I have now put up a new set of exercises, "Exercises 5", on the webpage. Some of the exercises are things I conveniently "left as exercises" during the lectures. If you are busy working on the assignment, it is no problem postponing looking at these new problems for a week or two, but it may be useful to have seen and thought about these things before we start talking about Chapter V in a few weeks time.
