igcse math paper 2

[shefali]

i got -1.3

 

[nehaloo]

almost near i think tht the range will include both of them :/
and the inquality question was the 4 included too?

 

[Shady Omar]

I got -1.12 for the gradient :/

 

[Shady Omar]

Yeah the numbers for the inequality were 1,2,3,4

How was your exam guys paper 22 ? i think it was easy but some functions were hard what was the gradient of the parralel lines and the inverse of f?

the gradient with the tangent one i got -1.6 , i didnt no this one with parallel and for functions it was cube root with x-5 and then + 2 sumthing like that , what did u guys get for the trigonometry one did u get around 230?

 

[kareem]

Yeah the numbers for the inequality were 1,2,3,4

0,1,2,3,4 actually , it said integers you still get 2 marks i think

 

[shefali]

i got area as 10 and bearing as 210

 

[kareem]

i got the gradient abt -1.53 wt abt u?? hw much did u get it?

I hope paper4 is easy :s

paper 4 will include vectors symmetry probability and maybe a little statistics last page sequences for sure maybe a little transformation and some graphing , areas and volumes and geomtry and mensuration hopefully it will be easy and i hope for a low grade thershold (curve)

theres 99.9% chance for transformations it always comes paper 4 and also graphs

I Got -1.56

No because 0 isnt a positive integer

 

[kareem]

same , whatd u gget for the one thats trigonometry with the height , was it around 230?

 

[kareem]

No because 0 isnt a positive integer

it counts i think google it

 

[shefali]

since it said positive i dont think 0 was needed as 0 is not positive nor negative

 

[kareem]

No because 0 isnt a positive integer

i got 282 i think yes (tan whatever + given height)

 

[kareem]

i got 282 i think yes (tan whatever + given height)

i did with cosine and got 230

Wikipedia: "Zero is defined as neither negative nor positive."

And what if I wrote.. 1<x<4.5 for the inequalities??

 

[Lost_Life]

um there was a question in my paper saying:
find the k in these equations of lines:
5x+4y=10
14=2y-kx

What i did is i simply rearranged them, then i put (-5) as k because it is a parallel line therefore gradients are equal right????

Yeah its 282 and then you have to add 170 to get the final answer.
