Solve the 2D non-homogeneous wave equation assuming that the boundary condition on the space is that for over the square boundary of the 2D surface. Also the condition on the time dependent part is . The wave has a sinusoidal source of a certain frequency given as . Make a graph and animation of the solution.
I solved the homogeneous part using variation of parameters.I don't know how to solve the inhomogeneous part .Do we have to use fourier trick to solve it.
