  This paper is aimed at studying sensitivity of parameters \alpha and \beta
appearing in the operators introduced by D.D. Stancu [11] in 1969. Results are
established on the behavior the nodes used in Bernstein-Stancu polynomials and
the nodes used in Bernstein polynomials and graphical presentations of them are
generated. Alternate proof of uniform convergence of Bernstein-Stancu operators
and an upper bound estimation are derived. It is also established that the
parameters \alpha and \beta in Bernstein-Stancu polynomials can be used to get
better approximation at a point x = (\alpha)/(\beta) in [0,1] to the Bernstein
polynomials.
