Using Green's formula, show that:
$${\cal F}\left[\frac{d^2f}{dx^2}\right]= -w^2F(w) + \frac{e^{iwx}}{2\pi}\left(\frac{df}{dx} - iwf\right) \\(evaluated\ from\ -\infty\ to\ \infty)$$
last part is supposed to be evaluated from minus infiniti to plus infinity for the $e^{iwx}$ portion
So I tried to integrate out ${\cal F}\left[\frac{d^2f}{dx^2}\right]$ and I was getting close, but not close enough...
