Speaking of the world cup...
This thread was inspired by the World Cup 2006 thread. So, a little background first: I have a very vague idea of how football is played, in the sense that I know what the overrall goal is and mostly know what the rules are. Yet, I am very interested in getting into...
Another thing is, you can easily solve the problem using separation of variables, but saltydo's method seems fairly straightforward as well, but you must be careful with what you are integrating over what limits.

Ok, this is what even and odd extensions mean: Even extensions are symmetric over the y-axis, while odd extensions are symmetric over the origin. I don't have a way to show you how those work, but you can plot a few functions from say 0<x<1, and extend then in an even or odd manner.

Hi, I can help you write your paper, but I don't have yahoo messenger. Why not post your topic here, and I can suggest a few things. Also, if you can post the details of the specifics of the paper, that would be good too.

Ok, here is the deal.
You use the d'Alembert's formula when you are given a wave equation, but your domain is the entire real line. You use separation of variables if your domain is bounded, say from 0 to L.
Now, I am a bit confused about your problem. I can help you figure it out, but...
I have been there a few times, and I wasnt really all that impressed. First time I went though, we put in our name at around 4pm (this wasnt even a weekend), and we didnt get our table until 8pm. We were done eating by about 9:30 pm. Granted, I went with a bunch of my friends when I was in high...
Actually, you could have used the equation is suggested. The commutator [H,L] is zero, and <dl/dt> is obviously zero. Its a nifty little formula, and its very useful.

Hi, I am undergraduate at UIUC. If you are looking at a place in midwest, UIUC is a very good choice. If you can get in, then its easy to catch up on the coursework, since there are many grad students here who take undergraduate classes to prepare for the QUAL exam. UIUC is a huge dept, with...
Ok, so if x(pi -x) is your IC, then you will have to integrals to do. xpi* sin(nx)
and x^2 sin (nx). Its a bit more involved than the last one.
