### Extra Credit Information

• 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.
