take mid value as mid value of class width.yes,but to use the eq we first hav to find the mid values of x,thenfx divided by f.dont u remember
i'm not talkin bout coded mean n variance formula

yesssstake mid value as mid value of class width.
How did u solve question 1....I kinda felt it really toughso how was paper 62
post ur answers to confirm
q1 1c1 * 1c1 * 48c43??in q1How did u solve question 1....I kinda felt it really tough
Yes I did the same...hope we get it correct....btw how did u solve the 7th binomial question...q1 1c1 * 1c1 * 48c43??in q1
which 1Yes I did the same...hope we get it correct....btw how did u solve the 7th binomial question...
yeah it was a binomial the 1st partYes I did the same...hope we get it correct....btw how did u solve the 7th binomial question...
its right.q1 1c1 * 1c1 * 48c43??in q1
second part ...buddy......second question second part......can u tell me how u solve itwhich 1
replace f(x) in g(x)http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Mathematics (9709)/9709_w08_qp_1.pdf

Question 10 (ii)
Please avoid solving it using differentiation. I haven't learnt it yet.
I don't get the gf (x) part. And why do we have to use the method; 'completing the square?
Thanks.replace f(x) in g(x)
do d^2/dx^2 to show tht maximum is 9
Let me show him answer in detail. Wait.replace f(x) in g(x)
do d^2/dx^2 to show tht maximum is 9

Oh thank you for explaining rookz didu.replace f(x) in g(x)
complete the square
equate the bracket u get from completing square to zero. ull get value of x
the value after the braket will be the value of y
(x,y) will be turning poitn so maximum point
like a(x-b)+c
x=b
y=c
max point (x,c)
its ok kiddoOh thank you for explaining rookz didu.
I was about to start.
Do we do double differentiation?replace f(x) in g(x)
do d^2/dx^2 to show tht maximum is 9
yeah double differenciate to show max n minDo we do double differentiation?
