Sep 11, 2008 - my god didnt know youtube was so useful, this really helps my degree cheers

Feb 13, 2009 - That's how it's usually done. It would be even more ridiculous to use random letters?

Oct 30, 2009 - makes me wish I was in MIT :(Its a dream....

Nov 21, 2009 - MIT is the best

Dec 22, 2009 - thank you very much. i found this very interestin--and furthermore i think this maybe will be important for me in the future

Jan 3, 2010 - this is a fantastic video, i have gone through my notes several times but not understood this concept. But now i do. Thank u for uploadingi wish my lecturer was good as this bloke

Jul 27, 2010 - Great teacher, but he made the the first half of this lecture (proof) unnecessarily complicated. There are much simpler methods of proving linearity, for example that presented by khanacademy here on youtube.

maniachris Says:

Dec 11, 2010 - I wish my maths course was nearly as good as this MIT course, my lecturer (if you can call him that) basically just reads out lecture notes written by another professor without explaining them.

Dec 23, 2010 - All the black box explanation is linear algebra for dummies

Feb 14, 2011 - This guy has amazing chalk abilities.

Mar 6, 2011 - does anyone know who this Simmons guy is and what book he wrote? it was in reference to a mathematician whose name was Abel? the prof said he had a tragic life and was a good read to be found in the Simmons book?

Mar 9, 2011 - awesome!

Jul 1, 2011 - what i cannot get is the point of the normalized solutions....plus at 37:00 y1 and y2 are e^it andd e^-it and not sin and cos... Sin and cos is waht you get as a general solution if you have initial conditions...

h0wud0in2 Says:

Jul 1, 2011 - and at the start the ODE is writen with the coeff. as functions of the independent variable (x say). I thought these had to be constants from the previus lecture

Oct 15, 2011 - great material!! congrats..

Jan 13, 2012 - after i watched this video Theory of General Second-order Linear Homogeneous ODE's: Superposition, Uniqueness, Wronskians., my insight is very open because the video is very good to give information

Jan 13, 2012 - I am very happy to see the vidoe from you, hopefully the others also are happy for You Theory of General Second-order Linear Homogeneous ODE's: Superposition, Uniqueness, Wronskians.

Pikanyaasan Says:

Feb 15, 2012 - I've been trying to solve the simplest 2nd order differential equations in my book all night and couldn't figure it out because my textbook makes no sense. This lecture helped me finally be able to solve them. Thank you!
