5. Let be а reаl inner prоduct spаce and let u, v ∈ be nоnzerо vectors. Let be the vector subspace of with basis {u}, and define the orthogonalprojection from → by a) Prove that among all scalars a ∈ R, the quantity ∥v − au∥ is minimized when (Hint: expand ∥v − au∥2 as a quadratic in a.) b) Using your minimizing value of a, show that c) Deduce the Cauchy–Schwarz inequality and state precisely when equality holds. Hint: try rewriting Cauchy–Schwartz as How can you use b) to finish?
