25.14. Show that when h/o and and are each dependent on a Wiener processes, the ith component of the volatility of wis the ith component of the volatility of A minus the ith component of the volatility of g. Use this to prove the result that if is the volatility of U and is the volatility of V then the volatility of U/V is of +-200 Use the result in Footnote 7.) (
