Hi all I have the following problem:
Sketch the following region in the complex plane:
|z+1+i| greater than or equal to 1
i worked through the problem and got the solution (x+1)^2 + (y+1)^2 greater than or equal to 1^2
My question is: how is a circle of radius 1 possibly going to be greater than its own radius? if i'm completely wrong, what does the 1^2 represent other than the radius of the circle?
