Hello there, I was having some trouble with this problem:

Find the Taylor series for f centered at 4 if:

What is the radius of convergence of the Taylor series?

Help appreciates.

The problem is ill defined, we have no sufficient information about . For example

We have . However: a) The Taylor series of centered at has radius of convergence . b) The Taylor series of centered at does not exist . - November 19th 2011, 01:07 AMchisigmaRe: Finding Taylor series for f
May be that a further explanation from me is necessary... if we consider the series expansion...

(1)

...it is not too difficult to obtain...

(2)

Now the f(*) defined in (2) is analytic for and that means that its series expansion centered in has radius of convergence ...

Kind regards
