chebtd() double chebtd ( unsigned int  n, double  x  ) Derivative of Chebyshev polynomial of first kind Tn'(x) Purpose chebtd computes the derivative of the Chebyshev polynomial of the first kind Tn'(x). Returns Derivative of Chebyshev polynomial of first kind Tn'(x). Parameters [in] n Argument n. (n >= 0) [in] x Argument x. Error handling Range error (ERANGE) may occur. Note If x < -1 or x > 1, this routine is much slower and recommended not to be used. Reference boost/math/special_functions
