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??

Please tell me I'm not the only one who found that an absolute nightmare.

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?

that was rough. Couldn't do any of 9 and parts of 6- does anyone know if a mark scheme is coming up soon?

I got 17m too for x

I also got 17

Such a sick paper

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

i found the paper pretty good. I would say it's far more challenging than the past papers, but I found this pretty chill

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?
