F(u) = ∫∞ -∞ f(x) exp(-i2πux) dx = ∫∞ -∞ exp(-x^2) exp(-i2πux) dx = exp(-π^2 u^2)

When you find a good solution—one that includes not just the final equation but the assumptions, the coordinate transformations, the physical reasoning—treat it as a tutor, not a crutch. Re-derive it. Vary the inputs. Plot the results. Argue with it. In doing so, you will not merely solve Goodman’s problems; you will internalize Fourier optics itself. F(u) = ∫∞ -∞ f(x) exp(-i2πux) dx =
