1. Suppose V is the vector space of continuous functions f : [-1, 1] → R. (a) Show that (,): V × V → R given by (f,g) = [' , ƒ(x)g(x)(1 — x²) dæ defines an inner product. (b) Let p(x) = 1 and q(x) = x be elements of V. (i) Calculate the value of ||p|| (with respect to the given inner product). (ii) Calculate the value of ||q|| (with respect to the given inner product). (iii) Calculate the angle between p and q (with respect to the given inner product).
