But the Chebyshev polynomials, especially in their recursive definition, are a stroke of genius.
- bumby 9mo ago> How the hell does a polynomial "wiggle"? I believe they’re defining “wiggle” as just the slope/rate of change/derivative
- madcaptenor 9mo agoExactly. Wiggling feels more like a second-derivative thing to me but that's discussed too - Chebyshev polynomials max out the second derivative as well as the first.
