MATH PAPER 1 Discussion

[AlteredTuning]

how many marks was this question, i mean the simultaneous equation sum????

 

[Mobeen]

how many marks did enlargement carried?

i think it ws 2 ..

 

[momen]

GUYS DID YOU TOOK TANGENT FROM "16s''

answer plz

No we had to take the tangent at 18s as was stated in the question

yes sorry 18s

 

[h_jay]

wasnt the perimeter ans like 1^(pie)^r/3 and area 1^(pie)^r^r/6?

 

[momen]

100% accurate tangent gradient ------> 0.75 (they might consider the answer correct if it is in the range 0.7--0.8)
what was answer to the PERIMETER of SECTOR??? i know but what did you guys write?

these would be correct
0.65
0.66
0.67
0.68
0.69
0.70
0.71
0.72
0.73
0.74
0.75

 

[shahoo]

i done it rong :|

 

[momen]

you could write pie 22/7 also

 

[shahoo]

can u tell me the formula for perimeter of sector plz

 

[Momin Aziz]

I was short of time, had only 15 mins and was on question 20... I went through the Transformation Quickly and forgot to do the Enlargement .... Finished the Paper at the LAST MOMENT... like only 45 seconds were left...

 

[h_jay]

perimeter of a sector - angle^2^3.142^r/360

 

[momen]

if you have done it using pie then .!

1/6 (pie)(r) + (2r)

if you have done by taking pie= 22/7 then

11/21 (r) +(2r)

 

[Mobeen]

momen i dont think we were alowed to use pie as 22/7 .. cuz the question said tht find area/perimeter in terms of (pie) and r .. he actualy meant we had to use both symbols in our answers ..

 

[allthatglitters16]

yea but in previous markschemes even if it says do it in pi, the examiner acepts 22/7 or 3.142 etc

 

[BILALrox01]

yea but in previous markschemes even if it says do it in pi, the examiner acepts 22/7 or 3.142 etc

They have been known to change markschemes too dude.
\one year they accept one response another they dont accept it
Foe eg in chem one ear they accepted CO to cause suffocationnext year they rejected nd accepted only doesnt allow O to react withRBCz,
Anther thing never uz 22/7 in o lvl papers
they allot one mark for a coorect response A1
sometimes using 22/7 ur answer comes out of range

thnxx man..!!

if you have done it using pie then .!

1/6 (pie)(r) + (2r)

if you have done by taking pie= 22/7 then

11/21 (r) +(2r)

It was to be

1/6*2 (pie)(r) + (2r)

and you could not use the value of pi as answer was to be given in its terms

 

[M.Usman Khan]

as the specifically said in terms of pi so by using the pi value u will lose a ark as u r going against the question.

 

[beststriker]

if you have done it using pie then .!

1/6 (pie)(r) + (2r)

if you have done by taking pie= 22/7 then

11/21 (r) +(2r)

It was to be

1/6*2 (pie)(r) + (2r)

and you could not use the value of pi as answer was to be given in its terms

i wrote it as 1/3 (pie)(r) + 2r. i multiplied 1/6 by 2. it would be acceptable.....

 

[Mobeen]

beststriker u just did simplification ,, thts all .. it wont lose marks .. and wasnt the answer required to be given in its simplest forms .. ?

 

[beststriker]

ya thnx......
