    Hi guys quick question please help.

    In the jan 2012 paper we are told to find the coordinates of D where the rectangle is ABCD and looks like this D------------C
    ! !
    ! !
    A------------B

    I understand the rest of the solution to the question but the mark scheme says (vector) OD = OA + BC
    Can someone please explain this to me I don't understand how this is the vector expression for OD.

    Thanks

    hoping for long binomial question and long implicit diff question. Maybe reversing the Rcos(x+a) to trick some people and some c3 stuff

    It's not a trick but they could write excess asinx + bcosy in Rcos(x-a) so ppl get the tan the wrong way round
