    Question 2

    I did part (a) (i) and got 4/3
    (ii) and got -root3/3

    For part (b) I did the expansion and subbed in the values, but I can't get it into the form required.

    Do you want to show your working it is very straightforward

    Note : I used -1/rt3

    I think that makes it much easier

    As I say easier if you leave it as -1/rt3

    But same principle

    Multiply by 3rt3
