Material Needed for Power Series

[bobber205]

I'm in a "series and sequences" class. Up until power series, if I studied the material a decent amount and did a lot of practice problems, things made sense.

We got to power series today and I simply am not getting anything. I read the chapter in the book just now and it totally lost me.


It doesn't seem like a vastly more complicated affair than regular series. Am I right?
Are there any good resources on the net for this you guys could recommend?

Thanks!

it's more complicated than a series of constants because there's a variable involved, and convergence of the series depends on values of that variable. if you understand regular series, i guess power series is that next step though

Are there any good online resources? :)
