## Welcome to Linear Algebra, Spring 2017!

This page will contain handouts and documents related to our class MA405-002.

(1) Here is our syllabus.

(2) This is a video dating back to 70's. On one side I think it is boring, on the other side I thing it is awesome for 1976.
I am sure as the online generation, you can find better videos. Shoot me an email with a link if you have a cool linear algebra video.

(3) OK. I am not that old, here is a more recent one.

(4) 01/17/17, here is your first homework . As I said at the first lecture, we will not collect nor grade your homework.
I suggest you finish this one in one week from today for your own practice.

(5) You can access the course webwork page here . I assigned one homework for the addition of vectors.

(6) Thanks to Yuhan a typo in the HW1 is fixed and the file is updated.

(7) 01/25/17. Here is your second homework . Solutions to first homework will uploaded today evening.

(8) Solutions to Homework 1 is posted here .

(12) The list of suggested projects is here . We will talk about this in class today, do not bombard me with emails yet, please.

(13) While I was leaving the class today, Will asked about a proof of the fact that row reduced echelon form of a matrix is unique.
I usually prefer a combinatorial proof over induction but I think this one is nice enough to be satisfactory :)

(14) I don't think I will have time to prove the theorem we stated at the end of the Wednesday lecture.

I kindly ask you to read it from the book linear algebra done wrong at pg 47.

(15) Here is the solutions for HW4.

(16) 02/20/17 HW 5 is posted. I will try to upload solutions this Friday.

(17) 02/24/15 (Partial) Solutions to HW5 is here .

(18) 02/27/15 We have learned many concepts and theorems in last two weeks. To have a good intuition about these facts and objects, you have to have some experience with them.

For this purpose, I have assigned several homework on the webwork system which are all numerical computations. Please finish them before the end of spring break.

(19) 02/27/17 I decided that the way I phrased the second question of the quiz was not the best way to phrase it. So, everybody is going to get full credit from the second question.

The solutions of the quiz can be found here .
