6) One of the most powerful inequalities in mathematics is the Cauchy-Bunyakovsky-Schwarz (CBS) inequality. It states: if u, u E R", then lü.히< 111||1| Further, equality is achieved only when ü and v are parallel, i.e. when u = cu for some constant c. Here are several problems that explore the power and scope of CBS. a) Suppose you want to maximize f(x, y, 2) = 8x + 4y +z subject to +y2 + z2 = 1. One way is...
