1. The Fourier series expansion of the function f(x) = |x| for -1 < x < 1 with f(x+2) = f(x) is given as the sum of cosine terms with coefficients an = -4/(nπ)2 for odd n. 2. The Fourier transform of f(x) = k for 0 < x < b is ik(e-iαb - 1)/α. The Fourier transform of f(x) = sinπx for |x| < 1 is 2πsinα/α2. 3. The Fourier transform of 3xe-9x2 is -iπe-α2/36 - 2α/
