n If f(x) = Σ a;x' is a polynomial in R[x], recall the derivative f'(x) is a polynomial as well i=0 (we'll talk more about the fact that derivatives are linear, in chapter 3). Recall I write R[x]n for the polynomials of degree < N. Let P(x) = aixº be degree N, N i=0 a.k.a. assume an # 0. Show that the derivatives P(x), P'(x), ...,P(N)(x) form a basis of R[x]n (where p(N) means the Nth derivative of P).

as Exercise P12.14. Write a class Polynomial that stores a polynomial such p(x) = 5x10 + 9x7-x-10 as a linked list of terms. A term contains the coefficient and the example, you would store p(x) as power of x. For (5,10),(9,7),(-1,1),(一10,0) Supply member functions to add, multiply, and print polynomials. Supply a com- structor that makes a polynomial from a single term. For example, the polynomia; can be constructed as Polynomial p(Term(-10, 0)); p.add (Polynomial(Term(-1, 1))); p.add (Polynomial(Term(9,...
