1. The problem statement, all variables and given/known data What is the laplace transform of e^(-t) cos 2t u(t-1) 2. Relevant equations definition of Laplace transform: LT of f(t) = integral of f(t)e^-st dt, where limits of integration are from 0 to infinity 3. The attempt at a solution since I have u(t-1) then do I just change the limits of integration to go from 1 to infinity instead? then I guess what is the fastest way to evaluate the resulting integral: integral of e^-(s+1)t cos 2t dt ?
