原題目:In the s-domain, via Laplace transform, one has 1 s s Y(s) = -------- + -------------- - ----------- e^(-πs) s^2+16 (s^2+16)^2 (s^2+16)^2 If this Y(s) is used to describe a 2nd-order Ordinary Differential Equation : y”(t) + p(t)y’(t) + q(t)y(t) = r(t) , with the initial conditions : y(0)=0 and y’(0)=1 , find p(t), q(t) and r(t) , respectively.               已經將 Y(s) → y(t)了,好像…沒什麼幫助?還是出發點錯了? 肯請大家賜教。 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 123.193.112.252
