    Cos nobody in their right mind would do that, especially one:

    1. Studying maths at A2- Obviously a bright pupil
    2. Discussing the exam- If you just started then you obviously don't care about the exam, so why are you talking about it?

    In August you'll be back on saying "oh my god I revised for 1 day and got an A, woo"

    Yeah, okay, fair point, obviously i've gone over everything after lessons, if you count that as revision, and I haven't been able to have a proper good revision maths day RECENTLY because my week's been jam packed with exams.

    So maybe you shouldn't just jump to conclusions every time you see something which can be misintrepretated. Because obviously if I am discussing the exam, which means i care, would mean i've put slightly more time in.

    And no, i'm not going to get an A in this exam.

    So you have revised So you were lying, and why can't you get an A in the exam? I don't wanna take up any more of your time, good luck with the exam and wish you all the best

    they usually give you two line equations in form r=a+tb and r=a+sb where a isn't normally the same.
    anyway.
    say:
    a+tb=a+sb for (i,j,k) values and then solve one( eg:i) to make t=x+5s say, then put it into the j equation. you can find one of the letters from that. Then go back to your equation you worked out t=x+5s to find t.
    put your s and t into equation k.
    If htey intersect, they will be equal. If not, they skew.

    Hope that made some sense..
    Okay think I get it..... So work out s and t and put back into vector equations.... And the vectors should equal ?

    you have two vectors, equate them together to get 3 simultaneous equations. Use two of the simultaneous equations to find s and t (oe) and verify it using the third equation

    Yes. Just make sure you use all 3 equations once.

    Don't have the question at hand but do this
    E.g. (1,1,1) and (2,3,4)
    Just add each one and divide by two
    (1.5,2,2.5) is midpoint

    You may well have made a mistake.. when I did that question it was easy with very easy simplification.

    oh i misread your post.

    factorise the (4-u^2)... its the difference of 2 squares.
