Maths paper 32

[thunderbolt]

Since everyone's talking about paper 4,lets create a thread for paper 3. How did you guys find it??lets share answers...personally thought it was average

 

[Ola Khalil]

thought it was very tricky.

 

[thunderbolt]

what questions?

 

[Ola Khalil]

last page and first page were quite easy..everything else in the middle...agh.
the second last page..the one with the wheel..that question was tricky.
even the exchange rate question was weird.

 

[thunderbolt]

the exchange rate one i think u just divide..the loci one was messed up ..hoow did urz look like?did it look like an X by any chance?

 

[AishaAbdulhakim]

I personally think it was amazingg, easier than other past papers atleast. I didnt have time to finish 3 questions (finding angle of the prism using trignometry, finding the poles needed for bicycle wheel and the nth term rule) which were all together 9 marks.. other than that Im sure of all the other answers. and the locus was goood, the outcome was a trapezium not X (that's why they asked, whats the mathematical term - which was trapezium), did you do that?

Hope the threshold isnt high >.< ...

 

[thunderbolt]

noooo i wrote kite..wat were u supposed to do for the perpendicular bisector....the nth term was ok i guess i hope i got the right answer....wat did u get for grad..was it minus 0.5 or something like that??...also wat were u supposed to do for the maximum thing...the one about the upper bound question...also wat did u get for the bearing..

Perpendicular bisector was the lines between A and B to make both equidistant (for example look at the picture). and what grad? remind me of the question, sorry >.< and for the upper bound, just add 5.. (for example upper bound of 45 is 50 and lower bound is 40.) and bearing, B from A was 037 and the distance in km was 50 km(i dont remember exactly) since 1cm=10km.. so 5x10=50km

yea the upper bound question is ok,im talking about the maximum question one??....and for gradient im talking about the qn after the graph we were supposed to draw??

i dont remember the maximum question >.< ! and the gradient was 2
equation= y=2x+3

 

[thunderbolt]

will i get a mark for getting the y-intercept right?..also it went to the left,that means it must be a negative something

 

[MaramHZ]

It was y=-2x+3
The upper bound I did it 45.5, because If i made it 50 it would be to the nearest 10 kilograms i think
The shape in the locus indeed was a trapezium, and we had to shad the circle inside E and leave the part that was in a, it looked like a circle with a bite taken out of it.
But that wheel spokes question, i think I screwed that up real bad..

Yeah I think you're right. but if one of us is wrong, we wont get a mark for the y-intercept cause the question is 1 mark anyways >.<

it was 3 marks man...i think we'll both get something

Yeaah I did exact thing for the locus part but the upper bound, i wrote 50 and i wrote 2x+3 >.< ahhhh negative. annoying

I hope so :'c

for the upper bound question,they said to the nearest(put a figure,wat i did was i divided that figure by 2,then added that answer to for example if it said calculate 3554 upper bound to the nearest 50,i didvided 50 by 2 and added it to 3554...just an example but yea thats how i did that question,for the wheel spokes one i was also lost..also when u want t get diameter do u divide or multiply??
