• Read sections 2.4, 3.1 and 3.2 in our textbook. Remember that reading math isn't like reading a novel! If you read a novel and miss a few details most likely you'll still understand the novel. 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 section 2.5, just to get a feel for the future.

• Solve problems 1, 2, 4 and 9 on pages 106-107, problems 1, 2 and 9 on pages 151-152 and problems 1, 2aceg, 2bdf, 7, 19 and 21 on pages 165-168 but submit only your solutions of the underlined problems. This assignment is due at the tutorials on Thursday November 16.
