Does there exist a power series expansion of log z around z=0? If so, what is it? If not, demonstrate that it is impossible.
Here is the expansion of log z around z=1.
The Attempt at a Solution
I'm actually trying to find the value of the singularity at z=0 (the coefficient of 1/(z-a) around z=a), if it's possible. I have no idea what to do.
