In Infinite series the sum of infinite series is the (partial sum).
Is that because its infinite and we can't sum up an infinite series ??

Best ResponseYou've already chosen the best response.0Well, it's convenient for looking at convergence and limits, no?

Best ResponseYou've already chosen the best response.0so what do you think of my question?.

Best ResponseYou've already chosen the best response.0Well, we can sum up the series (if the limit of partial sums exists)

Best ResponseYou've already chosen the best response.0we can? how do we know if the limit of partial sums exists?

Best ResponseYou've already chosen the best response.0so your saying if a series Converges it partial sums exists

Best ResponseYou've already chosen the best response.0Well, if a series diverges, there wouldn't be any convergence, right?

Best ResponseYou've already chosen the best response.0And you wouldn't be able to add it up however hard you tried

Best ResponseYou've already chosen the best response.0yes BUT because its a infinite series whether it converges or diverges we cant sum it all up?

Best ResponseYou've already chosen the best response.0That's what I'm saying, if it converges then you can (usually) add it up (analytically).

Best ResponseYou've already chosen the best response.0i see what your saying sure. i just don't see the idea of converges or diverges has anything to do with the fact that a series Converges and there for the partial sums exists

Best ResponseYou've already chosen the best response.0If the series converges then you can take a limit

anonymous

Best ResponseYou've already chosen the best response.0All well and good that you are saying the facts. :) i really want to understand why we can take a limit when series converges and not diverges.

Best ResponseYou've already chosen the best response.0the limit of a divergent series is infinite and some other limits might not exist (there are shades of convergence, absolute, conditional...)

anonymous

Best ResponseYou've already chosen the best response.0You must have a way, analyytically, to approach a limit (even if you do not actually ever reach it)

Best ResponseYou've already chosen the best response.0I am assuming you have studied calculus, the limit concept there is similar.

Best ResponseYou've already chosen the best response.0i see . if we say that x> 2 x approaches 2 . what comment would you have?

Best ResponseYou've already chosen the best response.0i have studied CAL but in a very mechanical way!

Best ResponseYou've already chosen the best response.0You can say it and it implies that the limit is 2 but doesn't say anything about how you got that.

Best ResponseYou've already chosen the best response.0do we care how we get there . is that important for us?

Best ResponseYou've already chosen the best response.0How do we know that your limit is valid?

Best ResponseYou've already chosen the best response.0The limit of 1 + 1/2 +1/4 + 1/8 ......+1/2^n has a limit of 2 Do you believe me?

Best ResponseYou've already chosen the best response.0well you told me thats

anonymous

Best ResponseYou've already chosen the best response.0Ok, it's not 2 it's 3

anonymous

Best ResponseYou've already chosen the best response.0Anyway, the point is that it converges and it is fairly easy to establish that 2 is an upper bound and with a little more work that the sum is actually 2
