Hi Professor,

Just a bit confused about Example II, the question does not say take the limit as n goes to infinity, how could you just assume that? :):) Really nice video! Thank you very much!

Yea I meant A/(x-3)^2 + B/(x-3).

Thank You!

Thank you for the answer. I wouldn't worry about little mistakes here and there, if we can catch them it means we understood what was being done,ergo the class is very good. Thank you again.

Can Laplace transforms be used on differential equations not in the form given at the beginning of the video? Because for those equations I’d rather use the method of undetermined coefficients covered earlier. Thank you! Great videos!

sorry Dr Murry I know it is not your fault ,but I am not happy with educator tech team .though I asked for fixing this problem weeks ago, yet it has not fixed yet! this kind of delay since we should pay each month for these courses is not acceptable.

Thank you Dr. Murray. Perhaps it's an ipad issue or the network I was connected to at the time. I'll have to try it on a desktop.

Hi Dr. Murray, thank you for your lecture, you explain so well.  On the integral of finding E(Y1), your 1 looks like a 2, and I was confused until the end where you circled the number and said it was a, "one".

Never mind, I now see the minor error in the video. Thank you for the wonderful course, Professor!

Hi,Professor
At 10:48 you said -pi/4 is a positive term so we don't have to add pi to it, but it seems to me that -pi/4 is a negative term, wold you explain why?
Thank you
