It was eventually discovered, based on numerical results, that the first and fourth kinds perform better than the second and third kinds. While further comparison revealed that the second kind did better than the third kind.enChebyshev PolynomialsCanonical PolynomialsRecursive FormulationTau ApproximantResearch Subject Categories::MATHEMATICSArticle
