Hint:
L 1 [ 1 ( s 2 + ω 2 ) 2 ] = 1 2 ω 3 ( sin ω t ω t cos ω t )
Note: ω is a real constant in this generalization.
Now, can you find the Laplace transform of sin ω t and ω t cos ω t to understand what is going on with one of the shift theorems and why this is the result?
Of course you can always use the formal definitions to find this also if that is the approach required.

I was toying with equations of the type f(x+α)=f(x) where f is a real function. For example if α=π2 then the solutions include the function fλ,μ(x)=λcos(x+μ). Are there more solutions?
On the other hand, if I want to solve the equation for any α, I can assume a solution of the form f(x)=eλx, and find λ as a complex number that enables me to solve the equation...
I was wondering: is the set of the solutions of dimension 2 because the derivative operator creates one dimension and the operator ϕ:f(x)f(x+1) adds another one? Is there some litterature about this kind of equations?

Explain how 0 e x x d x diverges? This is because the Laplace transform of 1 t can be reduced to this integral which has to diverge. But the limit comparison test with e x shows that the integral converges.
