WebFind the value of the 500th-degree Chebyshev polynomial of the first kind at 1/3 and vpa (1/3). Floating-point evaluation is numerically stable. Now, find the symbolic polynomial T500 = chebyshevT (500, x) , and substitute x = vpa (1/3) into the result. This approach is numerically unstable. Approximate the polynomial coefficients by using vpa ... WebOct 7, 2024 · Next, we recall some properties of the monic orthogonal Chebyshev polynomials that we will need in the sequel. Let \(\{T_n\}_{n\ge 0}\) (resp. \(\{U_n\}_{n\ge 0}\)) be the monic Chebyshev polynomial sequence of the first (resp. second) kind. These polynomials can be given by
