2. Show that for Brownian Motion, we have: \(\forall t,\ n \geq 1\) integer. (1) \(EB_t^{2n} = (2n-1)!! t^n\) where \((2n-1)!! := (2n-1)(2n-3) \cdots 3 \cdot 1\) Hint: Use integration by parts as well as induction. (2) \(EB_t^{2n-1} = 0\) Hint: Use symmetry of normal distribution.

Step 1

Step 1: We need to prove that for Brownian Motion, we have: EBt2n = (2n-1)!! tn, where (2n-1)!! := (2n-1)(2n-3)---3·1, for Vt, n≥1 integer. Show more…
