  We construct multiple representations relative to different bases of the
generalized Tschebyscheff polynomials of second kind. We build the
change-of-basis matrices between the generalized Tschebyscheff of the second
kind polynomial basis and Bernstein polynomial basis. Also, we provide an
explicit closed from of The generalized Polynomials of degree r less than or
equal n in terms of the Bernstein basis of fixed degree n.
