1. how did we find it all?

like the differentiation question?
2. What did everyone get when substituting their x value into the 2nd differential to show it was a minimum point? (very last question part e)

I got a really small decimal??
3. couldn't do Q6 or 9 so i have lost like 20 marks anyone else the same?

wat?

it wasn't small decimal....

x was 17m to the nearest meter what did you get?
5. Please tell me I'm not the only one who found that an absolute nightmare.
6. For the question that said i cant use any graphical or numerixal method to solve, i used identities to find a form where i could factorise it. I did so and then found theta with the 180-theta +360n method. Will i get marks?
7. that was rough. Couldn't do any of 9 and parts of 6- does anyone know if a mark scheme is coming up soon?
8. I got 17m too for x
9. I also got 17
10. Such a sick paper
11. Guys it asked for P not x, so 17 is wrong because you had to substitute in x=16.633 and then you get 120 to the nearest metre

Question asking for P as nearest cm so I think you need to sub the x value as 16.63...into original equation to find out P (I got 120) to nearest metre

You had to put X back into the P equation and THEN substitute it into the 2nd differential
14. When does BTEC maths start?
15. i found the paper pretty good. I would say it's far more challenging than the past papers, but I found this pretty chill
16. it was absolutely nightmare
17. Did you guys get for the log question 0.47 or something? And for area of S where integrate with limits to get the area, one limit was 0 and I go 3 as the other limit, what did you guys get?

S = 24.3

it was 0 to 9
20. hated it
