Complex Analysis - Sketching regions in a complex plane

Click For Summary
SUMMARY

The discussion centers on the inequality |2z - 1| ≥ |z + i| in the context of complex analysis. Participants explore methods to approach the problem, particularly focusing on the transformation of the expression to 2|z - 1/2| ≥ |z + i|. This transformation is crucial for sketching the regions in the complex plane defined by the inequality. The conversation highlights the importance of understanding geometric interpretations in complex analysis.

PREREQUISITES

Homework Statement


|2z -1|[itex]\geq[/itex]|z + i|


The Attempt at a Solution


The problem I have with this one is the 2z, I just need a clue on how to go about centering this one. If it were just |z - 1|; z[itex]_{0}[/itex] would be 1.

Hi NewtonianAlch! :smile:

2|z - 1/2| ≥ |z + i| :wink:
 
Oh dear...I think I need a long break...thanks for the reply!
