The day began with an innocent attempt at a prophetic tweet.

Only for it to be shot down soon after.

And so in a bright sunny binary day of 1/11/11, Captain Loi and her crew of sexy air stewardesses took off from The Temple to fly Jφss Sticks Airways Flight JS296 among the clouds once more – looking down at a million faces that seemed to bask in the (resigned) relief of the afternoon sun …

… following which the latch was pulled and the package released …

Latest version:

1.1: Changed all the “Factor Theorem” to “Factor Formula” in Q10 which Miss Loi had written mistakenly in her haste 😛

As usual, please leave a comment should you spot any mistake in the solution.

For those who might be feeling a bit down after this year’s “more-challenging-than-usual” A-Maths papers, be comforted to know that the evil bell curve should be working in your favour (instead of against you) this time.

Hope you can take heart from the following Singlish-ridden quote which Miss Loi has always said to downcast students in times of need (while patting their backs simultaneously) …

If everyone says difficult and you say die then it’s ok. But if everyone says easy and you say die then you REALLY DIEEEEEE!

Let the burning of Math books begin! But please don’t accidentally burn your books from other subjects 😛

Good Luck for the Rest of Your Papers!!!

Meanwhile last-minute air-drops cum tips for other O Level subjects are still continuing on the Jφss Sticks Facebook wall!

Yes that tangent graph's been waaaaaay overdue - every year Miss Loi was thinking "This must be the Year of the Tangent!" only to be pang seh-ed by it again and again 😛

Hi i would like to ask about the solution to 11 part 3 if it is possible to show that the line is a tangent to the circle by equating equations of both and obtaining a quadratic equation and hence prove that D = 0 ?

@NeedHelp: Here's Miss Loi's reply to a similar question asked on the Facebook wall:

Umm ... for a proving question like this, you're supposed to prove directly, instead of using the final 'proof' as part of your workings to attain your proof (this is beginning to sound zen-like ...) as you've done.

Would it be safe for me to assume that they will minus at most 3 marks for the differentiation Qn for the one with the lawn, if the value of r happen to be wrong? Because my dP/dr is correct and my d^{2}P/dr^{2} is also correct.... >< should have at least one mark each right?

@Lala: For Q6(iii), assuming that your mistake is only limited obtaining and substituting the wrong value for r, you should get be able to get at least 2 marks since the bulk of the 5 marks should go toward the derivation of dP/dr (and acknowledging P has a stationary value when dP/dr =0) plus your second derivative test - which your workings have to reflect clearly.

Hey Ms Loi, i know its virtually impossible to predict the moderation of O level papers. But i hope u can use ur awesome prediction skills and past experience to help me in something. Do u think that the A1 for this Amath paper (paper 1 + paper 2 combined) this year would be around at most 70% judging by the difficulty?? Please reply. I need some closure over this matter 🙁

@BOB: While as you rightly pointed out that it's virtually impossible to predict, Miss Loi can say with a certain amount of certainty that any moderation being done would almost always be pulling the base A1 mark of 75 upwards (towards 80) instead of downwards (towards 70).

Hopefully this will bring some form of closure to you *gives a squeezy hug*

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

The a maths paper 2 is ok... can get full mark if i am not wrong, seeing that there is only a tangent graph, which kill a lot
