About this title

Synopsis

Unlock the foundations of trigonometry and its real-world uses in navigation, surveying, and astronomy.
This early 19th‑century treatise covers plain and spherical triangles, angles, and the core rules that link sides and angles to shape the world.
Practical guidance for fields like surveying and fortification, including how to measure distances, determine altitudes, and apply spherical geometry to mapmaking and travel.

The work is organized to teach definitions, theorems, and methods in a clear, step‑by‑step way. It blends theory with hands‑on problems, from calculating triangle properties to plotting hour lines and navigating with nautical and land-based instruments.

Definitions and measurements of plain and spherical triangles
Techniques for solving right- and oblique-angled triangles
Applications to navigation, fortifications, and mapping
Illustrative methods for using instruments like the theodolite and sextant

Ideal for readers of historical mathematics, surveying enthusiasts, and anyone curious about how early trigonometry guided exploration and engineering.

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.

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.
