I have to start from a simple 2nd order ordinary deifferential equation as:
y’’+2ξωny’+ω2y = F
The solution should be of the form
y = ∫F(Ω) G(t - Ω) dΩ (integral from 0-t)
where
G(t) = 1/ω * e^(-ξωnt)sin(ξt) for ξ<1
G(t) = e^(-ωnt) for ξ=1
G(t) = 1/ω * e^(-ξωnt)sinh(ξt) for ξ>1
and
ω = ωn√|1-ξ^2|
n in ωn is subscript.
Any help in this regard will be highly gratified.
Thanks in advance.
