hi dimitris, sorry about that posting. here we go again: G(t)=6.06 - 4.17*Cos[(Pi*t)/84] + 1.19*Cos[(Pi*t)/42] - 2.95*Sin[(Pi*t)/84] + 0.71*Sin[(Pi*t)/42] p(t) = UnitStep[33.6 - t] so that the Laplace-transformed function that I'd like to invert, G(s)/ p(s) is G(s)/p(s) = (3.83*^7*E^(33.6*s)*(0.0029 - 0.049*s + s^2)*(0.0054 + 0.031*s + s^2))/ ((-1. + E^(33.6*s))*(Pi^2 + 1764.*s^2)*(Pi^2 + 7056.*s^2)) thanks! dan
