Algorithms for Periodic Functions, the transforms are sped up by about a factor of two by exploiting symmetries in the data and the coefficients. The chapter ends with how to approximate the derivatives of periodic functions, thus presenting the fundamental algorithms that are needed to solve partial differential equations with periodic boundary conditions.

Survey of Spectral ApproximationsThe methods developed are the Fourier collocation and Galerkin methods, polynomial collocation and Galerkin methods, and nodal continuous and discontinuous Galerkin methods. At the end of the chapter, after it is clear what the methods are, how they are derived, and how they are implemented, a discussion is presented on how to choose between them.
