    Ok I've attached my working because im still stuck on getting the final answer

    You're almost there. (R-A)xB=0 is the equation of a line, right? The question is asking to bring it in the form of RxB=AxB (where B is the a in the question and AxB is the b in the question)

    You know the B, which is your a (-2i+5j+13k). And the A would be a point on the line, which is the point of intersection you worked out (15/13i -5/13j) If you cross product these two you will get your b.

    I'm sorry but I don't understand what you mean when you say cross product and was wondering if you would mind showing your working on a piece of paper?

    Hope this helps. I'm assuming the working you've posted earlier is correct, which I'm sure it is. Hope it makes sense

    hey guys, what proofs are we supposed to know for this exam? like i think we need to know (AB)-1 = B-1A-1 but any others?

    Thanks that helps a lot! I was being silly in my calculations and accidentally used 15/13i and 15/13j instead of 5/13j which I had written down but some how put into the calculator incorrectly!

    According to Edexcel, this is what I need for my FM A level.
    GCE A Level Further Mathematics:
    • AS - Further Pure Mathematics 1, Application or FPunit, Application unit
    • A2 - Further Pure Mathematics 2 or 3, Application unit, Application unit
    And to get an A* I need 480 overall, with 270 in 3 A2 units.
    Based on this info, does it mean that if I put FP1 (93 UMS), FP2 (maybe 82 UMS), D1 (95 UMS) as my AS units, and M1 (maybe 92 UMS), M2 (maybe 95 UMS) and FP3 as my A2 units, that I need 83 UMS in FP3 to get an A*? Or am I understanding it wrong??

    FP2 can be counted for A*

    I'm a bit confused on june 2009 3b, it's quite straightforward but I think I'm messing up somewhere I got to the stage of where the markscheme says y=4z but then I am not able to translate that to the final stage and be able to come up with the eigenvector

    So if I've done slightly better than I think in either FP2, M1 or M2, then I can get an A* and don't have to worry as much about FP3?

    any unit which finishes in 1 DOES NOT count for A*
    (M1 cannot be counted)

    Yeah I've focused on my other exams, and haven't studied for FP3 or S2 in ages. This is the issue with exams at the end of exam season.

    It's especially annoying when you know you might as well have not bothered. I would say that S2 doesn't require too much study but the Jan 2015 paper was horrible and Edexcel seem to love their hard statistics in general this year...hopefully the trend of standard FPs will continue.

    Nope. Would love to be considering I may have missed my STEP grade.
