8. [10] Show that (B)t = t, t 13 0, in the following order: a. Let {1'1\"} be a sequence of partitions of [0, t] such that H\" = {t3 = 0,t'f,...,t;n = t} and the mesh of u goes to zero as it goes to innity; and let Viz) denote the quadratic variation of B corresponding to the partition H\". Write down the expression for V79. 1). Show that the LQ-norm of V3] t converges to zero as it goes to innity
