5) Let S = {1, 02, 03, 04} be an orthonormal set of functions on −1 ≤ x ≤ 1 using the usual inner products for functions. Suppose that functions f and g are given by f(x) = a11(x) + α202(x) + α303(x) + α404(x), g(x) = b₁₁(x) + b22(x) + b303(x) +b404(x). a) Show that (f, g) = a1b1 + a2b2+ a3b3 + a4b4. b) What does the result from a) remind you of?
