Solve the initial value problem

 \frac{\partial u}{\partial t} +\frac{u}{r} +\frac {\partial u}{\partial r} =0
 u(x,0)=0


Computer the Numerical solution at t=100,200,300 and 400.Use a domain of [5,450].The boundary condition at r=5 is u(5,t)= sin(:\omega t ).Perform computation for a) :\omega =\frac{\pi}{4} b) :\omega =\frac{\pi}{3}


Exact Solution

 u(x,0)=0.5 e^{-(ln 2) (\frac{x -t }{3}) ^2 }
