TATA57 Frequently asked questions

  • 2.13b) the denominator should read $(e^{\pi}+1)^2$.
  • I think there's a mistake in the answer to 3.7 (only in the Swedish exercise collection). There's a minus sign missing in front of the series.
  • A trigonometric polynomial where all components have periods $2\pi/k$ is it's own Fourier series (just expand using Euler's identities).
  • 6.2b) beware of the fact that there are problems at $z=\pm i$.
