Today:

• I am so confused

  will it ever end?

  (the answer is "Yes!").

• We're going to put off section 4.9 (Newton's method) until the last week of classes (which was reserved for "additional stuff").

• Distribute Section 4.10 Worksheet

• Return tests (remember that you can redo the test, and I'll average the scores. No need to redo problems which you did correctly. Hand in your "redos" and the original exam by Wednesday. Do not do your redos on the original test!)

  Here's a link to the Adobe pdf file version of the test.
