Respected Sir,
I am Amit Maji, a phd student of IIT, in India. I am interested to watch the video lecture of linear Algebra. I could not able to see that. There is some error occurred.

I am very much interested to see those video lectures. Kindly please tell me how to download those videos. Thanking you.

yours' truly,
Amit Maji

Hi my name is Lungani Siobindi and I'm an engineering student at the University of Cape Town, South Africa...

I would like to express my umost gratitude MIT and to Prof. Gilbert Strang, thank you for taking the initiative of making world class education available to the world.

Hi nice lecture , very good efforts, there is another Indian website www.univexcellence.com giving expert faculty lectures for all grades ..... Do chk it as well. SAmples on youtube also .

Comment15 Li Tai Fang, April 8, 2011 at 5:52 a.m.:

I've been trying to learn linear algebra on my own...... tough to do. This makes it SO much easier!

Comment16 Venkatesh Umaashankar, May 25, 2011 at 3:38 p.m.:

Well explained, easy to follow. I enjoyed listening. Thanks a lot Professor. Strang

Comment17 Ozgur, May 29, 2011 at 10:58 p.m.:

The best sources of algebra and algebra help, algebra problems, algebra formulas, algebra calculators, algebra equations, pre algebra, algebra textbooks here.

Comment18 nimra, March 16, 2013 at 6:41 p.m.:

very informative

Comment20 ruben, June 7, 2015 at 6:59 a.m.:

There is a lot to be desired by this teaching style. The problem runs through his textbook as well. I end up feeling like I have to yell at the screen, Tell ME the Procedure alreade. Explain the THEORY. It sucks. And he has way too much prostylization. Enough. I'm not here to argue about differential equations. How about FOCUSING on the therum and definitions of the generalized arithmatic of matrixes. It is unfathomable that you can go through three classes in lectures without having the rules for Vector multiplication to be EXPLICITLY defined.

Jabber jabber jabber jabber. And then you still don't know what exactly he is talking about and you have to scamper to other textbooks to try to get insight.

BTW - the second video should be axed altoghter, the one placed in here from the other class. The TA's video is just completely useless without other background.
