Let set of prime numbers P 3have the inner product given by evaluation at minus3,minus1,1, and 3.Let p 0 (t )equals 4,p 1 (t )equals t, and q (t )equals StartFraction t squared minus 5 Over 4 EndFraction. Notice that these polynomials form an orthogonal set with this inner product. Find the best approximation to p (t )equals 2 t cubedby polynomials in Span StartSet p 0 comma p 1 comma q EndSet.
