About this title

Synopsis

Master spherical trigonometry with clear rules, step-by-step methods, and concrete examples.

This college- and school-friendly text presents Napier’s rules for spherical triangles, explains key theorems, and shows how to apply them to solve right and oblique triangles. The book emphasizes careful procedure, sign handling, and cross-checks to ensure correct results.

This edition guides readers through the full workflow of spherical trigonometry, from fundamental concepts to practical calculations. You’ll learn how to identify the middle part in a triangle, apply the rules to find unknowns, and verify results with checks. The material includes worked examples, discussion of logarithmic work, and careful attention to special cases and quadrant signs. It is written to support self-study as well as classroom use.

Foundational concepts: middle parts, opposite and adjacent parts, and Napier’s rules
Theorems that constrain spherical right triangles and relationships among angles and sides
Systematic methods for solving right and oblique triangles, with multiple given parts
Worked examples and step-by-step logarithmic calculations to reinforce learning

Ideal for readers studying higher geometry, trigonometry, surveying, or related fields who want a solid, practice-focused reference on spherical and plane trigonometry in one volume.

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. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? 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. If this is your first purchase with us, or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
