Revision as of 12:24, 19 November 2010

Reading

Read sections in Munkres' textbook (Topology, 2nd edition). 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 sections , just to get a feel for the future.

Doing

Solve and submit the following problems from Munkres' book:

  • Problem 1 on page 199.
  • Problem 1 on page 205.
  • Problems 1, 4, 5, 8, 9 on pages 212-213.

Due date

This assignment is due at the end of class on Thursday, November 25, 2010.
