**1. find the inverse fourier transform of f(w)=e**

^{-i5w}sinc(2w)**2. I set up the integral to be from defn of sinc: 1/2pi*integral from -infinity to infinity (sin(2w)/2w)*e^-5w**

**3. i have no idea how to solve this integral, is there a better way to do this?**

i know that rect(t) has a F.T. of sinc(w/2) but how do i go the other way if it's 2w, not w/2?
