I need the time domain response of this system as a unit RAMP input C(s) = ((2s²) + 20s) / ((s²) + 4s + 20) I get that the RAMP input is C(s) = A/s² G(s) And now I think I need to simplify it so I can get it into a form that's on the Laplace Transformation table but this is what I'm having trouble with, I've tried manipulating it, but the 2s² on the top seems to be causing me an issue. The exponentially decaying cosine wave on the table seems to look the closest after manipulation, but when I have sketched it out, it doesn't cut the y axis at 1. I think it's my manipulation that's the problem. Any ideas? Cheers.
