pre-calculus trigonometry. We assume the student is relatively new to algebra and do algebra step by step. Many of the pages have closely related free/YouTube videos at the Khan Academy. Many students find the video presentation helpful.

This book is not just about mathematical content but is also about the process of learning and doing mathematics. The reader is expected to study the material in the book by working out examples rather than just reading about them.

The distinguishing features of this book are: a concise presentation of the fundamental part of plane trigonometry up to the solution of triangles; the use of five-place logarithms; a chapter on spherical trigonometry; a chapter on applications.
