    in the c4 book, pg78 8c.
    the question is a bit weird.

    its not asking for the angle between oa and ob like it usually does.
    its asking for ab and oa.
    how do u do that?

    using the scalar product formula, i used ab =a and oa = b.
    but i still dont get the rite answer?:confused:
