Let be the vector subspace of consisting of all scalar multiples of the vector , and define the orthogonal projection from into by a) Determine the value of the real scalar that minimises the quantity . (Hint: expand as a quadratic in .) b) Using your minimizing value of , show that . c) Deduce the Cauchy–Schwarz inequality and state precisely when equality holds. (Hint: try rewriting Cauchy–Schwarz as .) How can you use b) to finish?
