1. The problem statement, all variables and given/known data I am trying to work out the inverse Laplace transform of t^2*u(t-a). 2. Relevant equations 3. The attempt at a solution I have been old that it starts (t-a)^2*u(t-a)..... which I understand is substituting for (t-a). But I cannot seem to work out the rest can someone please help or explain. This isn't homework or coursework just a problem the lecturer failed to explain properly.
