The amplitude of a complex number

Postby TheTruth1 » Sun May 28, 2017 2:44 am

Why the amplitude [theta] is to be determined from the two relations x=r cos[theta] and y=r sin[theta] simultaneously and not from the single relation [theta]=tan^-1 (y/x) only???

Is this related to a science project? If so, tell us more about your experiment.

This forum is for helping students with their science fair project. If your question is not related to a science fair project, there are other online forums that are more suited to help you.

Thank you.
