Section 9.83 UnivariatePolynomial

The domain constructor UnivariatePolynomial (abbreviated UP) creates domains of univariate polynomials in a specified variable. For example, the domain UP(a1,POLY FRAC INT) provides polynomials in the single variable a1 whose coefficients are general polynomials with rational number coefficients. UP(x,INT) is the domain of polynomials in the single variable x with integer coefficients.
