Note: This post is part of my scientific computing course (UW AMATH481) in autumn 2016. The course web page is here.
In this lecture, we reviewed some of the facts from last lecture about Chebyshev nodes and Chebyshev polynomials and discussed the aliasing phenomenon in this context (recall that aliasing also occurs for Fourier modes on equispaced grids). The material corresponds to Chapters 2–4 of “Approximation Theory and Approximation Practice”, the first 6 chapters of which can be downloaded here.
