    question 2 needs sorting and for vectors I swear it was E(11,0,0) and E(23,4,-8)
    I got roughly the same.Can't be an other 0 as y value in the one with 23 as x value

    7a) i got k=1/4+ln(2)
    Was definitely - ln2 .

    65 for an A*
    respectfully disagree because it hasn't been that high in few years and this paper wasn't easy enough to warrant a 6 mark increase for the A* boundary. 66 probably the 100ums cap

    My predictions:
    60 A*
    55 A
    50 B
    etc etc
    because it wasn't SOLID like we expected, but it was challenging and maybe a bit more difficult than last years but were supposedly getting 'smarter' so I think an increase of 1 isn't too unfair
    I thought it was easier than last year. If you look through last year's thread it seemed like an absolute nightmare at the time when most people here seem to think this was alright, I hope I'm wrong but I think 2 higher than last year's, maybe 3 if I'm being pessimistic but probably not.

    Nah it's a little too low, not being biased i kinda thought i should have done better but i would say 57 for an A 64-65 ish for an A*

    I have a question

    for question 2 b

    would there be 4 values for the degrees?

    because it's sqrt, hence +- ?

    I doubt you'd lose any marks for it, the mark scheme would likely say "or/condone [insert the angle in radiains]".
    Thanks ;D

    Was C (15, 6, 2) or (15, 6, -2)?

    Potentially, did anybody else show x tending to infinity = 2x-3 tending to infinity = 1/(2x-3) tends to 0? Therefore is decreasing. (Idk if it was 2x-3 but was something like that)
    I did this too with limits, and then I drew a quick sketch of the graph and pointed out that after x=2 the curve was tending to y=0, so decreasing.

    how because the equation is y^3 + 2e^(-3x)y + x = k so you'll end up with
    (1/2)^3+2e^-3ln(2) * 1/2 + ln2=k

    yeah fair comments, but there were some tricky questions and obviously vectors is a whole different matter. I don't think 65 will be an A* as like I said a 6 mark increase suggests the paper wasn't challenging to most people. whereas general consensus is the exam is tough but fair, so yeah maybe 61/62 A* highest
