maths 9709/32

[Saloon]

hey as anyone else written the maths p32 yet?
pls say how you thought it was
I thought it was quite challenging, there goes my A

thanks

 

[Saloon]

oh shoot i have to wait 24hrs :/.... how do i delete a thread?

 

[dawatashi99]

too much qns.. didnt even c the last one.. i didnt know there was a qn on vector.

 

[oohlala]

The Exam wasnt easy
there were a cpouple of challenging qns. :/

 

[Zaryab]

The grade threshold will be low in this paper. Hope for the best. Are we allowed to discuss the paper now ?

 

[MuammarW]

For me it went well wasnt that bad....now i just hope my answers are actually the right ones -_-

 

[imagine]

I must say... EXAM WAS REALLY x INFINITY TOUGH!!!

 

[sadabrahman]

IT WAS SERIOUSLY TOUGH

 

[Saloon]

lol thought i was the only one who thought it was quite difficult... now i have to kill the stats paper! and i'm carrying forward a freaking B for AS maths bleh! should have rewrote that too.
hope the dude that marks my paper is high so he gives me free marks

guys did u get that volume question i guess i got it wrong and i just wanted to make sure

 

[kemotraceur]

actually i know i got it wrong just wanted to check if it was only me who got it worng :S :S

 

[usernameistaken]

Fairly hard.I'm expecting 60-63.

guys did u get that volume question i guess i got it wrong and i just wanted to make sure

i remember that, the one with the rotation... you had to integrate pi y².
i don't remember the exact answer but i got pi, e³ and e²... i don't know if its wrong though, i think it is.

what was the answer for that trig equation with cosec sec and cot.... i got 90,180 and 270, think i got that wrong too

 

[JackTheRipper]

The one with the volume had integration by parts and the result was pi(e^2-1)/4. I'm sure it's right.
I was too retarded during the exam to solve the differential equation so I missed 6 marks but I think it's just that.

Anyone got the final vectors answer lambda = 3 ? I know there are two possible points but I couldn't get the second one (the equation was linear). Perhaps -3 ?

haha, i guess u got the same answer as mine, which is wrong
there is no e³, the answer is gonna be pi/4(e²-1)
as for the trig question, i cant really remember the final answer, but i can tell that u had to solve it as quadratic equation in sin

yes u got that volume answer right,
as for the vectors, i solved it in a completely different way, i didnt include any lambda in my way, but i got the final answer right which was 6 i guess

 

[Zaryab]

I got the final answer in vectors which was 12. It is the distance between two points.

I got the final answer in vectors which was 12. It is the distance between two points.

It was supposed to b in the form I j and k! Or was it?

 

[JackTheRipper]

Didn't they provide a huge ass equation in the vectors question ? I substituted the general point P (with lambda) along with the plane substitutions, equated both sides and got it 3.
I had no idea how to get the second point since it was only one lambda. I don't think I'll lose too much though.

Lamba was 2!
