    Hmmm... you were the one who called a poor soul a retard earlier, no doubt with that attitude you'll be aiming for Cambridge or Oxford. Am I right?
    Did not call him a retard. I told him it could be factorised he disagreed. I showed him the answer he says it was wrong and expanded it wrong basically calling me an idiot and saying nice try so I then called him an idiot for not being able to expand two brackets correctly and claiming he was right.
    No I am not aiming for Cambridge or Oxford. Already got an offer just thought I could help people on here. Clearly some people don't like being told when they're wrong.

    like basically, you know how you apply for uni at the beginning of A2, so you get predicted grades based on your AS that go towards this
    so if you retake, what happens to that predicted grade, like do uni's know you're retaking or does a crap grade go forward until you get your retake grade back

    its okay, you dont have to explain
    im confusing myself tbh, lol
    You dont have to submit your predicted grades for A2, just have to submit what you got for AS,

    Q5
    and q7b If you can help me

    and q9.a
    5) find gradient of PQ, since its 90 degree angle, its perpendicular to QR.
    Equal that perp.gradient to PR and solve for A.
    b) find mindpoint of line, sub in those coordinates. Radius is distance from R or P to midpoint.

    7b) 360 - angle so 2pie - 2.2 then /2 it as triangles are equal.

    9) terms are a, ar and ar^2, I believe you have to find r.
    so, ar/r = ar^2/ar = k/(k+4)= (2k-15)/k and cross multiply.

    guys a little help here
    when you are working out the value of n for geometric series when do you use ar^n-1 and when do you use ar^n, because it will either say such and such in the n year is greater or less than a value find the value of n

    oh so if you screwed up AS your screwed for the course you want in uni

    When solving sinx=something within the range -360<x<360, after working out x by doing arcsin, I know to do180- and then 360+ from the cast diagram, but I'm really confused at to what calculation to do for the negative? Is it -180+answer?

    Thanks. I'm struggling to understand what you mean for q7b, maybe if you could say it in a simpler way
    ill try
    so a circle has 360 degrees so if you join all the angles around A it would = 360 degrees which 2pi in radians

    and you know that both halves are symmetrical cuz they go 4cm up and 6 cm radius each side

    this means if you do 2pi - 2.2 you would get the angle of BAD + DAC so because they're symmetrical you divide by 2 to get just the angle of DAC

    Sorry another question, do you have to write things like '360-a' or '180+a' to get m1 marks on trig questions?

    why is that in the ms

    why is it that when u inverse sin (-1/5) u can also do inverse sin (+1/5)?

    No, if your predicted grades are believable and the University can be convinced then they won't care. Trust me. I got ABCC last year, and got a reduced offer from a university offering AAB (It was AAA but they dropped it to AAB for some reason, then reduced it for me to ABB). It was to do Computer Science.

    I did get asked in an interview why Computer Science if I got a C in it, and I gave a stupid response (I was expecting they would ask that but never thought how to answer it lol) but I still got AAB from them.

    "lol I find it funny how no one has answered your question" because you could either do sin^-1(1/5) ans +180 and 360- ans or you could do sin^-1(-1/5) 180 -ans and ans
