Maths paper 4 discusssion

[adityar]

Wasn't the inequality 1 < n <= 5 ??????

 

[Keeemoman]

Yup

 

[Dooouuu]

plz the answer of the last question was 0.5 and 1.5 ??!!.....and what about the HCF and LCM ?! I did it HCF= 12 and LCM = 2

I thought the paper was by far the easiest one I had done. It was easier than the previous years, but there was one part that made me stuck. It was much easier than a paper from 2000, which I struggled a lot.

It was hard dude. What did u get for the bearings?

 

[lolostar95]

omg i did really a silly mistake in the mensuration question .... i didnt find the perpindicular hieght of the large cone ...do u think that i am gonna all the mark or only 1 and the last question it was no hard but sooooo tricky i hope that i am gonna do good ... but i believe that the curve is gonna be soooooooo low ... I hope so.....

guys remember the cumulative frequency thing?
the first point is past 0 , so were we supposed to leave the start hanging in mid air... or plot it to (0,0)

I sure do hope so lolostar

I think it was relatively easy compared to past Paper 4s I've done.
Last question was a pain... but it's just deriving simultaneous equations out from info given
Overall, quite good.

Its was 1 < n <= 5

I made it from (0,0)

How did you guys find the surface area for that pyramid with a hexagon base??

 

[soccerprinc3]

get the area of the triangle (0.5xbxh) then times it by 6. Then get the area of the trapezium 0.5(a+b)h and times it by 2. finally add the two answers!
well thats what i did, not completely sure if its right though

 

[Aahmsil]

Follow the rules !!!

Guys, no paper discussion before 24 hours !!!

Follow the rules or else risk getting warned !!!

Somebody is eventually going to find out.

Hope all 'o' y'all know the rules.

 

[Keeemoman]

Thats What I said in the beginning of the discussion.
We can also say how was the paper but eplain what happened in details

 

[LoliSabae]

Hello,

Well, I just want to know Is it a problem like will the examiner not check the question??

For example, in this math paper 4 exam.. I omitted my working in the last sequence question then the invigilator told me to write the working at the last page??
I am just worried! :S

Thanks in advance.

wat do i get if i scroe 45 for paper 2 and 80 for p4

 

[WayneRooney10]

wat do i get if i scroe 45 for paper 2 and 80 for p4

you will be very lucky will you get an A. Is possible, but is improbable.

I did Paper 42, and the pyramid had a hexagonal base with 6 Isosceles triangles.

So it was (1/2 x base x height x 6) + (1/2 x radius^2 x Sin 60 x 6)

 

[haochen]

the answer for HCF is 12
and LCM i think 2

pyramid i calculate the hexagon by the triangle * 6
then the triangle of the side * somthing forgot

and add them up

hope it is correct
