No discussion allowed within 24 hours!
Thank you!
Come tomorrow and have fun discussing it

 

[msk]

Ok its not tommorow now
Yeah paper was a lil difficult...the ap/gp question was a lil tricky! i guess the most difficult paper in history becasue p1 is mostly strait forward!

 

[diwash]

Ok its tomorrow now and can we discuss?
I found the paper Pretty easy ....the only Q i am dought ful is the question askig to find the position vector of D i a parallelogram ABCD....
I did with the vector AB and DC are equal .
.so OB-OA= OC-OD..and thus found OD....is this a valid mathod...?

 

[mrpaudel]

diwash...yeah...its the same way..u got it correct....thats the way to solve that one...i was unable to do the sector question...n i m regretin now..!! I find paper little tough compared to papers of other years...though will get an A for sure..no worries..!!

 

[diwash]

Thanks dude....ya the sector Q was little bit tricky...but i was able to solve it..to get the answer 12.1 cm...it seems i have done all the Q Correctly..lets see hope to get 70+
and what about the graph part i have done it on the answer sheet itself...will that be regarded correct? As from earlier marking scheme and examiner reports..i have learned that it only the Sape of the graph and the range of the graph is taken into consideration and it does not matter where u draw....

 

[Ashmita]

yep it was tough bcoz of which i could not complete whole paper on time may b ill score around 50-60

 

[Nibz]

Tomorrow as in.. 24 hours after the paper!

 

[cescfabregas]

The most difficult paper the history has ever seen.
Let's see what happens.

I FOUND IT BY THE MIDPOINT METHOD...IT WAS EASY.
PAPER WAS VERY TIME CONSUMING I MUST SAY.....WHAT WAS BINOMIAL EXPANSION

well wat i did was OA + AD (AD=BC, since parallelogram) So OA + BC ...and i checked my answers with quiet a few students and found it to be correct

Does anyone remember question No 6? what was the coordinates of C? and what was the distance AC"??1.41 or 3.58?

dont remember ...what were ur coordinates ardon:

 

[farhan29]

haha.. i dont remember the coordinates my friend , thats why i am asking..

 

[obsessedgenius]

what was the vector angle?

 

[ks136]

haha.. i dont remember the coordinates my friend , thats why i am asking..

I THOUGHT U WERE DOUBTFUL

 

[farhan29]

sort of yes..because in here everybody is giving me a different answer so i think i forgot mine. So wanted to be sure

I solved all correctly but I was so nervous yesterday that I forgot to write reason why I took the limit between 16 and 0 for the integration of last question volume of revolution. Will I lose marks?
