Math 308 homework

Something useful to notice (again):

Most of the material for a given homework assignment is covered in class by the Monday before it's due, if not even earlier. And if you don't wait until Wednesday night (or later) to get started then you have a lot more time to ask questions about the assignment.

Something else useful to notice:

Your textbook has answers to the odd-numbered exercises that don't ask for definitions or proofs. The homework mostly consists of even-numbered exercises, but there are often very similar odd-numbered exercises around them.

Homework assignments

All assignments are due in class on the given date.

Due Jan. 23.
- Read sections 0 and 1 of the textbook. (Of course you should actually read every section of the book as it's covered in class. But especially these early sections contain some background material which will be assumed known and not all covered in lecture, so be sure to read them right away.)
- Section 0: 12, 32, 36.
- Section 1: 18, 22, 36, 38.
Note: just like last semester, you need to explain all your answers even when the problem doesn't explicitly ask for a proof.
