Question

let p(x) = a0+a1x+a2x2 and  q(x) = b0+b1x+b2x2

be vectors in P2 with inner product <p,q> = a0b0+a1b1+a2b2

Consider the polynomials in the set {−1+x2,2+x+x2}

Show that the polynomials in the set do not form an orthonormal set.

Use the Gram-Schmidt orthonormalization process to form an orthonormal set from these polynomials. Keep the order, and show work for the orthogonalization, then normalization.

Do the polynomials in the orthonormal set (from question 2) form a basis for P2 ? Why or why not?
