1. The problem statement, all variables and given/known data 2. Relevant equations Laplace Trasformations 3. The attempt at a solution a. done b. f(t)= t -3*t*u(t-1) + 4*u(t-1) -3*u(t-2) -2*t*(t-2) c. 1/(s^2) - (3e^-s -2e^-2s)/(s^3) + (4e^-s -3e^-2s)/s d. 1/(s-1) * (1/(s^2) - (3e^-s -2e^-2s)/(s^3) + (4e^-s -3e^-2s)/s) These are the answers i got but my friend got all different ones and we are not sure who is correct. Thanks for any help.
