                        <p>The vector space of all polynomials with finite degree has a basis, <m>B = \{1,x,x^2,x^3,\dots\}</m>, which is infinte.</p>

                        <p><m>P_n</m>, the vector space of polynomials with degree at most <m>n</m>, has dimension <m>n+1</m> by <xref ref="theorem-FTC"></xref>.  [Cross-reference is just a demo, content is not relevant.]  What happens if we relax the defintion and remove the parameter <m>n</m>?</p>
