Find the Fourier Transforms

f_{1}(t) = [itex]\frac{2}{3-it}[/itex]

f_{2}(t) = [itex]\frac{2}{3-it}[/itex]cos(t)

2. Relevant equations

F{H(t)e^{t}} = [itex]\frac{-1}{-1-it}[/itex]

F{f(t)cos([itex]\omega[/itex]t)} = [itex]\frac{1}{2}[/itex][F([itex]\omega[/itex]+[itex]\omega[/itex]_{0}+F([itex]\omega[/itex]-[itex]\omega[/itex]_{0})]

3. The attempt at a solution

For the first question, my answer was 4*pi*H(-[itex]\omega[/itex])e^{3[itex]\omega[/itex]}from using the first eqaution F{H(t)e^{t}} = [itex]\frac{-1}{-1-it}[/itex] and using symmetry

From there, I don't know how I would use the second equation to answer the second question.
