Well
I am sort of like stuck. But I have to face these. TO be honest arildno I don't know that also. :cry:
What am I to do? have any website that I can learn all these and come back to you?
I am just in the A/L class. Just finished my Local O/Ls. I just swiched to the english medium now. I don't know, realy that teacher is too advance sort of. Even the other students also sort of get fedup of maths like. But I am trying to somehow keep up. He told us that there is a big gap between...
Oh I see. So this \lim_{N\to\infty}S_{N}=S is something about a limit. Realy great to learn about this. I didn't know about this. Actualy I haven't done this yet. Ok I get it now.
ok arildno I get it upto here without any problem. Now my next step will be?
Ok I got it now
Hi VietDao29 thanks for your post about the meaning of the Capital letter of zigma with the other letters. Realy useful. Thanks alot.
Ya now I undertand. Okay we have now got a meaningful concept for Sn. Earlier I had a little problem in undertanding the symbol, but now I get...
Ya right. 1 is the bound because if it gose beyond 1 then we wont find a bound because we can get large numbers right?
Anyway this is the first time I used this symbol next to the "Sn ="
Can you teach me about this also?
S=\sum_{n=0}^{\infty}x^{n}
uhh arildno does converge means like bringing it to one place like? Sorry to ask this because I am from a non-english country?
Ya I agree that now the S has a meaningful value.
Now, consider the situation when x<-1:
What happens if N is a really big EVEN number?
The value for X will be positive right?
and the answer will be negative. I mean Sn
What happens if N is a really big ODD number?
The value for X will be negative right?
and the answer will be positive. I mean Sn
