Is that 1/(z+1) or 1/z + 1
Hi all
I'm trying to get my head around the Laurent series for the following function :
f(z) = zsinh(1/z+1)
about -1 and trying to give the general term of the series for odd and even powers of (z+1).
Also, how would I write down a punctured open disk D, containing the circle C={z:|z+1|=1} of which f is represented on this series, and what would be the nature of teh singularity of f at -1.
Any help would be greatly appreciated.
Many thanks
