Mathematics: Paper Two Predictions

Lucas10101

Would like to see peoples predictions here. There's a lot more on this paper to learn off by heart....if you're doing Trig. anyway, but overall...I think it's the tougher paper...Like with english where most people were spot on....would there be nay likely predictions for this paper...would help people especially me a lot.

I think that a Binomial Calculus question is likely.
The circle proof.

Thanks.

this is meant to be the "difficult" one, in the mocks this was 22 of my 29%

Theres not really any "tricky" questions that can come in paper 2, which means itsn ot really a tricky paper, once you learn it you'll be able to do the questions

______

but i didn't learn it.

trig is lovely, didn't even know what the word meant when i done the JC, got absolutely everything on the paper right, that cockiness was my downfall

Who cares if it's difficult???? STOP discussing that....people want predictions...can people deliver them please?

By 'people' you mean you??

______

i predict probability, trig, the circle and that one with with integration by parts will all come up

Any smart person knows that the amount of predictions that can be made for maths is minimal other than using common sense to know whatll come up based around exam papers.

I learnt maths paper 2 in a day or 2 last year, I messed up paper one and it was suppose to be my good paper. Ended up getting most of paper 2 right, or it seemed right anyway

______

well probability can be a bitch cos you think yoiu have it right, then you dont.

I punt Cosine Rule

Trig Identies as usual.

Difference Eqt

Standard deviation

Normal stuff but with an added twist here and there.

sorry, could somebody show me an example of a binomial calculus question, the name doesn't ring a bell.... thanks.

in relation to standard deviation i found out a shorter way to do it, the box thingy always confused me. this might help some of use.

what you do.

square the five or six numbers that are use to calculate the mean.
add all these numbers (which you have just squared ) up and get the mean of them.

get the mean of the numbers that are on the page ( the numbers you squared) and square it.

minus the smaller number from the bigger number and get the square root of your answer.

this gives you the standard deviation with out doing the box.

an over view:

get the mean of the numbers squared - the mean squared and get the square root of your answer.

if you have any problems wit this just pm me.

cocoa

ok, I think you're wrong but a simple test will tell...:
1,2,3,4,5
mean = 3
standard dev = root10

by your method : 1+4+9+16+25 = 55
mean of squares = 55/5=11 -> 121
121-55=66 !=10...

mean of numbers squared = 11
mean of original numbers = 3
mean of sqrd sqrd - mean sqrd=121-9=112 !=10 ....

Seriously, I don't get it...

It's the Binomial Expansion in Calculus where you use for example the square root of 1+2x and use normal maclaurin to evaluate the general series and that. I haven't seen it on in years. It's the same as Exponential only you differentiate a square root normally in those questions.

I don't really in predictions for Maths (H) however it would be nice to see some predictions from yourself!

.

This was in my first post? Maybe you didn't read the text :rolleyes:

These are the main two I have seen that seem likely as they haven't been up in years and te last few have been there in the last few years repeatedly recently. The circle theorem seems likely for this reason as well.

Erm...from anything else, I can see the Trigonometric Idenities and the proof of the Cosine Rule.

I'm gonna learn it all, in 2.5 days along with biology. **** predictions

Thats the way I did it:D Except I hadn't looked at the paper before the weekend

is the standard deviation of that not route two:eek:

WHich is why hes debunking this way of getting the standard dev.

cocoa

no... more like, which is why you shouldn't do standard deviation in your head....

mean = 3
deviations = 2,1,0,1,2
square = 4,1,0,1,4
add = 10
divide by 5 = 2
root = root2

thanks for spotting the obscene blunder there...

Bluefox21

lol no prob any other tips thanks to this iv just learned circle formula and binomial through maclaurin anything else I should look at?

Binomial through Maclaurin :eek: dear jebus whats that?

Seems the Difference Equation proof is being tipped hotly.

Bluefox21

lol its ok basically prove the expansion its in the back of texts and tests five...

melsman

to prove the perpendicular distance formula looks likely, it hasnt been asked in years, maybe the formula for a tangent to a circle centre (0,0) aswell

Bluefox21

yeah your prob right someone said a proof for the linear transformation was due aswel that would really mess me up!

They are pretty standard anyways so I wouldn't worry too much about them. They usually will give you a hint on how to approach them so it can be pretty easy!
