For those who have griffiths its problem 3.41 (its not exactly the same but that's what this question is modeled after) Alright so I was going through how to solve a problem in my textbook when I got stuck midway through. The approach I had taken wasn't working and I wasn't quite sure where...

Does anyone know of a good website which explains the method to solving PDE's of this form. I still can't see a way to solve it (I tried to replace u with x and that doesn't work) and I'm really worried about finishing. Thanks to anyone who replies.

could I please get a hand with this. I still don't know where to go from the above.

I have a PDE problem set due on monday and as I look at the teacher's method for solving this problem it doesn't make any sense to me. I'll show what I have so far. Find the solution of U^2U_x + U_y = 0 that satisfies u(x,0)=x So I started out with the characteristic equations...

It did. :) I originally had the whole solution where my post was but I figured I would take it down after I had asked my professor about it and she said it was the right approach.

EDIT: I talked with my professor a bit about this as well and she said I had the right idea. Thanks a lot for the help. :)

well the question I have is about black bodies and it says that we have one black body (nonreflecting) at temperature Tu and another black body at temperature T1 (they are parallel and in a vacuum.) The energy flux between them is (Tu^4 - T1^4)*Stefan-Boltzmann's constant and the question wants...

EDIT: I figured out the rest of the question just by going over what you said again. It really helped out a lot.
