AQA A level Maths Paper 2 Unofficial Marks Scheme 12th Jun

How did everyone find paper 3

How did everyone find paper 3

you know the question with the teachers who were categorised due to their exercise and the question said there was 120 teachers but if you added up all the elements within the table you got 114 teachers ?!? what’s up with that

Did anyone get the area of the segment as 16.9? And for the integration I can’t remember the number but it was ln81/16 or something right?

Was this the Maths 2019 Paper or Further maths 2019 paper?

Q1: D (graph with maxima in top left quadrant)
Q2: $a^{\frac{8}{15}}$
Q3: $x^2$
Q4: Show that. Factor theorem on both, set equal to each other, rearrange
Q5: $t^2 = \frac{-2}{x}(\ln{x} + 1) + 6$
Q6: a=2, b= 2root3
Q7a: show that, differentiate, stick in 0, differentiate again to prove not point of inflection
Q7b: $-4p^3<q<0$ (turning points must be one above and one below x axis. Minimum when is x = 0, maximum when x=-2p)
Q8b: p=7940, q=1.08
Q8c: 2021/2022/2023. It depends on whether you use rounded or exact values from part b. It didnt specify which to use- so like physics, these will all probably be accepted
Q9b: between plus/minus root2
Q9c: 0.39467
Q9d: invalid as the value is outside the range of a small angle approximation (as derived from maclaurin series)
Q10: B (deceleration)
Q11: 1000N
Q12: - 400
Q13b: teacher is correct- resistive force should make it lower than expected; it's actually greater so machine must be faulty
Q14b: Moments, n=3
Q15a: show trapezium- show that two sides are parallel, the other 2 are not (eg show multiple, use dot product methods etc)
Q15b: 17m/s
Q16a: 11.5
Q16b: $s=11.71t + \frac{584}{45} e^{-0.9t} - 0.1e^{0.3t} - \frac{1159}{90}$
Q16c: the model is good, as if you sub in earlier values, you get very close to 100
Q17a: show that. N2L and resolving
Q17b: parts a and b rely on the limiting case of friction as nonzero velocity- as Lizzy and her sledge are not moving in the new case, friction is likely to be less than μR

what year is this paper.. 2019?
