Here I have my PDE:
http://desmond.imageshack.us/Himg718/scaled.php?server=718&filename=pde.png&res=medium
I have found the solution by using the method of characteristics two times, one for x<0 and the other for x>0.
I have: U(x,y) = o for x<0 and U(x,y) = Uo(x-1)/(1+Uo*y) for x>0
The trouble I am having is finding the jump curve, x = [itex]\xi[/itex](y),
Im not sure if I am doing this correctly, but I keep getting the natural log of something, while my book says the correct answer is 1 - sqrt(1+Uo*y) for the jump curve...
can anyone help me?
much appreciated
