igcse math paper 2

[beewhiz997]

2 lines of symmetry was "I"
n rotational symmetry was "N"

i got that but some ppl r saying it was N and I for d second part...

 

[Lostsoul]

awesome! hope u do well inshallah

Inshallah, all of us

pls tell me wat da hell is a thershold thingy majing??

the curve the grade needed for an A or a B or a c ...etc it varies each year according to the students preformance

 

[Hamzeh S]

Whats An "A" in math usually from?

paper 2 last 3 years was in the late 50's

 

[Maroon 5]

x invariant and yes 1.25

it wasnt 1.25 coz they ddnt ask fr the gradent they asked fr the value of k whch was twice y ... it wud be the gradient if y was 1

Aslam-o-Alikum every body . i have noticed that every student was worried about the the equation of // lines ( 14y=xxxx ) but one thing is clear that gradient of // lines is always same so k was not even 1.25 or 2.25 . i m dame sure about my theory.

 

[naib]

i got area as 10 and bearing as 210

ur area is wrong bec formula was 1/2 a.b sin Q = .5 x 8x6 sin150 = 30

Anybody knows when the marking scheme or even only the paper will get uploaded on the internet?

 

[nehaloo]

it will be uploaded after the results....

u aint wrong but do u remember that any equation of line shud be y=mx+c
so make y da subject of da formula n then u'll see one one of them is (sth/4) n da other is (sth/2)
n den 5/4 = 1.25
here comes da question is it 1.25 o do i hav to multiply it by 2 ??
Tu as compris??
(sorry just felt like speakin french)

 

[nehaloo]

actually my opinion is tht it doesn't have to be multiplied bcoz if u multiply then u will change the gradient and they r parallel!

Hey! I did in another way and i got the answer 2.5
it doesnt involve multiplying 1.25 or anything

 

[Hamzeh S]

hey wat about O?

o has infinite symmetries

 

[Hamzeh S]

2 marks for the whole questions

me too , i didnt get it as 1.25 i just felt i have failed half of the exam after reading what most people got here

wat was da answer 4 taxi question?

i got the one up as 1.2 km and the nightfair is 9 * 30/100 = 2.7
so 9+2.7=$11.7

 

[Razo513]

ur area is wrong bec formula was 1/2 a.b sin Q = .5 x 8x6 sin150 = 30

the answer is right ... check again

 

[Anny Amin]

It was great actually! Didn't expect it to come that good xD
Plus, it was 19 questions only not 22 =D
I'm just having a fear from paper 4, rabena yostor :3

 

[areebaization]

wat was da answer 4 taxi question?

i got
a) 15 km
b) $11.7
tell me ur answers
