- A trigonometric polynomial can be considered a periodic function on the real line, with period some multiple of 2π, or as a function on the unit circle.
- For trigonometric interpolation, this function has to be a trigonometric polynomial, that is, a sum of sines and cosines of given periods.
- A trigonometric polynomial of degree N has a maximum of N roots in any open interval [ a, a + 2π) with a in R.
- For instance, rational interpolation is interpolation by rational function s, and trigonometric interpolation is interpolation by trigonometric polynomial s.
- This can be seen as a form of polynomial interpolation with harmonic base functions, see trigonometric interpolation and trigonometric polynomial.
