MATHS PAPER 32

[ima_shah2002]

HEY GUYS
had my maths paper today, paper 32 ,it was okay...had some doubts in da 7th vector question , can someone please help me!!!! .... is neone else done...

 

[soumayya]

i've done it too...overall the paper was fyn..i fink we can't discuss the paper until 24 hrs are over...so...later...

 

[zizu]

naa....it was not sooooo easy...many students failed to do the vector question!!

 

[alevel pedit]

the paper was very easy .. i hope the threshold mite go up .. the vector question was very easy !! .. if you post the question i will solve it for you..

 

[MAVtKnmJ]

Only after a few hours you can discuss this paper.

 

[Shafaque]

Maths paper was comparatively easy than wat came in May/June 10
However made some blunders
I dont think that threshold will go up then..65 for an A

What did u get 4 the equation of plane...?

 

[ima_shah2002]

hey the vector equation , part b was find position vector and c was to find plane perpendicular to plane OAB which has line l , for second i got my answers in some fractions like 10/3 , 5/3 or somethin for last i got something 2x + something + something = -14. nething similar guys

 

[zizu]

i got it equal to zero me!!

 

[soumayya]

i got d equal to 26 in equation of plane...

 

[loly23]

i got it equal to zero like u zizu!!
the co-ordinates of p were strage fractions???

 

[soumayya]

how cme it's 0..? did the plane pass through the origin..?

 

[loly23]

its normal yes!
i verified my answer by replacing the eqn of line AB in it and i worked,so i guess it's right

 

[Shafaque]

My co-ordinates of P were not coming in fraction :? :?

 

[johnybravo]

i got the d = 0 in the vector third part...
and the second part was out of my knowlege.. P remained unsolved
does anyone have his answers to compare!.. i wanna compare mine...

thXx guys..

 

[Cyan]

you've got it right.. It's 26

 

[Afghan]

ya even i got the equation of plane as d=0, but my friend got it 14. The second last question, i got the coordinates for the minimum in e form, i guess it was like e^-1/3 and suming. Overall it went great, but missed that expansion part, the cot graph thingee, and couldnt show that angle was pi/6 in the argand diagram question.
So its like i completely lost 12-15 marks!! i may get around 55+-5. so hard chances for a B i wud say.
Anyways, better forget about it and focus the coming stats paper...damn does it suck!!

 

[zizu]

cyan...i'll try to rework the question and see!!!i bet its not 26!!!!
anyways what did you get for value of x when t=10 in the differential question????

 

[soumayya]

i got the d = 0 in the vector third part...
and the second part was out of my knowlege.. P remained unsolved
does anyone have his answers to compare!.. i wanna compare mine...

thXx guys..

u can post ur answers hre...haven't got my paper yet...

 

[Depletion]

soumaya:yessss....26 is the correct answer...=)
the paper was soooo easy...the differential was like WOW..!!
