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 ?
