1. The problem statement, all variables and given/known data g(t) = (t+1)us(t) - (t-1)us(t-1) - 2us(t-1) - (t - 2)us(t-2) + (t-3)us)(t - 3) + us(t-3) 2. Relevant equations unit step function us(t-3) is same as u3 (t) Shift in time: L[f(t - T)us(t-T)] = e-TsF(s) us(t) ↔ 1/s t ⇔ 1/s2 3. The attempt at a solution 1/s2 + 1/s - e-s/s2 + e-s/s - 2e-s/s - e-2s/s2 + 2e-2s/s + e-3s/s2 - 3e-3s/s + e-3s/s 1/s(1 - e-s +2e-2s - 2e-3s) + 1/ s2(1 - e-s - e-2s + e-3s) My professor gave us a different answer online. It seems correct online. Any advice would be great thank you.
