I'm quite prepared although nervous!!!
The only thing I can't get my head round is coordinate geomentry which is a shame as it seems to come up a lot!!! Any tips??? :smile:

They're both in the morning, right?
So do we get a break in between? (is this different from school to school?)

I think it varies.

can anyone explain this Question to me :| i cant remember anythingggg on sequencessss :|

(a) Prove that the sum of the first n positive integers is given by
1/2 n(n + 1).

(b) Hence, find the sum of

(i) the integers from 100 to 200 inclusive,
(ii) the integers between 300 to 600 inclusive which are divisible by 3.

a)
Positive integers:
Sn=1+2+3......+n
reverse it
Sn=n+(n-1)......+1

Add them up
2Sn=(n+1)+(n+1).....+(n+1)
You have n of them so
2Sn=n(n+1)
Sn=n/2(n+1)

i) 100+101......199+200
a=100 l=200 d=1
l=a+(n-1)d
200=100+n-1
n=101
Sn=101/2(100+200)
Sn=15150

ii) 300+303+309.....+597+600
a=300 l=600 d=3

l=a+(n-1)d
600=300+3n-3
3n=303
n=101

Sn=101/2(300+600)
Sn=45450

Hope it helped :smile:

If you do every question in the Heinemann book surely you should be on the way to an A? How many past papers are you going to do?

does anyone think any proofs will come up for c1/c2? what topics haven't come up recently? perhaps sigmas anyone else have any ideas?

Argh... I was going to do all the Solomon Papers...
ended up doing nothing...
:s-smilie:

Anyone has C2 exam as well?

I've done up to D for C1 so far. Some of the questions are weiiird and some are like questions Edexcel would never even think of. Edexcel.

Yep, I got a letter saying there was an exam clash so I have to sit C1 then C2. Three hours of Maths fun :biggrin:

.

Hmm.. I'm dreading a stupid arithmetic series question that makes u₁ year 13 and they ask when some stupid person stops receiving their allowance. Hmm... if there's a proving the sum of an arithmetic series formula question then yay!

C1 and C2. Where I am sitting them, we get a five minute break.

I am quite confident... both are easy, but C1 compared to C2 is really, really a piece of cake.
I am expecting to get 90%+, in C1 at least.

APs, GPs and circles are the things I have to work more on, but the rest it's probably done.
I'll do some past papers (two or three) and that will be it. :biggrin:

i have did all the review exercises and pastpapers.
i have a hope that i will get atleast A grade
my only problem is careless mistakes.
Hope they give a easy one......... :smile:

Can anyone tell me how standard edexcel papers are? cause i am new to this syllabus

Does any one have the mark schemes for the 2010 papers?

If not, people should start posting any questions from the 2010 papers they are unsure about so that we can clear up any uncertainties.
Would be next best thing to the mark schemes.

MyMaths.co.uk is a really good website for coordinate geometry (that I find) see if your school has a login and go through a coordinate geometry question and look at the mark scheme - for how to get EVERY single mark :smile:

Hope this helps.

I'm pretty confident, me and friends have taken it upon ourselves to do speed runs of C1, my personal best is 68/75 in 44 minutes :P
Feeling much better about than C2....

y2 - y1 / x2 - x1 = gradient
OR
dy/dx = gradient (when X values are inserted into gradient function)
^ is for the gradient

Area = y2-y1 * x2-x1 / 2

AB^2 = b^2 + a^2 <---- For finding length of AB^2, then square root.
(b = y2 - y1) (a = x2 - x1)
Pythagarous Theorem ^

That's all I know for co-ordinate geometry... hope that's all that appears in the test for it!
