I used the double angle for sin and cos and used tan2x as a fraction of that and simplified. It seemed to work.
7. For the question with the simplifying fractions (I think it was 8), does this method work?

(x^4 + x^3 - 3x^2 + 7x - 6)/(x^2 + x - 6) = x^2 + A + B/(x-2)

If x = 0,

-6/-6 = A - B/2

If x = 1

0 = 1+A- B
B = A+1

1 = A + (A+1)/(-2)
-2 = -2A + A + 1
-3 = -A
A = 3
So B = 3+1 = 4

Not really there were 2 ways you could have done it you melt, was referring to how we got exact answers earlier on in the thread as we discussed them.

I'm not trying to be annoying, but people would just be guessing.

Maybe, maybe not.

5 ii was 2cosec4y I think
Could you remind mhat question 5i was asking?
20. What did people get for 6a? I got A=3 but my remainder was coming out at 4x+13... I was putting -6+18 inmy calculator, repeatedly but kept coming out as 13 (wtf) ( I should have obvs done this in my head but I was trying to save time and didn't see the blatant mistake of not doing -6+18 in my head-.-) So I just left the rest of Q6 and dropped all those marks -.- becuase of my calculator.
My calculator also kept giving the wrong answer sin(-pi/3) (and yes I was in rad) for one of the questions - thankfully I went back and then it decided to give my the right answer

Destroyed my calculator. Now I need a new one for c4
