WebbUse Cauchy Schwarz on euclidean space R³ (usual inner product) to show that, given estrictly positive real numbers a1, a2, a3, the inequality holds Related Topics Algebra Mathematics Formal science Science WebbThe Cauchy-Schwarz Inequality (also called Cauchy’s Inequality, the Cauchy-Bunyakovsky-Schwarz Inequality and Schwarz’s Inequality) is useful for bounding expected values that are difficult to calculate. It allows you to split E [X 1, X 2] into an upper bound with two parts, one for each random variable (Mukhopadhyay, 2000, p.149). The formula is:
