eval_chebys(n, x, out=None) = <ufunc 'eval_chebys'>¶
Evaluate Chebyshev polynomial of the second kind on [-2, 2] at a point.
These polynomials are defined as\[S_n(x) = U_n(x/2)\]
where \(U_n\) is a Chebyshev polynomial of the second kind.
Degree of the polynomial. If not an integer, the result is determined via the relation to
