2.
Let p(x) = 2+ x, q(x) = 3 + x², r(x) = 1+ 2x + 7x2 be three
vectors in P2, the vector space of polynomials of degree at most two. Consider
the ordered bases B [1, p, q] and S= [1, x, x²].
(a) Evaluate the coordinate vector of r with respect to B.
(b) Evaluate the change matrix from S to B.
Define T : P2 -→ P2, T(f(x)) =f(0) + f(1)x - f(x) for all f e P2. Let
A = MsB(T) be the matrix representation relative to B and S.
(c) Evaluate A and compute all the eigenvalues of A.
(d) Evaluate the eigenvalues of T and compute their algebraic and geometric
multiplicities. Is T diagonalizable? Explain your answer.
Endow the vector space P2 with the inner product
(f, 9) = | f(r}g(x) dæ
(f, 9 € P2).
(e) Show that the polynomials 1 and r are orthogonal to each other, and
find a polynomial h(x) so that {1, , h(x)} is an orthogonal basis for P2.
(f) Define S = {x+1,x²} (a set of two polynomials). Evaluate S-.
