Asymptotic Limit of Continuous Dual Hahn Polynomial
  Using Darboux method, we obtain an asymptotic limit for Continuous Dual Hahn Polynomial.The basic concept is to construct a comparison function which is the singular part of the generating function; then expand the comparison function. With little simplification and modification,the asymptotic limit is achieved.
