    Hi, I've attached 2 questions in one file. Thanks.

    Question 1 hints:
    Hint 1: you have a process Y and a function, the first instinct should be to try Ito.
    Hint 2: what would the SDE of a martingale look like? Look at attached lecture note.

    Question 2 hint:
    Hint: use the integral version of Ito's formula.
