The first compulsory exercise and tomorrow's exercise session

The first compulsory exercise can be found here. It builds on an exercise from chapter 2, which is also given for next week, and the deadline is 10. september. I urge everyone to use the friday exercise sessions to ask me about compulsory exercises, or other exercises you are stuck on. In the exercise session, I will let you work on our own on the exercises most of the time, but will also go through problems (which you suggest) on the blackboard. After each exercise session I will put publish the corresponding solution manuals. ?yvind
