[Zuhsid]

It was good.... but quite a few questions were tricky..... especially the extension one in p2..... Don't know if i did it right...!!!

 

[Kamihus]

So here are some answers for Maths 12
They are in order but some r missing (don't remember all the question numbers)

The answer for the cumulative f curve was 16. Where's that?

 

[Kamihus]

what were the total values that you wrote? i forgot that 1

Last question: (d)(i) 3x^2-6 (ii)3 +-underroot6

Are u sure those rotation vertices are correct?

 

[Saad Mughal]

Are u sure those rotation vertices are correct?

Yes, the figure went ABOVE the original A triangle NOT BELOW.

 

[Snowysangel]

what were the total values that you wrote? i forgot that 1

Total values? I just remember that part if the question...the rest is a blank

 

[Snowysangel]

Yes, the figure went ABOVE the original A triangle NOT BELOW.

Really? Bleh I think I placed the protractor at the wrong end or something :S

 

[Saad Mughal]

Really? Bleh I think I placed the protractor at the wrong end or something :S

BELOW would be anticlockwise. ABOVE would be clockwise.

 

[Kamihus]

Total values? I just remember that part if the question...the rest is a blank

i mean from what value did u subtract the answer from

 

[Snowysangel]

i mean from what value did u subtract the answer from

80

 

[Kamihus]

80

ok but still cant remember the question
i think you're right it was somewhere there

Are you like 100% sure for all answers.....??

 

[Kamihus]

Are you like 100% sure for all answers.....??

i think so but if u find any mistakes plz do tell i hope there aren't any

 

[areela hassan]

n

Really? Bleh I think I placed the protractor at the wrong end or something :S

nope below is clockwise i remember

 

[Zuhsid]

Chose the wrong answer in one of the MCQs too (from what i know)... the one in which the filament breaks.....

 

[Hamza Hameed Khan]

In the loci question of math paper 1 the region to be shared was the top right one or left one ? I donot remember the position of point A...
And the alphabets representing inequalities were f and e right. ?????

 

[Saad Mughal]

Yes and yes.

 

[Hamza Hameed Khan]

Yes and yes.

So was it the top right part or the left part to be shaded ?
