# numpy.polynomial.chebyshev.chebweight

polynomial.chebyshev.chebweight(x)

  The weight function of the Chebyshev polynomials.

  The weight function is \(1/\sqrt{1 - x^2}\) and the interval of integration is \([-1, 1]\). The Chebyshev polynomials are orthogonal, but not normalized, with respect to this weight function.

  Parameters:
    x array_like

      Values at which the weight function will be computed.

  Returns:
    w ndarray

      The weight function at x.

  Notes

  New in version 1.7.0.
