Homework Help: Taylor Series Expansion About the Point i

  1. Jun 23, 2010 #1
    Taylor Series Expansion About the Point "i"

    1. The problem statement, all variables and given/known data

    Calculate the radius of convergence of the Taylor series for

    [tex]\frac{1}{z^2-2z+2}[/tex]

    about the point i.

    3. The attempt at a solution

    I can find the radius of convergence if I can determine the expansion but I can't seem to spot the pattern...

    Any help will be appreciated (please see attached).
