Lost netbook / fundamental theorem / homework / exams / rutabaga?

Hi everyone, 

Someone left a netbook and a pencil case behind in class yesterday and a student from the class that meets at 5:30 in our room gave it to me, so I have it with me in my office. If it’s yours come by my office to get it. I’ll ask you what brand it is and any distinguishing characteristics of it to validate your ownership of it. If you can’t make it today, send me an email. I’ll bring it to class tomorrow if necessary but I’d rather not because I am physically weak and carrying even a small computing device is very taxing on my underdeveloped body.

I’ve posted the Fundamental Theorem of Invertible Matrices in the Documents tab, so go on over there at your leisure and take a gander.

For problem 2 of Homework 10, you don’t have to do a proof by contradiction. In fact, there is a fairly simple direct proof.

I will post an assignment tomorrow, but it won’t be collected, so it’s not really a homework. More like a review sheet for your upcoming exam 3.

Exam 3 (which is Thursday May 8th) is mandatory. The final exam (that is, the exam on May 19th) will be optional. If you choose not to take it, your grade distribution will be the following: Exam 1: 24% / Exam 2: 28% / Exam 3: 28% / Best 9 homework grades: 20%

Please don’t ask me (neither now nor after the exam 3 grades are posted) what your letter grade will be based on your current grades. After the third exam grades are up, I will post the grade distribution, but I won’t know what the cutoffs will be for each letter grade until after the final exam is graded. 

If a kid asks where rain comes from, I think a cute thing to tell him is ‘God is crying.’ And if he asks why God is crying, another cute thing to tell him is ‘Probably because of something you did.'”
