My heart skipped a beat, thank you. I think I got 80-90 raw (hard to say without knowing how many marks they take off)

that being said, I completely guessed 40/3. This is why you should always put down whatever kids!

(ps. what would a raw 85 scale up to?)

This paper might be hard to predict a cutoff but should be around there... ~85 is my guess however seeing how most ppl got screwed over by a few of those questions then yeah

Sorry, that was a typo. Its actually B (2 solutions).

 

[Nukeboy]

For 15 c ii, did they want the co ordinaries of P in terms of m? I just put (.5,e)
And yeah, shouldn't 7 be C?
Sinx=1 has one solution between 0 to 2pi and tanx =-2 has two solutions between 0 and 2pi.

 

[Nukeboy]

Sorry, that was a typo. Its actually B (2 solutions).

Wait, how?

 

[Nukeboy]

Wait, how?

Ohh, is it because tanx=/=pi/2

 

[enigma_1]

It's 3 solutions for the MC question :/
Inversetan(-2) has two in the domain and sinx had one
