Ibsurviving Posted May 15, 2014 Report Share Posted May 15, 2014 Found it pretty difficult. Especially the binomial expansion part. Reply Link to post Share on other sites More sharing options...

Abdelbari Posted May 15, 2014 Report Share Posted May 15, 2014 It was REALLY EASY!!! easier than that compared last year and the years before!!! I do agree, the questions regarding the binomial expansion, calculating the perimeter of sector and the last sub question of Q10 were a bit tricky... However, the questions that I LOVED the most were about bacteria and cars Reply Link to post Share on other sites More sharing options...
christie.shum Posted May 15, 2014 Report Share Posted May 15, 2014 I thought it was MUCH easier than the previous papers but the binomial expansion was really annoying... I tried to take the easy way out without expanding the whole thing but that completely failed and I had to expand everything in the end... *sigh* 1 Reply Link to post Share on other sites More sharing options...
thirdculturekid Posted May 15, 2014 Report Share Posted May 15, 2014 I was quite happy with how it went, actually. Thought it was much easier than paper 1, that's for sure! Reply Link to post Share on other sites More sharing options...
I3lackAngel Posted May 15, 2014 Report Share Posted May 15, 2014 The exam was quite okay, although I ran out of time and couldn't solve some quetions The binomial thing with the constant term was very tricky.. I kind of know how to find the constant term, but I did not know how to do it the other way around :/ I think preferred paper 1 though. Reply Link to post Share on other sites More sharing options...
Mavourneen Posted May 15, 2014 Report Share Posted May 15, 2014 I found it quite reasonable.The binomial expansion question took me ages to complete and all the shortcuts lead me to a wrong answer. I liked the probability question at the end Reply Link to post Share on other sites More sharing options...

malice Posted May 15, 2014 Report Share Posted May 15, 2014 Binomial expansion? I thought it was easy, but perhaps only because I did an almost identical exercise the night before. I also think I had too little time, so at the very end I had like 5 minutes for the probability question and I was writing like crazy - if I made some errors I hope I'll still get the points for method.

XXX Posted May 16, 2014 Author Report Share Posted May 16, 2014 Paper 1 was much better for me. I couldn't solve the binomial expansion question either so I said: "Oh I will come back to this." and only drew an extended version of Pascal's triangle like an idiot then I ran out of time of course. By the way, did the revolution question create a sphere or did I have to solve it with a formula? I assumed that it would create a sphere without looking at the integral formula in the formula booklet Reply Link to post Share on other sites More sharing options...

I found it to be such a relief... One question, for the bacteria question 8, when they said after how many nth hours is (A) greater than (B), did you write 5 hours, or 4.78 .... What I undertood is that they wanted full hour. Reply Link to post Share on other sites More sharing options...

For those of you who did get the binomial expansion problem, did you get K = 2? 1 Reply Link to post Share on other sites More sharing options...

Hey,, yes for the bacteria question I answered 5 hours as well as they wanted full hour (I got 4.something something, but as they want the pop. to exceed so yeah) For the binomial expansion, I got k= 2 Reply Link to post Share on other sites More sharing options...
JojoOfthemojo Posted May 17, 2014 Report Share Posted May 17, 2014 Much easier than paper 1 for me, mostly cuz I wasted too much time on paper 1 and neglected to study vectors properly. I dunno, everything in this paper was cake cept for the binom expansion question and prob distribution which I didn't study for. Reply Link to post Share on other sites More sharing options...
