Talk:Calculus/Power series

Help!
This page badly needs attention. I've tidied up some of it, but it still lacks content. Carl Turner 21:28, 26 May 2007 (UTC)

Problems
This page falsely implied all series have finite radii of convergence. Corrected and expanded. Also, series aren't always expanded around x=0, notably ln x. More work is needed, maybe including quote of full Taylor-Mclaurin expansion. - Robert 2/4/4

convergence
after find the convergence radius need to test the extremities.

eg: if the radius is 5 and the center is -3 the extremities is -8 and +2, so you need to test if the series converge with -8 and +2.
