how to show if $m(t) is a martingale in math where is m(t) what is the name of the formula for ito's t formula what is $m(t) what is $m+t formula what is b(t$ how to use m(t) formula how do i figure out that $M(t)=e*fract2sin(b(t)$ is a martingale what formula should be used to demonstrate that the price of the martingale is brownian how to show how $m(t)=efract2sin(b(t))$ is a martingale what is $m(t)= what the e formula for martingale if $m(t)=efract2sin(b(t)$ is a martingale ito's formula what is m(t)=e'fract2'sin(b(t)$ what's m(t)? what is the ito formula? what is the symphony between $b(t)$ and $m(t) if ito's formula is used in ito formula, what do i get what is ito formula how to show what is b(t)$ in ito formula
