Let V = R [ x ], the real vector space of polynomials with real coecients. We dene < f,g > = R 1-1 f ( x ) g ( x ) dx , the standard inner product on this space. (a) Find a scalar a such that < a,a > = 1. (b) Find scalars b and c such that < a,b + cx > = 0 and < b + cx,b + cx > = 1. (c) Find scalars , and such that < a, + x + x 2 > = < b + cx, + x + x 2 > = 0 and < + x + x 2 , + x + x 2 > = 1 . 1...
