Oh thank you very much I have learned something very important. So now I just need to plot xy plane with i along the y-axis and numbers (radius) along the x axis. The circle with initiate from point -i with radius of 2. So how will i know that the radius is 2 along the y-axis since its a...

cross multiplication makes it |(z+i)^2|<4 then square root of 4 =2 so |(z-(-i)|< 2

Since its convergence r is equals to 1. Unless i have to multiply by the denominator of 4?

No I don't know that. So in this case c=-i?

To be honest I don't have a clue now as in most cases we have only worked out if the series in convergence or divergent. This is new to me. Are they any textbooks or websites u recommend for learning this stuff? Anyway thanks for your help guys

Thats the problem mate. I just don't have a clue on what to do after this stage. I have look a various textbooks and online without success.

Homework Statement I am struggling to answer this question please help Find the region of convergence for the following complex series and draw the region Ʃ(i+z)^(2n-1)/2^(2n+1)The Attempt at a Solution Here is my hand written working, sorry i could figure out how to use the symbols...
