WebDec 15, 2005 · One of the integration methods is the first kind Chebyshev–Lobatto quadrature rule, denoted by ∫-1 1 f (x) 1-x 2 d x ≃ π n + 1 ∑ k = 1 n f cos (2 k-1) π 2 n + π 2 (n + 1) f (-1) + π 2 (n + 1) f (1). According to this rule, the precision degree of above formula is the highest, i.e. 2n + 1. Hence, it is not possible to increase the precision degree of … In numerical analysis, Chebyshev nodes are specific real algebraic numbers, namely the roots of the Chebyshev polynomials of the first kind. They are often used as nodes in polynomial interpolation because the resulting interpolation polynomial minimizes the effect of Runge's phenomenon.
