scipy.special.sh_chebyu(n, monic=False)[source]#

Shifted Chebyshev polynomial of the second kind.

Defined as \(U^*_n(x) = U_n(2x - 1)\) for \(U_n\) the nth Chebyshev polynomial of the second kind.

Parameters:

nint

Degree of the polynomial.

monicbool, optional

If True, scale the leading coefficient to be 1. Default is_False_.

Returns:

Uorthopoly1d

Shifted Chebyshev polynomial of the second kind.

Notes

The polynomials \(U^*_n\) are orthogonal over \([0, 1]\)with weight function \((x - x^2)^{1/2}\).
