By now, we have covered most methods in proofs. Skim thru the chapter and check out the exercises: don’t think about which section they are from, but treat them as individual problems. Try to start the problems and see if you have a general idea for them.
Problems to turn in:
Section 3.5: 19, 20, 26, 27, 28, 30
Section 3.6: 1, 2
Section 4.2: 2
