Hi i found this "error" in my textbook in series.

https://www.physicsforums.com/attachment.php?attachmentid=9420&stc=1&d=1173538014

This is a geometric one, it converges for |z|< 1/rot(2) when i calculate this, but the textbook claims that |z|<1/2

I also checked different values on z and i get a finite value even when z is 0,7

[ 0,5< 0,7 < 1/rot(2) ]

Who is right?
