Hey alphabeta89.

It's been a while since I did DE's, but have you heard of the Lipschitz condition for the existence of a solution for a particular DE? - November 3rd 2012, 05:41 AMalphabeta89Re: Show that the initial value problem has a solution on R.
Nope, how do I go about doing it? :D

I haven't watched the video myself, but you might want to look at this:

Ok, so which domain of t and x do I apply on?

Well you have a positive period of L so you can think about the circle going from 0 to 2pi and the other object going from 0 to L.
