1. The problem statement, all variables and given/known data
This has to do with the unit step function. The question is; Sketch the function g(t) = 1 for 0<t<1 and is 0 for t>1. Express g(t) in terms of the unit step function and hence or otherwise show that L(g(t)) = 1/s^2  e^s (1/s^2 + 1/2) 2. Relevant equations 3. The attempt at a solution I sketched the graph (see attachment below). Im guessing the unit step function is t(u(t)  u(t1)). I tried one way of getting that answer like this t( u(t1) u(t+1)  u(t1) ). Obviously it didnt work out. I think I need to get u(t) in the form u(ta) so I can use the table of Laplace transforms and just read out of it. How do I manipulate this kind of functions? Thanks.
