Lecture cancelled! (And new problems)

Dear all,

My daughter is sick, so I'm afraid I have to cancel today's (Wednesday) lecture.

I have uploaded a solution to problem set 6 as well as a new problem sheet. It contains several problems where you have to use the method of characteristics, and some of them are quite hard. Try to do as many of these as you can!

See you tomorrow.

Best,
Ulrik
