Assignments for Weeks 10 and 11

Remember that the rough draft of your second paper is due Monday, April 17. See posted policies for more details.

Reading

Read Chapters 5 and 6. Beware of a few misprints and foibles:

• Page 222 uses the concept of "defect", which is not defined until p. 252. (See the last exercise below.)
• Page 254, line ll: Angle C should be Angle C'. (In line 13, it really should be Angle C.)
• Page 260: The last paragraph of the proof of Prop. 6.6 seems to have migrated to the end of the next proof ("To prove symmetry ...", pp. 261-262).

Homework due Wednesday, April 12 (in Week 12)

1. Exercise 5.1, p. 228.
2. Exercise 5.7, p. 231. (W)
3. Exercise 6.6, p. 271-272.
4. Exercise 6.7, p. 272.
5. Exercise 6.10, p. 273.
6. Use Proposition 6.1 to justify the "defect" argument in Legendre's proof (end of first full paragraph on p. 222, "Therefore ... 2d").
