Laplace Transform for Cosine Function: Can You Obtain a Transfer Function?

Click For Summary
SUMMARY

The discussion centers on determining the Laplace transform of the equation d²y(t)/dt² = k⋅cos(Φ)⋅y(t) to obtain a transfer function. Participants suggest consulting Laplace transform tables to identify the appropriate transformation techniques. The equation involves a second-order differential equation where k and Φ are constants. The key takeaway is that the Laplace transform can be applied to this equation, enabling the derivation of a transfer function.

Hi Guys,

I have an equation I'm trying to work out if it 'Laplaceable'?
As in, can I get a transfer function?

d2y(t)/dt2 = k⋅cos(Φ)⋅y(t)
