Note the change of venue -- we'll be meeting in the "Costa Coffee" on the corner of Gt Marlborough St and Ramilies St.
With this session we embark on Stillwell's second "pillar" of geometry, leaving Euclid and ancient Greece behind in favour of Rene Descartes and the seventeenth century. The reading will be Chapter 3, sections[masked] inclusive. As usual, we recommend doing as many of the exercises as you can.
The arrival of coordinates made it possible to apply more algebra to geometry. This is a powerful technique but it can be offputting, so if you have trouble with anything specific please do ask in the comments and we can suggest a web page or two that will help. Be aware that if you're struggling, someone else probably is as well, and remember there'll be plenty of time to work through difficulties on the night.
We'll stop short of section 3.5 since some members may find the appearance of trigonometry a bit alarming -- we can also look at some of this in the session to help ease the transition.
This is a reading group for John Stillwell's Four Pillars of Geometry. The book can be purchased here (Amazon link). If you'd like to preview it first, we found an electronic copy hosted here (you need to register).
