Maths papers(new format)

[Vin]

hi
i was wondering that are there ny math papers/specimen papers available for the new format of maths paper4..??
i've seen the format from may/june 2009 paper 4 is supposed to be written in the paper itself (earlier papers had the system of writing on a separate sheet...we've been givn m/j 09 n oct/nov 09 as our preliminary exam practice..)
i jus' thought there might be more papers available of this format of the paper...but couldn't find them

It doesnt make a difference whether you do it in the paper or not. Honestly the new format has been introduced to improve presentation. On the CIE main website there is a specimen paper (new format) of the paper 4 that was used in 2007.

yup my math teacher told the sme thing..

Q..Find any expression, using 1, 2, 3 and n exactly once, which will always be greater than 1 for any
value of n.

If you can use n^2,

(n - 3)^2,

n^2 + 3*1,

etc.

n+1(3-2)

When n <= -1?

I think i hav it, wait a second.

The paper

[holtadit]

If you can use n^2,

(n - 3)^2,

n^2 + 3*1,

etc.

When n <= -1?

-1+1(3-2) = 0 Hence 0 is one greater than -1 . Whats the problem ?

[Saladin]

-1+1(3-2) = 0 Hence 0 is one greater than -1 . Whats the problem ?

it said greater than 1, not negative 1.



Try it with all numbers, it will work.

I just realised he wanted a formula that would give an answer tht is greater than 1

I thought he wanted a formula that would give an answer 1 greater than the value of n


Sorry people, Ari just messed up.... my bad

Sorry i cant answer now, I have to go for lunch.

Just hang in there someone will help you.

sure ..

Use the pic.

a = all trig functions are positive in this quadrant

s = only sine is positive in this quadrant

t= only sine is positive in this quadrant

c= only sine is positive in this quadrant

so if sine and cos are negative they must be in between 180 and 270.
