Geometry I

• Syllabus (last revised on 09/08/09)

Professor Joel Roberts, who has taught this course multiple times, has posted a good explanation of how our approach to Geometry will be somewhat different than other courses. Please read it during the first week of the class.

Office Hours: Tuesday 11:30-1:30, Friday 11:00-12:00 in Vincent 4.

• Opportunity #1: Jeff Weeks will give a public lecture at 7:00pm in 125 Willey Hall on the West Bank on Thursday, 11/12/2009; see this postcard for more details. If you attend, send me a brief email describing the talk for 5 extra credit homework points. Alternatively, you can watch the lecture online in the IMA Video Library; click on "Math Matters Public Lectures."
• Opportunity #2: Hand in a complete solution to the following problem by 12/4/09 for five extra credit points: Find and prove the formula for the area of a spherical n-gon. Also solve the formula for the sum of the angles. Here's a brief overview of spherical geometry for those who missed the relevant material on 11/25. Note that some of the lunes in the "Area of a Lune" section on page 3 seem to be half-lunes, which is confusing. You might prefer this page for finding the area of a lune.

I record your numeric scores, not letter grades, but to give you an idea of how you're doing in the class I post approximate gradelines here. If the A line is 40, that means 40 is the lowest score in the A range, so it's the lowest A-. 39 would be the highest B+ in that situation.
