I have a few questions that I'm not sure how to go about doing? This is what I was asked:

Use the table of transforms, linearity, and s-shifting to find F(s) = L (f(t)) for each of the following functions. Write the result as a rational function P(s)/Q(s).

1) f(t) = −4 + e^(−t)

2) f(t) = e^(4t) − 10 + sin t

3) f(t) = cos(2t − 5) (Hint: use the identity cos x ± y = cos x cos y ∓ sin x sin y.)

4) f(t) = e^(−2t) sin(3t)

How do I use the table of transforms, linearity, and s-shifting (if necessary) to find f(t) = L^−1 (F(s)) for these? F(s) = (1/(s + 1) + (3/ s^2 + 4)) F(s) = ((s + 3)/(s^2 + 3s + 2)) For the second one I was given a hint to find the partial fraction decomposition first.
