∫ 2/ u(4-u)Please help! This paper http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Mathematics (9709)/9709_s07_qp_3.pdf
Question 5 part 2!
And question 8?
How do we do them?
its not hard on paper... computer freaks everyone out
https://twitter.com/TRm94/status/332938326950678528/photo/1how can i solve question 10 omggg! someone pls help

Thank you so much for ur help- but, umm... u solved the wrong question. :/∫ 2/ u(4-u)
by partial fractions
A/ u + B/ 4-u
((((A(4-u) +B(u)))) / u(4-u)
4A -Au +Bu
compare with 2/ u(4-u)
the denominator eliminates... and we have two equations
a-b=0 since there is no term in u---i
4A =2 the term without variable
A= 1/2
b=1/2
then ∫ 1/2(u) + 1/2(4-u) for the limits 2 and 1
1/2 ln u + 1/2 ln (4-u)
1/2 ln ( u +(4-u)(-1)) note that the -1 is the differential of 4-u
minus means to divide in log
so 1/2 ln ( u/ (4-u))
out limits 2 and 1
1/2 ln (2/4-2) -1/2 ln (1/4-1)
1/2ln 1 - 1/2 ln 1/3 note that ln 1=0
0 -1/2 ln 1/3
-1/2 ln (3^-1) by log propery the power would come down
-(-1/2 ) ln 3
1/2 ln 3
sorry abt the complex numbers ive completely forgotten em ... dun frgt to pray fr me
loool lemme try this oneThank you so much for ur help- but, umm... u solved the wrong question. :/
I don't know how to do the integration of question 5.

Question 5 part 2!
And question 8?
How do we do them?
I cant get the argument of u^2. And yeah part 2. Thank you!Q8.. you know how to find the modulus and argument ?
Are you asking about the ii) part ?
and im not awesome -_-
You'll like A2 Physics (hopefully)... me and my friend found As hard too and this year, the As part seems so easy and A2 is interesting too, except the applications part. Insha'Allah you'll find it good and easy!HEY YOU ARE TOO AWESOME .. you are just being modest
Well I hope P3 is easy.. cuz next year Physics is going to kill me.. I found AS physics hard.. what will A2 Physics do to me -,-

p3 if you get a good teacher 6months are enuff fr prep... obv u go out of practice very easily in maths :/
I cant get the argument of u^2. And yeah part 2. Thank you!
The argument of u is -3π/4 in the ms and the argument of u^2 is π/2...Argument of u^2 is found by multiplying the arg(u) by 2.
The picture is a bit unclear
But you have to mark the points u and u^2.. then make a perpendicular bisector of the line joining these two points.
And make a circle with centre (0,0) and radius 2.
Shade the part to the right of the bisector, and inside the circle
