Various messages in re today/tomorrow/...

Seminar problems:

• The first bullet item: " take a stand on whether you by the" Wednesday 3rd lecture. (As mentioned, making updates to the schedule is a risk, and that particular detail is not worth it. But next week I might have to ...)
• Problem 37 has a question on the inverse, that requires tomorrow's lecture.
• Problem 139 (b): it will hopefully be clearer after tomorrow's lecture why this is the thing to do, but solving the equation system by Gaussian elimination should be doable by now.

(Before) tomorrow's lecture:

• I'd appreciate if you could browse the first four problems in the most recent set in Canvas, to see if "it makes sense".
• We will do:
  • more Gaussian elimination examples (I doubt if that long problem 2 will be covered though),
  • then say a little bit about the inverse as a concept; one way of calculating it involves the determinant, so:
  • determinants will be introduced.
• Material to be posted:
  • I hope to have a preview note out by tonight (read: tomorrow morning). Wednesday -> Auditorium 7, write on the notes -> less calculations typeset.
  • I have bugfixed the PDF: here. After tomorrow's lecture, I may or may not update it with annotations on what was actually covered. 

See you tomorrow. Nils
