www.mathworks.com › help › symbolic
Chebyshev polynomials of the first kind are defined as Tn(x) = cos (n*arccos (x)). These polynomials satisfy the recursion formula Chebyshev polynomials of the first kind are orthogonal on the interval -1 ≤ x ≤ 1 with respect to the weight function . Chebyshev polynomials of the first kind are special cases of the Jacobi polynomials

Evaluate Chebyshev Polynomials with Floating-Point Numbers. Floating-point evaluation of Chebyshev polynomials by direct calls of chebyshevT is numerically stable. However, first computing the polynomial using a symbolic variable, and then substituting variable-precision values into this expression can be numerically unstable.
