Since there was no coverage last Friday, it doesn't make sense to include p.58 with HW2. So, I am officially removing p.58 from HW2. I'll put it into HW3 instead. ------------------------------------------- HW3 due: in class on Wed 22 Feb p.58 2.4a, 2.4b, 2.5a, 2.5b p.59 2.12, 2.15 p.61 2.30, 2.31 p.62 2.48a-2.48d p.64 2.56, 2.57, 2.59a-2.59f ------------------------------------------- HW4 due: in class on Wed 29 Feb p.83 3.7-3.11 ------------------------------------------- HW5 due: in class on Wed 7 Mar p.83 3.12, 3.13, 3.19, 3.20, 3.21 ------------------------------------------- NOTE: Term exam THROUGH HW5 on Wed Mar 14 ------------------------------------------- HW6 due: in class on Wed 4 Apr p.102 4.6, 4.10, 4.18, 4.19, 4.20 ------------------------------------------- HW7 due: in class on Wed 11 Apr p.103 4.38 ------------------------------------------- HW8 due: in class on Wed 18 Apr p.104 4.46 p.124 5.2, 5.3, 5.4 ------------------------------------------- HW9 due: in class on Fri 27 Apr p.124 5.10 Also, use contradiction to prove: Thm: If a and b are integers Then a^2-4b^2 is not 3 Hint: if it were, that would mean that a^2 is 3 (mod 4). Now check both the case where a is even and where a is odd. ------------------------------------------- HW10 due: in class on Wed 2 May p.150 6.4(1), 6.5, 6.6 ------------------------------------------- HW11 (EXTRA CREDIT) due: along with final p.214 9.15, 9.20 NOTE 1: For 9.15, state and prove both your claim about surjectivity (onto) and injectivity (1-1) NOTE 2: This is purely extra credit.
