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

hi, wat do u think will be the cut-off marks for A for this yr's paper? personally i feel this yr's Paper 1 is tougher than previous few yrs 🙁 Hopefully, there will be a decrease 🙂

@tkdka: i heard it's around 75-80 range, and im at the lower end of 70s, abit worrying :< but can't do anything abt it as well, since it's over. Just hope to know where i stand right nw 🙁

@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.

* Please refer to the relevant Ten-Year Series for the questions of these suggested solutions.

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?"
