I have a complex voltage = 10-j20. I am trying to convert it to polar coordinates with my Ti 89 but I keep getting my answers in arc tan. Can someone show me a way to restrict this answer within -pi and pi so I don't get any arc tan in my conversion.
As I have shown before, the conversion with the final answer of V in Polar coordinates as:
V = ...
This solution provides calculations for converting polar coordinates.
