Exercises and sections for Th. 26. Sep

Go to Nils' Lecture Notes and Exercises and do Ex. 6, 7, 8, 9,10, 11, 12, 13. We have done some of these exercises in class, and some of them are covered by previous exercises. 

In the lecture we'll finish up Chapter 5.5 from C&B, and if time allows, start Chapter 7.
