Lecture 4

It went fine for the first 40 minutes until I realized that I had only 10 minutes left to do one big proof. So of course I rushed through the big proof, making a fool out of myself. I think I write smaller on the board in this room, probably because I didn't want to make that squeaky noise... Anyway, this is it for all the things I know, now onto teaching things that I don't know...

Lots of people showed up in the office hours. It is a hard assignment, I guess. And, as one student said, it is at a much higher level than the first linear algebra course. Also, asking engineers to do proofs is a tough task.

Hopefully this will be the last bad lecture for the term. Not looking good for it, though.
