Consider the following space of measurable functions defined on [0,1]: equipped with the norm "!1 # X = f : xf2(x)dx < ∞ 0 $! 1 %1/2 " f "X= 2xf2(x)dx . 0 a). Prove that X a Hilbert space and find the inner product which determines the above norm. b). Use the Gramm-Schmidt orthogonalization process on the set of functions f1(x) = 1, f2(x) = x, f3(x) = x2.
