Hello Everyone, I am aware that there are couple other posts like this on Video Lectures. But I was wondering if anyone of you know where I can find video lectures for an introductory course in differential equations. If not, then non-video lecture notes following the book I am using (Differential Equations By Dennis G. Zill) will also suffice. I know about the MIT opencourseware and I have been following it.Are there any other ones? Please let me know. Thank you for your time.
