In Complex Conics and Their Real Representation, Benjamin Ernest Mitchell surveys the historical development that links analysis and geometry. The book explains how imaginary quantities can be visualized and used to model real geometric figures, using ideas traced from Gauss, Cauchy, Poncelet, Chasles, and Von Staudt. It introduces the Laguerre–Study method as a powerful way to represent complex points with real picture planes, and it develops the concept of a real representation of complex points as pairs of real points. The text then builds toward canonical forms for complex circles and conics, and it shows how transformations and pencils of lines connect complex and real geometry.

Laguerre–Study representation and the idea of picture planes for complex points
How complex lines and circles relate to real geometric figures through transformations
The move from general equations to canonical forms for complex conics
Historical context showing the bridge between analysis and geometry

Ideal for readers of advanced geometry and the history of mathematics who want a rigorous, accessible look at how imaginary elements can be given real geometric form.

Store Description

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 visit 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.
