So I'm working on the proof of the generalized uncertainty principle and there is a step that I'm not fully understanding. There is a line were it says that for any complex number we can write the inequality as [Re(z)]^2 + [Im(z)]^2 >/ [Im(z)]^2. why are we able to get rid of the real part on the left hand side?(adsbygoogle = window.adsbygoogle || []).push({});

Does this have anything to do with the magnitude being greater than the magnitude of the imaginary part?
