Yes, it is δ(t). The one is very similar to the previous one. After taking Laplace transform in t, this one will become the previous one. If I use the method pointed by other people, I have hard time to convert back (inverse Laplace transform) to time domain. That's why I ask the question...
Hi:
I have the following PDE:
ytzz=yzzzz+delta(t)
With I.C.: t=0, y=0; and B.C.s: z=0, y=0,yzz=0; z=-x,y=0,yz=0
Can someone show me how to solve it?

Hi:
Thank you for response. If I want to use Fourier transform to solve this one, how can I find the boundary conditons for y''(-h)? I need to use inverse Laplace transform to convert the y function. Therefore, it will become much easier to use the Fourier transforms.

Hi:
I try to solve this PDE as below:
y''''-ky''+1=0
With boundary conditions of x=0.y=y''=0 and x=-h,y=y'=0.
k and h are constant.
The solution look like from the Fourier transforms.
There is one term in the solution which is :
beta_n is the...
