1. ### I can't understand this in partial fractions

hi arildno, Uhh were you able to get anything? Well it's ok take your time, I am not in a hurry.
2. ### I can't understand this in partial fractions

Ok no problem. Realy appreciate your intrest in helping me. Can't believe, but realy you are great person. Thanks alot Hope I will find a solution.
3. ### I can't understand this in partial fractions

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?
4. ### I can't understand this in partial fractions

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...
5. ### I can't understand this in partial fractions

I am sort of Sorry arildno :frown: I havn't learnt any of them. Will it be very difficult for me to learn it?:smile:
6. ### I can't understand this in partial fractions

you mean like |x|<1 right?
7. ### I can't understand this in partial fractions

Is this like the pascal trangle. I mean some what related to the binomial theorem?
8. ### I can't understand this in partial fractions

oh ya I see. Yep agreed.

Yep agreed
10. ### I can't understand this in partial fractions

Ya no problem at all.
11. ### I can't understand this in partial fractions

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?
12. ### I can't understand this in partial fractions

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...
13. ### I can't understand this in partial fractions

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}
14. ### I can't understand this in partial fractions

Oh please continue please? I can realy understand what you teach me than my school teacher.
15. ### I can't understand this in partial fractions

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.
16. ### I can't understand this in partial fractions

Will Sn approximately be equal to = 1/1-x Am I right?
17. ### I can't understand this in partial fractions

Right right it will be very close to zero. I mean it will go on like 0.0000000000001323 like that right?
18. ### I can't understand this in partial fractions

I mean when you multiply it by itself.
19. ### I can't understand this in partial fractions

Well it say the number = y and |y|<1 then the product will be less than the number right?
20. ### I can't understand this in partial fractions

I think I am a little confused. Does this happen because |x| < 1 will at a certain stage reach 0 I mean like x = 0
21. ### I can't understand this in partial fractions

So because of the absolute value are we getting positive values for X?
22. ### I can't understand this in partial fractions

Either positive or negative values right?
23. ### I can't understand this in partial fractions

The value gets smaller and smaller right?
24. ### I can't understand this in partial fractions

What does |x|<1 this mean? i mean by using |x|

ya agreed.
26. ### I can't understand this in partial fractions

Ya agreed. Because the n is changing right? from odd to even and even to odd like that it will go on right?
27. ### I can't understand this in partial fractions

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
28. ### I can't understand this in partial fractions

Oh my you will get a very big answer. Right?
29. ### I can't understand this in partial fractions

Oh ya ya. i see. That's very clear. Thanks for expressing it like that. ok agreed.
30. ### I can't understand this in partial fractions

hi arildno, We put the (1-x) Sn = 1-x^n the 1 in front of -x (the one in front of Sn) come because all get canceled right?
