Homework
First Term:
Second Term:
- Homework 8: due 01/13/12
- Homework 9: due 01/23/12
- The originally posted version had a missing factor of i in Eq (2).
- As a result of this (and the late posting) no penalty will be applied for homeworks turned in by Monday 1/23.
- Homework 10: due 01/27/12
- Homework 11: due 02/03/12
- No homework due 02/10/12
- Homework 12: due 02/17/12
- Homework 13: due 02/24/12
- Note: This homework has been updated. The original version had 2 significant typos -- [i] some missing *'s (r where there should have been r*) in Eqs. (7) and
(8), and [ii] a spurious factor of 2 in the denominator of Eq. (8). If you've already printed the homework please see the new version.
- Homework 14: due 03/02/12
- Homework 15: due 03/09/12
