kit kat thank you :'')
ok... i got it.. Thanksput DY/DX =0 then solve this and curve equation simultaneously
Thanks A lot!!!let u^2 =x
that means dx/du =2u that means differentiating u^2 woth respect to u
dx= 2u du
next thing is to change limits...
if u^2 =x
when upper limit of x=p^2 then replace x with p^2
u^2 = p^2
new upper limit =p
and since o will remain o
the new limits are p and o
then u have to integrate cos of root of u^2
root will cut the sqr u will get
integral of cos u dx
now look at the third line of this solution u will find dx= 2u du
integral of cosu 2u du for the limit p and 0
integrating by parts
u= 2u dv= cos u
u'=2 v= sinu
2u sin u- integral of 2sin u
2usinu -( -2cosu)
2usinu + 2cos u... apply limits p and 0
2p sinp + 2cosp - ( o +2 cos0)
2psin p +2cosp -2(1)=1 as this is also equal to the area of the shaded region...
2p sinp= 3-2cosp
sinp= 3-2cosp / 2p
wont u be solving all the pprs?guys is 2012 and 2011 all variants enough to know how much is your prep :S
i already have solved 2002 -2009 before 1st of maywont u be solving all the pprs?
Hi-5i already have solved 2002 -2009 before 1st of may
yar i said i solved them i didnt say succesfully to many errors and problemshmm phir pych kia rhe ho?
Part 5 ii again Rutzaba (sorry for tagging, but due to quick response I am really really really glad)
Yess More prayers coming!View attachment 42627
hogaye ye wale or shall i do em?http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Mathematics (9709)/9709_s12_qp_31.pdf

Can anyone explain to me wat the ms is saying for Q10 part iv??! >.<
these cie people cud try making a marking scheme when they are not drunk for a change >_<
this doesnt make any sense
I got the answer 0.906 but all these other values given in the ms seem to b mumbo jumbo to me
pray in returnThanks A lot!!!
I wasn't integrating it by parts :/
Anyways,thanks again
ummm do it ^__^hogaye ye wale or shall i do em?
