kevinsheng Posted November 7, 2010 Report Share Posted November 7, 2010 How was it? I thought it was a lot harder than paper 1. Reply Link to post Share on other sites More sharing options...
Jennifer Posted November 8, 2010 Report Share Posted November 8, 2010 Really? I found Paper 2 a lot better than Paper 1, although to be fair I found Paper 1 horrible so I suppose it's not saying much. What didn't you like about it? Reply Link to post Share on other sites More sharing options...
famvu91 Posted November 8, 2010 Report Share Posted November 8, 2010 its not that bad, only the geometric question 7^n something was totally horrible Reply Link to post Share on other sites More sharing options...
genepeer Posted November 8, 2010 Report Share Posted November 8, 2010 I absolutely hated the last question with f(x)=(a+bex)/(aex+b), I stopped at part c... and the one in section A about finding the gradient m and point of intersection of curve and tangent. Those two make it harder than paper 1 for me but otherwise it was almost same difficulty. Reply Link to post Share on other sites More sharing options...
The 45 Posted November 9, 2010 Report Share Posted November 9, 2010 Yes Paper 2 was easier, except for that last question.Ahh, but i got really sick during it and had a migraine so did not finish. Reply Link to post Share on other sites More sharing options...
faith Posted November 9, 2010 Report Share Posted November 9, 2010 I agree with The 45. In general paper 2 was better than paper 1- I made a decent attempt at all the questions. Reply Link to post Share on other sites More sharing options...
quietpenguin6 Posted November 9, 2010 Report Share Posted November 9, 2010 Paper one was much much harder. The vectors Question in P2 was excellent - it was like they were throwing marks at you by guiding you through each step. That said, the tangent question with three variables (x,y,m) was a bit of a nightmare... Reply Link to post Share on other sites More sharing options...
rFumachi Posted November 4, 2011 Report Share Posted November 4, 2011 This paper was easy until section B, complex numbers and vectors were my downfall . And yes paper 2 was easier than paper 1, now I'm looking forward for paper 3. Reply Link to post Share on other sites More sharing options...
zx898 Posted November 4, 2011 Report Share Posted November 4, 2011 damn...I found paper 2 so much harder than paper 1... I could do almost all of the question in paper 1 and I know I've got most of them correct..but paper 2... I simply just blanked out on the stats and that modulus/argument question, wasted so much time on section A, didn't get time to consider much for section B, made a few weak attempts and I hate vectors now Where is calulus for paper 2?! > not enough calulus imo.

amy11 Posted November 4, 2011 Report Share Posted November 4, 2011 i thought paper 2 was much harder than paper 1. i couldnt do most of the section B questions, only got the vectors question. the sequences and series question and the last question was impossible Reply Link to post Share on other sites More sharing options...
saunders is god Posted November 4, 2011 Report Share Posted November 4, 2011 yeh not enough calculus in paper 2 and too much on sequences/series Reply Link to post Share on other sites More sharing options...
United4Life Posted November 4, 2011 Report Share Posted November 4, 2011 I definitely thought paper 2 was easier than paper 1, probably because there was virtually no calculus Screwed up the very last question as well as trying to solve u in the complex number in section A (I only got one solution LOL ) For the arctan question did you guys solve it using your calculator or by using compound angle formula?

amy11 Posted November 4, 2011 Report Share Posted November 4, 2011 For the arctan question I basically took tan of it then took the arctan again. Not sure if ur allowed to do that. Did anyone get the sequences question part b? I spent soo long trying to do it but failed. Reply Link to post Share on other sites More sharing options...

Did anyone get the sequences question part b? I spent soo long trying to do it but failed.Don't really understand you sorry about the arctan. YES! Only right at the end, didn't get it the first or the second time I looked at it but had an epiphany with 5 mins to go. Using u1=a^2(1-r)^2 and r=r^2 and substitution into the sum formula it re-arranged itself. Reply Link to post Share on other sites More sharing options...

Would u guys say that paper 1 and 2 was hard compared to other years. I wanna know if it'll be likely that they lower or raise grade boundaries. I really need a 7 for maths, it's a prerequisite for the unis I'm applying to Reply Link to post Share on other sites More sharing options...

Yeah but it was originally from a paper 1, so you had to use compound angle formula. To stick in paper 2 was odd because you could simply solve it on your calculator....

amy11 Posted November 4, 2011 Report Share Posted November 4, 2011 I'm applying for economics at cambridge and london school of economics and its "ideal" to have a 7 in HL maths, which basically means i need a 7. For arctan question, it was like solve arctan(1/2) + arctan (1/3). what i did was tan(arctan(1/2) + arctan (1/3))= (1/2 + 1/3)/ (1- 1/2 x 1/3)= 1 then i took tan(1)= pi/4. i didnt do the past paper which had that question on it, so i completely guessed it...

zx898 Posted November 5, 2011 Report Share Posted November 5, 2011 nah that's how u do it. U did it the right way! Congrats! Although I think u may have used the wrong formula? But good luck for your uni application I'm applying everywhere...Has to do my SAT right after the exam finishes... SAT's on 3rd December and my exam finishes on 11th Nov... Haven't done any practices...so...20 days to get above 1350/1600 for math+english in SAT It will be fun... I want to go to Wharton college for finance or stanford for fiance or university likewise..So...pretty ambtious of me Reply Link to post Share on other sites More sharing options...

Cool thats what I did except I thought the question was arctan(1/2)-arctan(1/3)= arctan(a)? so I ended up with tan(1/7)= a.... Hope I got method marks.....
