Days of the course will be described as 1-M, 1-W, 1-F, 2-M, etc.
Due 1-F: Problems B-1, B-2, B-5, B-7.
(This means problems from the last section of Handout B. Future
assignments will have six to eight problems. Problems will
generally be a mixture of easier ones to build intuition and
harder ones to develop theory.)
