The numerical example in Mondays's exercises made one of the answers too difficult. I have posted the exercises with revised numbers.

If you did not do the exercises in preparation for the seminar, I shall give you one more chance: hand your answers in to me on Thursday next. (24). On paper please, as you need to practice drawing diagrams on paper.

If there are difficulties, please mail me to make an appointment.
