Let C[a, b] denotc the set of continuous functions f : [a, b] → R. Given any two functions S,9 € C[a, b], let (S, 9) = | S()g(t)dt. S(1)g(t)dt. Prove that the above bilincar form is bilincar, symmetric and positive (that is, (f, f) > 0 for all f € C[a, b]). You do not have to prove that this bilincar form is definite (that is, if (S, S) = 0, then f = 0).

Let C[a, b] denotc the set of continuous functions f : [a, b] → R. Given any two functions
S,9 € C[a, b], let
(S, 9) = | S()g(t)dt.
S(1)g(t)dt.
Prove that the above bilincar form is bilincar, symmetric and positive (that is, (f, f) > 0
for all f € C[a, b]). You do not have to prove that this bilincar form is definite (that is, if
(S, S) = 0, then f = 0).
