1. The problem statement, all variables and given/known data The problem is not getting the answer to the laplace transform but instead reducing my answer so i dnt lose marks. If i work out the laplace transform of: L(t^3 * sinh(4t)) to be 3!/(2(s- 4)^4)- 3!/(s(s+ 4)^4) then how do i add these to get a single fraction? Its doing my head in 3. The attempt at a solution I know something has to be multiplied but i have no idea what it is... Thanks in advance!
