(1/144)e^2 anybody?


I believe that's the accepted answer. I must have made an arithmetic error somewhere... So stupid.
70 in C3 and 64 in C4 should get me an A* right? Annoyed that I made some silly errors today....
What exactly was question 2 and 3 anyone? Like the actual question.
anyone remember the implicit differentiation q?

would you get full marks for not multiplying by x^2 or -1 mark?


I Think -1

I Think -1


Why would it lose marks? The answer's still correct just in an alternative form, right?

I'd be surprised if you dropped a mark, it's still correct

Overall was quite a difficult paper, but I found what really made it worse was the time management, especially for question 9
on the markscheme, the integration by substitution q is only worth 6 marks, not 7.

Very likely.

These grade boundaries will be my only shot at uni
A* 5/72
A 1/72
B -3/72

i really dont recognise that implicit differentiation answer...
Neither do I, if anyone knows question 2 and 3 please post it.

I think there will be a simply mark
When drawing the graph on question 9 did we need to include the entire graph or the graph between limits of t?

Can anyone remember how to get the Cartesian equation in question 9?
I got 2x^3 - 6x^2 + 5x but i don't think its right


thats what i got, and values of minimum points were consistent between the two forms
