Re: question on Final
You can use u(x,0)=eta(x) as data for 0<=x<=5 and u(0,t) = g(t) for t>0.
The solution will have a discontinuity along the characteristic coming from
x=t=0, but a very small one, since the two agree to about 0.0025.
If you want to make it even smoother, you can change g(t) to
g(t) = exp(-150(t-0.4)^2).
Then the jump is about 4e-11.
