<< uh, all the prof did was show those notes on the projector and read them in his heavy accent and this material was covered in one hour last week so i didnt really have the whole quarter to learn it >>
In that case, look at Chapter 19 except 19.6, 19.7, 19.8, and Chapter 21 except 21.5, 21.6. These were covered in the last two weeks.
