Homework Statement I'm not sure how the graph looks like for the path |z-i| = pi Homework Equations I know that if the function is |z-i|=1 means a unit circle center at i The Attempt at a Solution Does that mean |z-i|=pi is a circle center at pi with a radius of pi? Thanks

Hi, I have some questions regarding how to find the analytisity region of a funtion. I'm a little confuse after I studied the definition of analytic function: which it saids [if a function f is differentiable at every z in A, then f is analytic on A] eg. Log z is analytic on the entire...
