# Laplace transform

what is the Laplace transform of sin2(t-1)U(t-1)
(U is the unit step function)

i got 2e-s/s2 + 4
is this correct?
i'm unsure about the exponential part

Yup, that's right. I'm assuming you actually meant

$$\frac{2e^{-s}}{s^2+4}$$

as opposed to

$$\frac{2e^{-s}}{s^2}+4$$

which is what you actually wrote.
