But if you miss a few details in a math text, often you'll miss everything that follows. So reading math takes reading and rereading and rerereading and a lot of thought about what you've read. Also, preread sections 2.4 and 2.5, just to get a feel for the future.
  • Solve problems 1, 2, 5, 13, 17 and 18 on pages 74-76, problems 1, 5a, 5b, 5c-g, 9, 15 and 16 on pages 84-86 and problems 1, 2, 3a and 3b on pages 96-97, but submit only your solutions of the underlined problems. This assignment is due at the tutorials on Thursday November 9.
