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.

Example operations on univariate polynomials

\begin{axiom}
(p,q) : UP(x,INT)
p := (3*x-1)**2 * (2*x + 8)
q := (1 - 6*x + 9*x**2)**2
p**2 + p*q

      Perhaps you should use "@" to indicate the required return type, 
      or "$" to specify which version of the function you need.
