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 :angry:)



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 :smile:
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.

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!

Rings a bell! for the volume of revolution I got 13pi / ln3, any confirmation? :smile:


i got 2 - 1/ln3 and 13pi/ln3 for question 8

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 :frown: hopefully get the one method mark for doing the dividing correctly.
Can you remember what the second part of the question was?

Guys, what was the x coordinate , i got 2- 1/ln3


That is correct.

Volume was 13pi / ln3

guys was the years did u youse degrees or radians?
has arsey done a mark scheme yet?
well i got rekt by that exam
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?
(edited 8 years ago)
K= 4 ??? 2 in the square root of 4 and 2 in the 2cos theta???
What did people get for coordinates of stationary points?

There's at least two of us mate

Spot on
What were the answers to vector question?
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

YES!!!


God. There is hope yet if so.

Barely had enough time to do Q9, I nearly missed it!


That joke is as funny as it is original..
Did anyone get 27/32 for the gradient with parametric?
For the question where you had to find the years if the population is 4000. What if you left your answer as degrees? So 27 years or something like that...?
