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 21 onto Span(po.P1 P2). Po (t) = 1 P, (1) = 3t P2(0) = ? -2 The orthogonal projection of 21 onto Span{Po.P1.P2} is. (Simplify your answer.)
