Maths C2 discussion!! :)

[IGCSE Abdullah]

i think grade boundary would be 80% A grafe and 70% B and going DoWn!!!!!

 

[IGCSE Abdullah]

Eq of circle

(x+5)^2 + (y-9)^2 =25

DAMNit!

 

[cardude456]

DAMNit!

What did you put......???

 

[Cell_ar]

For trig i got 56.3 for the tan one (1 solution), and for the other one i got 72,144,216,288.

I got that too

some of my answers
area garden - 262.5
perimeter - 80.2
area graph - 148/3
minimum point - 4,-28
a^5/8

oh no ! the minimum point did a stupid mistake in last steps of algebra got 1/4 thus y is wrong

 

[ahmed soliman]

stationary point is 4 (because x^(3/2) = 8 so x=4 )
area of graph is 128/3 +20/3( because area of second integral can never be negative)
equation of trigonometry solved by completing square but i do not remember answer then 360 - ans
garden qustion : there was someting of 252.5 or something like that )
tan i got something of 93.3 but dont remember if there was another value
perimeter was arc length + 23 +12 + the other side found by cosine rule

and also x=-4!!

 

[Hamzeh S]

The g(Y) was y=1 and y=0.31

0.37

yup except i made a mistake in stationary point wrote x^-3/2 not 3/2 dunno y hhaha so i got y wrong also how many marks for that question?

 

[Saad96]

0.37

Yeah I think it was 0.37 but it was also 1 didn't they say values???

 

[ahmed soliman]

how many angles were in cosine did anyone get 2 angles 36 and 324
who here solved equation by completing square ?

 

[Manasa]

wat were the answrs or binomial exp?...

 

[Alla' Abu-Sultaneh]

Yeah I think it was 0.37 but it was also 1 didn't they say values???

it was 1 also

 

[WaterFox]

Guys, it would be better if you didn't discuss this exam until midnight GMT/UTC because the majority of countries in the world could have access to this paper (because it's Edexcel), so they could see the answers and thus the grade boundaries will be higher...

 

[ahmed soliman]

binomial had like 5 values one was I think 16 216 216 81 dont remember actually

 

[Hamzeh S]

Yeah I think it was 0.37 but it was also 1 didn't they say values???

and 1 yah

question had about 13 marks not sure though but if u differentiated correctly and equated the gradient to 0 u will definetly get marks and remember we have the error carried forward by our side so never worry

not 13 marks lol it was 4 or 5 for this part

 

[saba1996]

the paper was good i guess, i left 2 Qs though....
