Also solve the following problem:
Solve the unsteady vibrations of the membrane on a circular drum. The membrane displacement satisfies the wave equation
The boundary condition at the edge is For initial condition, assume that the membrane is struck at the point r=0.5 and . In other words assume that and that is a delta function at r=0.5 and , so that for any function .What frequencies will be present in the vibrations, and with what relative strength?
