Does anyone remember the indices question??????

 

[Luzzo95]

not really , but the second one was (x^3/64)^2/3
My answer was x^2/16

 

[Arcticmonkey]

my answer was (x^2 / 2^4)

 

[burndtjamb]

I think the answer to the first one was something like 4x^-24

Does anyone remember how many marks the vector question was?

 

[tripleA95]

Was this part of Paper 22 or 21?

22

 

[burndtjamb]

Stuff I said was 22. Did you do 21?

 

[Luzzo95]

Does anyone remember how many marks the vector question was?

both was for 4 - 5 marks

There's no way that on a paper two they would devote 10 marks to a question like that :O

 

[Arcticmonkey]

I thought both were for 3 marks :?

I said both not each

Yeah maybe it was for 3 because what i can remember the first one was for 1 mark

and the second for 2 or 3.

the first anwer was 1/2a - 1/2 c
and the second was 3/4 a + 3/4 c

That sounds more likely . I made a stupid mistake on the second part of the question so hopefully I'll only lose 1-2 marks.

 

[Arcticmonkey]

ye the midpoint was half of the the lines that joined above it

 

[Luzzo95]

No they said the position vector and thats what most students forget.
you have to go from the origin to the point which you were talking about which is half of BT i guess

 

[haochen]

my answer is the same as Luzzo95

 

[WayneRooney10]

the indices questions were 2 marks each. The vector questions were also 2 marks each. What did you get for brunei and euro question??? I got Euro.

 

[tripleA95]

Stuff I said was 22. Did you do 21?

No but I don't remember that question.

 

[haochen]

WayneRooney it is already discussed on other thread
but i choose euro my explanation is on other thread

 

[Luzzo95]

My answer was EURO , and i guess its the correct one.

What about the very first question , i got 53.1 which im pretty sure of it.

 

[haochen]

me too I got 53.1...
