Laplace Transform of unit step function HELP!!! 1. The problem statement, all variables and given/known data f(t)= e^t on 0<=t<1 . . . . t on 1<=t<2 . . . . sin(t) on 2<=t<infinity 2. Relevant equations Unit Step Function 3. The attempt at a solution Here is my attempt at a solution... f(t)=e^t*u(t)-e^t*u(t-1)+t*u(t-1)-t*u(t-2)+sin(t)*(t-2) Now I know I need to transform this equation, but I'm not sure how to break it up into something a little easier to comprehend. Any help would be greatly appreciated!!! Thanks in advance!
