About this title

Synopsis

A clear, practical guide to plane trigonometry and spherical projections

This edition presents the definitions, key theorems, and useful constructions that form the core of plane trigonometry. It explains how to determine the rest of a triangle from three parts, uses circles and radii to connect angles with sines, tangents, and secants, and introduces a robust canon for computing these relationships. The text also covers foundational ideas for spherical projections, including methods to draw great circles and relate angles between circles to their poles and intersections.

This edition is organized to support study in school and self-guided learning, with step-by-step demonstrations and worked examples that illustrate the geometric reasoning behind trigonometric rules. It emphasizes the link between geometric figures and trigonometric quantities, making the material accessible to readers building a foundation in mathematics.

Core concepts: plane trigonometry definitions, sine, cosine, tangent, secant, and their relationships
Theorems and corollaries that connect triangle geometry to trig functions
Practical constructions and problems in spherical projections, including poles, great circles, and angle measurements
Historical context and structured explanations that aid comprehension and retention

Ideal for students, educators, and anyone seeking a solid, readable introduction to early trigonometry and its geometric applications.

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.
