Thanks for welcoming :) I thought the question was, if it helpful and if the computation of derivative when x > 1 tells us something. if x < 1 then we can compute useful things, but is the complex derivative of the function helpful?

I don't know if I'm right... But as I see it, circle is not defined for any x > 1 since radius of this circle is 1. At a point x > 1 there is no circle so I don't think it's of any use..
