Question:
Find the Laplace transforms of tcos(at) and t^2cos(at). Do this without using the integral definition of the Laplace transform by starting with the transform of cos(at).
So this is what I did:
The transform of cos(at) is:
So taking the negative derivative of that with respect to s will give the Laplace transform for tcos(at), correct?
I got
Then taking the negative derivative of that shoul then give the transform for t^2cos(at).
Doing that I got:
Can anyone verify these answers or tell me where I went wrong? Thanks
