Hello it’s me again.
Something landed on my lap this afternoon, followed by what I could almost hear was a thousand screams of anguish coming at the end of today’s H2 Maths Paper 1.
To find out what happened, I’ve worked out my own suggested answers which you may access here by clicking the 
button (if you haven’t yet done so).
Latest version:
- 1.1: Added the constant of integration (+c) to the answer for Q8(i) -thanks clarionx!
As usual, please leave a comment should you spot any mistake in this set of suggested solutions, which was produced under the peering eyes of some students from today’s class *sweats*
Oh by the way, do say hi to me when you drop by in Facebook 😉
Now go revise your
- Functions (composite & inverse)
- Transformation / Hyperbolas / Curve sketching (oblique asymptotes) (remember to use Radian mode should you be called to sketch a trigo graph!)
- Integration by parts/substitution/ Volume of revolutions
- Recurrence / Sequences (Tn = Sn − Sn−1)
- Complex Numbers (Rationalization & Simultaneous Equations)
All the best for your Paper 2 on a very auspicious (I hope) 11-11-11!

@clarionx: Thanks for pointing this out - uploaded v1.1.
BTW clarionx, my sister says "Long time no see!" 😉

hi,
for q2ii) for f(x) to be an increasing function, why is f'(x)>0 and not f'(x)>=0?
Isn't f'(x)>=0 was for strictly increasing functions?
Hope you can help! I'm confused ><

@cyx: sorry, i meant:
"isn't f'(x)>0 for strictly increasing functions?"

@cyx: Strictly speaking, f'(x) ≥ 0 should be used since Q2ii only mentioned "increasing function" (without the "strictly").
But then again, since most TYS solutions (including one exam report below) used f'(x) > 0 in the answer, coupled with the fact that AMaths students are brought up with the knowledge of increasing function ⇒ f'(x) > 0, we suppose that either way should be accepted at A Level.
Good luck to you for your paper tomorrow!
