Additional Math Paper 1, how was it?!

[Rashmit]

Mine wasnt how i expected it to be.. the paper was crazy difficult compared to the 2009 p1 and even the 2010 p1! :|

 

[yannickhow]

Mine was fine, it was a bit "easier" than i thought . hope that tomorrow will be okay also

 

[usama1993]

Mine went very well !!!!!! :mrgreen: :mrgreen: :mrgreen: :mrgreen: :mrgreen: :mrgreen: :mrgreen: :mrgreen: :mrgreen:

Except for the question number 11 lsat part

 

[yudish9]

fair paper ....the remianing chapters will come tomorrow!!!

 

[carolinetcw]

can anyone please help me. i can't get the answer right. this is on vector..

THE POINTS P , Q AND R ARE SUCH THAT QR=4PQ , GIVEN THAT THE POSITION VECTORS OF P AND Q RELATIVE TO AN ORIGIN ARE 6i+7j AND 9i+20j respectively, find the unit vector parallel to OR.

URGENTLY AND THANK YOU!!!

IT WAS SOOOOOOOOOOOOOO EASY. seriously i dont knw why people found Q 11 difficult. My czin was appearing and he couldnt do it but it was quite easy, all parts. i did a careless mistake in Q10 but apart from that, to the best of my knowledge there were no other mistakes. aiming for a 78/80

 

[HarisShahzad]

QR=4PQ
OR - OQ = 4(0Q - OP)
OR = 4(OQ-OP) + OQ

Solve and find OR

find magnitude of OR and then divide OR by its magnitude

Mine was also gr8 but only question 11 last part wasnt good because of shortage of tym...
I was very much relaxed when i realised taht i am short of time

 

[HarisShahzad]

great...i didnt run out of time just made a silly mistake----i knew how to solve the paper yet i made a silly mistake

 

[Smart-Guy]

the paper was outstanding, fantastic, fabulous.....
I think i just lost 4 marks only
but..... still some silly mistakes

Haris Shahzad....r u talking abt the same paper (IGCSE paper 1 variant 2)i gave?

Lets see...whatdhja get 4 Q 11....which ur cuzin dint do( integration)

 

[HarisShahzad]

part two, the one that said differentiate in form A/[sqrt (1+x)] + Bx/[sqrt (1+x)]^3. A was 2 and B was -1. third part was integral of x/[sqrt (1+x)]^3 with limits of 0 and 3, the answer was 1

 

[Dracula95]

right!

 

[HarisShahzad]

really

 

[Dracula95]

yeah...the circular measure was 47.7 and 30.7....i got a silly mistake in th perimeter part
and what else?

 

[HarisShahzad]

correct . I chose twelve Either. didnt even look at or. EITHER was highly easy. there was also finding the rate of increase of volume. we had to find that by dV/dt=dV/dx * dx/dt. to find dV/dx we had to find volumes formula. IT was 4x^3 but i accidently wrote x^3. ill get marks for the method but still im dissapointed

 

[Dracula95]

yeah i got 0.09 for that....either was easy i got y=Mx-8 i dun remember what m was

 

[HarisShahzad]

m was smthin like 1/6 or -1/6

 

[Heshna]

for p1...the question on rate of change... the answer was 3x10^-4 and 0.09???
