(a) Show that the Fourier transform of f1(t) is 1/iω(1 - e-2iω).

(b) By using the multiplicative property of Fourier transforms, or otherwise, show that the Fourier transform of f2(t) is 1/ω2(e-2iω(2iω + 1) -1).

(c) Hence, or otherwise, show that the Fourier transform of the function

is F(ω) = 2/ω2(3ωsin2ω - 2sin2ω).

(d) By using (c), evaluate -∞(2sin2x-3xsin2x)/x2 dx.
