Let P3 have the inner product given by evaluation at -3, -1, 1, and 3. Let p0(t)=1,p1(t)=t and p2(t)=t2 Required:a. Compute the orthogonal projection of p2 onto the subspace spanned by p0 and p1. b. Find a polynomial q that is orthogonal to p0 and p1, such that {p0,p1,q} is an orthogonal basis for Span {p0, p1,p2 }. Scale the polynomial q so that its vector of values at (-3, -1, 1, 3) is (1, -1, -1, 1).
