Extracted text: Let po, P1, and p, be the orthogonal polynomials described below, where the inner product on P, is given by evaluation at - 2, - 1, 0, 1, and 2. Find the orthogonal projection of 213 onto Span{pn.P1.P2). Po (t) = 1 P, (1) = 3t P2 (t) = 12 -2 The orthogonal projection of 2t3 onto Span{po.P1.P2} is | (Simplify your answer.)
