WebThe theorem is trivially true if f is itself a polynomial of degree ≤ n. We assume not, and so dn > 0. Step 1 Suppose that f, pn has an alternating set of length n + 2. By Theorem 4, we have f − pn ≤ dn. As dn ≤ f − pn by the definition of dn, it follows that pn is a polynomial of best approximation to f.
