"WebbIn fact, examining this proof we see that equality holds in Cauchy-Schwarz iff the angle between x and y is a multiple of ˇ, or in other words, iff x is a rescaling of y. Thus, we can write the theorem in a stronger form: Theorem 1.3 (Cauchy-Schwarz, v2.0). Given x;y 2Rn, we have (xy)2 (xx)(y y) with equality if and only if x is a rescaling of y.
