Problems, and regarding next week

Next week there is lecture on Monday, but nothing on Tuesday. We'll discuss on Monday which of the below problems that should be assigned for the seminar Tuesday 28th.

Problems: 

• Here is a screendump of a couple of problems assigned for last year. The first of these is a "puzzle"-ish problems you should not spend too much time on, but you should definitely have a look at the last, shorter one.
• 1-05, 1-04, 1-07 and 1-08; 1-08 might be hard - if so, try 1-01 first. In 1-07, you need to know that "mutually orthogonal" means that the dot product of any two of these, is zero.

Also, Eric's notes for the two first seminar are uploaded.
