    See I like sigma! there's a reason I have a laptop for the rest of my exams apart from maths
    It make me feel more sophisticated

    I can't write lowercase sigma as it ends up looking like a 6 o.O
    I see. Do you...

    Start from point A or point B when writing it?

    I find it's easier to do it well if you start from point A.

    Well my 6th form is apparently in the second most deprived part of my area so I'm always bumping into people that talk like this and apparently at work I'm patronising people as I speak proper English and they just aren't familiar with it. Yeah that's exactly the same with me although I always ask for the challenge on TSR as I know that they can deliver
    Ahh loool, my secondary school was 'ghetto' but college is normal
    Haha I see, yeah when I stand in the shop I have to change the way I speak to different types of people, its like a guessing game, hopefully you get it right or may end up annoying a few people...were going off topic now

    I like the maths notations, they look cool! yeah I have difficulty with some of them though :s

    I sometimes write uppercase sigma using a ruler so that it comes out neatly :teehee:
    wha, upper case sigma is like the easiest thing

    Plenty of those in FP1

    my b's look more like 6's, so I hate when the two merge in one question I could mistakenly say b+6=r -> 2(6)=r herp derp, haven't done this in an exam yet thankfully
    Same. So while for factor theorem Qs generally people use b for x^2 + bx +3 for example for factorizing by inspection, i use p to reduce ambiguity.

    Point B, I'll try starting from point A!

    Yeah exactly the same, though for quartics in FP1 I usually rarely if never meet a 6) so I usually set up my equation like this
    (az^2+bz+c)(z^2+2z+5) and then equate coefficients, cubics are very boring (awaits someone undermining my quartic statement with things raised to the power of 15 or so )

    Or it can be other things, usually p, q and n (bound to cause some confusion) are my next 3 choices

    What? No they're pretty much all universally accepted/used symbols

    Oh okay take your time:yy: Sorry, if I'm asking too much
    Hmm, there might be a proof that it converges using A-level knowledge, but I'm not seeing it, and I haven't done nearly enough analysis to have any additional knowledge about limits, so you may be asking too much of me.

    couldn't you just say r<|1| lol that surely would mean it converges nvm

    It's not a geometric series because you have a new radical with every term.

    Is this actually possible for me to do without additional knowledge?
