If the argument of the complex number is -π/2 then the complex number lies on the negative Im(z) (the Re(z)=0 line) axis and so the real part will be 0.what I'm saying is that inside the argument there should be no real terms, only imaginary terms which will be negative.

Thank you for spotting that. I was supposed to do Re(z) = 0 line.
