Spectral methods use ___________

Spectral methods use ___________ Correct Answer Fourier series

Finite Difference methods use Taylor series. In spectral methods, spatial derivatives are evaluated using the Fourier series or one of their generalization. The simplest spectral methods deal with periodic functions specified by their values at a uniformly spaced set of points.
