    Hi

    I'm doing the C3 and C4 exams this year for OCR.

    I wanted to know if it matters what format the vectors are in?

    E.G. If the mark scheme says (9i+3j-2k), and I wrote (9,3,-2), would I lose mark/s?

    If you meant (9, 3, -2) as column vector which you typed horizontally on TSR for convenience, that's fine - if you literally wrote it as (9, 3, -2) on paper (i.e: horizontally), then no - that's not a vector and isn't fine. Column (i.e: vertical) vectors are fine instead of i, j, k. (unless the questions specifically asks you for that format, of course).

    Thank you very much! I did try to put it as a vertical vector, but it just looked stupid.

    No problem, sometimes I give my vectors as (x, y, z)^T for the bantz. :lol:
