ux(x,t)+k[tanh(x)]ut(x,t)=0;
u(x,0)=u0(x);
I solved the equation by the method of characteristics and found x(t)=sinh-1(ektsinhx0) and so the solution is u(x,t)=u0{sinh-1[e-ktsihnx]}.
Now my real hustle is the following(Typed exactly as the lecturer asked it):
What you really want to see is how a ‘solitary’ initial state such as
u0(x)={ a0x2(1-x)2 for 0<=x<=1
{ 0 for x>1
will deform as time goes on.Remember that it will not deform at all if c is constant.
Do this by well-known methods and produce some video frames. You will have to
perform some elementary numerical calculations for which the code should be set
out in an appendix.
Please help me,
