Here are the homework assignments I have addounced in class.
The statement of record which actually defines the assigment is
whatever I announce in class, so be sure to attend every day or
get an update from someone present if you have to be away.

1. Due Friday, September 5 (at the start of class):
  section 1.1: 1b, 4b, 5b, 6, 8b, 17, 22
  section 1.2: 1b, 2, 3, 4, 7, 10, 14, 23

2. Due Friday, Sept 12
  section 1.4: 1k, 1l, 6, 14
  section 1.5: 1b, 1c, 2a, 4a-b-d-e-i-j, 5, 7, 9, 10, 12, 17
  section 2.1: 1a, 1b.

3. Due Friday, Sept 19
  section 2.1: 1c, 1e, 2, 4, 6, 10
  section 2.2: 2d, 4a, 12
  I would also like you to go back to section 1.4 and try 13a,b,c
    now that you're getting a little better with proofs :-)

4. Due Friday, Sept 26
   section 2.3: 2, 7, 8(1,b,c), 18, 21
   section 2.4: 1, 3(a,b), 4(a,b), 6, 11, 12

5. Due Friday, Oct 3
   section 5.1: 1(a,b,c,g), 7, 8
   section 3.1 14, 15, 16, 17

PLEASE NOTE; EXAM 1 will be Monday, Oct 6

6. Due Wednesday, Oct 15
   section 3.2 2a, 2d, 2f, 4, 7
   section 3.3 9, 14, 16
   section 3.4 1a, 2b, 3g, 5a, 5b

7. Due Monday, Oct 27
  section 3.3: 8, 13
  section 3.4: 11, 15, 19
  section 4.1: 3, 4, 7, 8
  Special exercise. Let the sequence a_n be defined recursively by a_1=a_2=1,
    and a_n=a_{n-1}+2a_{n-2}.  Compute the first 10 entries in the sequence by hand.
    Then, give a closed form expression for a_n; that is, write a formula for a_n
    which doesn't reference prior a_i's. This will parallel the Fibonacci sequence
    example from class. Make sure to check that your formula works on the first ten entires!

PLEASE NOTE: EXAM 2 will be Monday, Nov 3. I will try to get this HW back before then.
