I'd like to know if there are any good online books, lecture notes, videos, tutorials, or similar that are free to the public (on differential equations). Suggestions are welcome!
$\begingroup$ I have converted the question to community wiki, as it's asking for a big list and there is no single right answer. $\endgroup$– Zev ChonolesSep 7, 2011 at 0:18

1$\begingroup$ @Matt: What's your background? Are you talking about ODE or PED, or both? More information may be helpful for people to answer you questions. $\endgroup$– user9464Sep 7, 2011 at 1:00
$\begingroup$ My background is computer science. I took a class on ODEs, but it's been awhile. I'd like to start with ODEs, but really anything is good at this point. $\endgroup$– Matt GroffSep 7, 2011 at 1:35
Paul's online notes has a section on Differential equations:
I have not personally read them, but the rest of his notes are helpful and easy to read.
well this one gives you a very huge collection to choose from
It requires you to be a registered member.
$\begingroup$ well was that meant as sarcasm? anyhow, i have rephrased my words. if my previous answer seemed off the track, sry $\endgroup$– BhargavSep 7, 2011 at 4:04
You could try my notes, which include ode and pde. There are also applets on my web page.
