About this title

Synopsis

Discover the roots of trigonometry and logarithms in this historical treatise.

This edition presents plane and spherical trigonometry alongside the construction and application of logarithms, laying out foundational definitions, theorems, and methods for solving triangles.

In clear, student-friendly language, the work introduces key concepts such as the circle’s degrees, minutes, and seconds; chords and tangents; and the idea of a trigonometrical canon. It also explains how logarithms simplify calculations by turning multiplication into addition, and includes early approaches to hyperbolic logarithms and their use in determining powers and roots.
What you’ll encounter:

Foundational definitions of plane trigonometry and basic circle data (degrees, arc measures, and common terms like chords, tangents, and secants).
Early theorems linking sides, angles, and radii in right triangles, with practical methods for angle and side calculation.
A practical introduction to logarithms, including the construction and properties of indices and the idea of a canonical table.
Discussion of different forms of logarithms, including the hyperbolic variant, and methods to compute them.

Ideal for readers of historical mathematics, early geometry, and the development of trigonometric techniques. This edition is suited to students seeking a window into how early mathematicians presented and applied these essential tools.

Store Description

**Please note our transit times are from the date of dispatch.** We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places.

This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence.
