Questions and Answers

What is a Fourier series?

  • An expansion of a non-periodic function into a sum of trigonometric functions (correct)
  • A sum of polynomials
  • A series of exponential functions
  • A series of rational functions

    • Why are trigonometric functions used in Fourier series?

  • Because they are well understood (correct)
  • Because they are easy to differentiate
  • Because they are always convergent
  • Because they have simple integration rules

    • Can Fourier series be used to approximate all functions?

  • No, only for smooth functions
  • Yes, for all periodic functions
  • Yes, for all types of functions
  • No, because most functions have infinitely many terms in their Fourier series (correct)
