Let A be a symmetric positive definite nn matrix. Show that A can be factored into a product QQT , where Q is an nn matrix whose columns are mutually orthogonal. [Hint: See Corollary 6.4.7.]

L16 - 10 ex. In a chemical reaction involving materials A and B resulting in product C, A and B are reactants and C is the product.T e concentration of reactant A in moles per liter is denoted [ A]. Since concentration varies during reaction, [A], [B], and [eucisfi . Average rate of reaction on 1t 2i ]s ∆[C] [C](t2)...
