# scipy.special.c_roots¶

scipy.special.c_roots(n, mu=False)[source]

Computes the sample points and weights for Gauss-Chebyshev quadrature. The sample points are the roots of the n-th degree Chebyshev polynomial of the first kind, $$C_n(x)$$. These sample points and weights correctly integrate polynomials of degree $$2n - 1$$ or less over the interval $$[-2, 2]$$ with weight function $$f(x) = 1/\sqrt{1 - (x/2)^2}$$.
