    Q1(a) - 1/3N ???? Shouldn't it be 1/6N?

    nopev = 12/(x+3)m
    = 0.5work out F at x
    = 3F = ma = mv(dv/dx)v
    = 12(x+3)^-1dv/dx = -12(x+3)^-2
    so at x = 3, dx/dx = -12(6)^-2 = 1/3v
    = 12(3+3) = 2m = 1/2mvdv/dx
    = 2 * 1/2 * 1/3 = 1/3N

    Well, I got a 100 ums in C1 but I don't brag about it. Special people like us don't need to show the world our mad arithmetic skills nor our dope series summing techniques.

    At the end I really don't think the marks matter anymore. I finished my maths A-level in end of year 9 and got 100,100 and 98 for C3, C4 and M2

    And I think I was amazing in maths then I entered the FMSP competition without any practice

    And other student beat me like a baby

    It is very good for you to achieve such a high grade in C1, what I am trying to say is... nothing is based on talent without practice. It is just like me practice alot for math and i got good grades. I didnt prepare anything and got shreked in competitions

    By the way I'm not familiar with some words... what does surd mean in here? irrational root of interger?

    Omg :O !!! How can I make that error?! 😩😩

    I just differentiated v with respect to x, like a muppet. Multiplied by 0.5 and subbed in x = 3. How many marks out of 4 will I get for that?

    Apart from that question, I got the same as everything else on that answer list.

    I was joking lol. I think C1 100 is worthless tbh.
    Real maths is Step/olympiads.

    yea i have. just dont feel the need to boast about it like u guys do lol
    If you really beyond us you dont even think that we are boast about the grades, this is just a fact of evidence about the effort we've put in.

    What you are doing now is just like a prejudice against the good student lol

    Yeah it's perfectly fine to use the first part to answer the second part
    Okay this just gave me more confidence, hopefully this means I lose 1 mark for radius (B1 mark) and I lose A1 for horizontal equation and A1 for final answer and hopefully I get all method marks because my method was all correct (praying for nice examiner and generous mark scheme)

    I was being serious, I wasn't referring to myself. Enrico Fermi, for example, proved some equation about sound using second order differential equations when he was only 15
