[karthik]

Karthik, I do IGCSE's, I did my 0580 Maths Paper 2 exactly 24 hours ago now

Hmmm u should definetly be different zone

 

[maths maldives]

what was the coordinates for the last question's (A) ?
is it (1,9)

Oh no dear its (1,4) btw are u really frm maldives?

hey karthik ! r u doing 21,22 or 23 ?

22

This is the answer. hope u like it

can u post all the inequalities given

 

[karthik]

can u post all the inequalities given

y=2 y=2x y+x=6
equation
r>y=2 r>y+x=6 r<y=2x

Hey karthik! What was the answer you got for the angles.. There was that sort of a triangle with a circle right!

 

[Dracula95]

Tch Tch.......check again i gave 22 and the inequalities answer was in the top right corner......see that y is less than or equal to 2x.......this is only possible in the top right corner. Trick question....made the same mistake bt in rechecking i corrected it.

 

[jazzangel16]

Does anyone remember the exact inequalities?

Guys, the order of rotational symmetry was one and the lines of symmetry were zero.
the region labelled as R by karthik in the attachment given is wrong. it was on the top right hand side.
is 0.00660 equal to two significant figures?

 

[jazzangel16]

Isnt it three significant figures now?? 0.0066 is 2 significant fiqures

 

[angelcharms]

ma paper was grreat! alhamdulillah!!

 

[urvesh]

my paper 2 was not soo good!! i went wrong in the identity marix, and 2 more questions.

you think i would still be able to get an A??

please i'm very scared!!!! help me out!

What was the answer for J = mu - mv?? I wrote - J/v-u = m (changing the subject of the formula)

it was 0.0066
yes, R was on the top right hand side
There were 0 lines of symmetry
But the order of rotational symmetry was 5 right?

I gave 22 second variant

Dude mine wasnt wrong ... i did a different varien paper and the symentry answer for me/us was 5 and 0 ... we got a flower and star for the symetry wat abt u?

Yes u can still get A but if u did whole series of question wrong u can even end up in C or D
