Same method here again bruh ... It will be useful if you can remember this formula (it's not given in the formula sheet) :
You saved me, I also did silly mistake..Same method here again bruh ... It will be useful if you can remember this formula (it's not given in the formula sheet) :
(1+x)^-1 = 1 - (x) + (x)^2 - (x)^3
Saves a lot of time and effort than the original one, and it's what I've used in solving these problems.
Messy, but understandable right?
Savior B|You saved me, I also did silly mistake..
I hope I will score full marks, only this was my problem, rest other is as easy as piece of a cake. Moreover its as easy to say as binomial expansion, its just one silly mistakes can cost u many marks.. xD
I will tell u my marks afternoon.

piece of cake? really bro? cool ... i make mistakes in vectors and stuff ... prolly cuz i've only done 2 to 3 papers so far
Yeah sure do
Paper was really damn easy, I think I made a mistake in binomial expansion xD That's it. As expected... completed paper in just 45 mins..
Vectors are really easy to solve, just jot down all the concepts in one piece of a paper, and revise it everytime u come through that paper. And then see where u are making the mistakes in vector questions and work on it. Yes I also use to do mistakes till my 3 to 5 papers. But now, I have made my weak points to be strong points.Savior B|

Yeah sure do
Similarly do this with any conceptual questions. ^_^ 
So yeah ... not as easy as just saying 'binomial expansion'
This was the question, can u please show me the working of it?
uhuh ... thanks man! will try to do but imma be lazy :/Vectors are really easy to solve, just jot down all the concepts in one piece of a paper, and revise it everytime u come through that paper.

I think this is O level stuff? Not able to remember how to do this ... you can maybe post it in the IG threads here?Repost: can someone help me with the last two problems? its a little urgent, would be much appreciated
Sorry for the late reply! I believe you answered this?This was the same type of question you had asked me to do binomial expansion in remember?
Well, I can't believe I'm getting it wrong again! So frustrating.
nehaoscar please once again?
YeahSo yeah ... not as easy as just saying 'binomial expansion'
The 2nd part?
uhuh ... thanks man! will try to do but imma be lazy :/
yea that one done ... but now plz do this oneSorry for the late reply! I believe you answered this?
No silly mistakes this time!
The Sarcastic Retardyea that one done ... but now plz do this one
Retard bruh ... I ain't got the energy to try that and electric fields together so.
let <ADE = aJust the last two , thanks a lot !
Great!
thanks a lot! and the last problem if it isn't too much trouble....
Thanks. ^_^
How to solve 9 b) ?
the common difference, r = 2cosθ / √3
