MATHEMATICS PAPER 1 Discussion

[Depletion]

hey guyss..for the vector question>>
k was "1/4"???
and the special type of quadrilateral was trapezium? right?? :shock: :shock: :shock: :shock:
ive gor probbs on the question on the lower bound and upper!??? :idea: :idea: :idea: :idea: :idea: :arrow: :x

 

[usama1993]

HEy gyuz, hOw was ur paper?

Mine went pretty well..

What was ur ans for the last question? [radius]

mine radius was 7.5cm


what about u ?????????
and what about the question which asked the special name for SQUARE OF 89 ????????

its irrational number!!! :mrgreen: :mrgreen: :mrgreen:

thank GOD i did it right

my value of k was 1/3....
but the quadrilateral was TRAPEZIUM according to me too

 

[usama1993]

I got 8.5 cm as well for the radius.

@usama Did you do the same paper as us? Because i remember the question being "What is the special name for the Square root of 61?"

are there any different papers too ????????///

i clearly rember it as the square root of 89 :?

 

[usama1993]

hey guys,
what is the answer for the speed-time graph??First part i got 30 S..
and also for the triangle there you are asked to find AC and cos DAC???
For AC i got 12.5cm and for cosDAC i got -7/25...

is it good?????

but i got 30 seconds each for both the part of SPEED TIME GRAPH question

 

[usama1993]

Yeah i got the same answers as you for both questions.

For the last part of the speed time graph question, i think i got 110 s.

And you?

mine was 30 sec

 

[usama1993]

You find the length of one arc = (8O/360) x 2 x pi x r
= (4/3) r

Multiply by 3 to obtain the total length of the 3 arcs = 4r

There are 6 radii in total so you add them up to the arcs to find the total length of wire.

6r + 4r = 85 cm

10r = 85

r= (85/10)
= 8.5 cm

you are wrong jani....
the angle was 40 degree b/w arc lenght....
so u have to use 40/360 not 80/360

 

[usama1993]

total length of wire given was 60cm. my radius was 7.5cm.. and i used 40/360 instead of 80 , because it was the circumference of the 40 degree sector.

right !!!!!!!!!!!!!!!!!!!!!

 

[jess$$]

can someone tell me the answers for the question about temperature first and second part..

plzzzzzz///

 

[Depletion]

mayB w've got differen papers.. but mine is in which the angle inside the sector was 80 and that outside was 40...
so i agree withe pals??
:
:
dnt u worry maybe uve done a different paper!!
which country r u ???

which country r u ???

are there different papers within pakistan too ???????

 

[usama1993]

can someone tell me the answers for the question about temperature first and second part..

plzzzzzz///

the first part...we have to find the difference b/w highest and ;lowest teamperature...
in the second...we have to find the no of temperatures that lie b/w -1.5 C and 3.5 C

 

[Depletion]

mayB w've got differen papers.. but mine is in which the angle inside the sector was 80 and that outside was 40...

mayB>..
because in my paper..!(from mauritius)..the unit (Rs) was used for money!!...
so without any doubt cambridge has set different type papers but mostly of the same questions in different countries!!!
correct me if im wrong!!!

 

[Pals_1010]

Yup I think Depletion is right.

Because i remember my values in the question very well.

Ummm the setting of the question seems the same. Cambridge only changed the values in it.

 

[Pals_1010]

@ usama

I got 30 seconds as well from calculations but shouldn't you add it to the 80 seconds to get 110 seconds?

 

[alay]

does anyone remember their answer to the question abt the integer coordinates in the triangle?

 

[bamteck]

U can either choose 40 or 80 for the angle of sector !

 

[Depletion]

does anyone remember their answer to the question abt the integer coordinates in the triangle?

(4,4) ???idno

 

[alay]

wasnt it (3,5)?

i dont know pals...
please guide me ;;;;
I just worte 30 second
