Who said that ??? -_-

 

[Suchal Riaz]

hmmmm but it will tend to give out more questions... how was the paper?

idk can't say anything now. it was not bad. the good thing is that even if we lose 10 marks we get an A
i messed question number 6. but corrected it after time was over. idk if my final answer is correct. still i will be getting more than 45/50

Everyone seemed really worried abt this paper

everyone is worried about every paper even if it is easy and they are well prepared.

All of us are having internet ...u must have misunderstood

but there seemed to e extra tension here

tension was in almost every question of today's paper
( i mean the force tension, and this is a pun )

i do get that much physics

ffc me mushkil hoti hy na?

oh yeah he asked me not to tell u lololol

i just cleared that it was pun otherwise you could think that i had tension because of difficulty of all question.

 

[Hassan Ali Abid]

oh yeah he asked me not to tell u lololol

How was ur mathematics P42 ???

 

[daredevil]

I am getting a=4
everything else is correct... the whole question is correct except for this stupid little thing...

I had an equation from P(-1/2) => a=-2b-2

got the correct value for b when I put this value of a in the other equation but when i put b=-3 in this to find a after that ... i get 4 instead of -4!! >__<

heres the mistake
the eq will be a=2b+2

 

[daredevil]

heres the mistake
the eq will be a=2b+2

so how come b is correct even though i used -2b-2 to calculate that too??

 

[Rutzaba]

a= 2b+2
-16+20 -2a +b=9
b-2a=5 substituting...
b-2(2b+2)=5
b-4b -4=5
-3b=1
b=-3

 

[Rutzaba]

i dunno but the eq is wrong...
see if bracket hai aur uspe power minus hai to wo minus hi rahe ga
aur power even ho to plus hojata hai
