116π/3ln3 for last question?
YES!!!
2. What was the last question on the paper, I'm worried I've missed one
3. (Original post by Tazmain)
Waiting for the hitler video,

Even though it wasn't that hard.
Bar last part of question 8 and actually reading the question for the last part of question 7 (which I didn't do )

Lol same just glad I wasn't the only one.
I eventually concluded that there was a mistake in the paper and moved on, it's not exactly unheard of haha. Only a 3-marker though
4. Yeah I got k=4 as well. I remember in the next question it become 2 after we got given something (I know vague). Will see I guess with Arsey.

Also, for grade boundaries I think at most it will raise by is 1 imo. Perhaps 67 for a*, I don't think it will be any higher.

Rings a bell! for the volume of revolution I got 13pi / ln3, any confirmation?
i got 2 - 1/ln3 and 13pi/ln3 for question 8

i even didn't have time to read the question.. the one of finiding t ...i didn't even knw the population was in 1000
gosh this paper!

5/2 x t^-1 differentiate to -1x5/2 x t^-2
You did the intergal of 5/2t to 5/2 lnt
Thats my A* ****ed hopefully get the one method mark for doing the dividing correctly.
Can you remember what the second part of the question was?
8. (Original post by DomRauba)
Guys, what was the x coordinate , i got 2- 1/ln3
That is correct.

Volume was 13pi / ln3
9. guys was the years did u youse degrees or radians?
10. has arsey done a mark scheme yet?
11. well i got rekt by that exam
12. Ok let's try to put a previsional MS before Arsey
1.3sqrt(2)/2 ; 181/128
2.
3.
4.
5.
6.
7.
8.13pi/ln3

Anyone remembered the question?
13. K= 4 ??? 2 in the square root of 4 and 2 in the 2cos theta???
14. What did people get for coordinates of stationary points?

Am I the only one who struggled A LOT?
There's at least two of us mate

i got 2 - 1/ln3 and 13pi/ln3 for question 8
Spot on
17. What were the answers to vector question?
18. (Original post by Tina.Shaban)
Would the answer for years be in radians or degrees? Wouldn't it depend on the species of animal and how fast they reproduced
HEYYY GURLFRIENDDDD

It's shams lmao
