To prove that if \( z, z' \) are complex numbers, then \( \arg(z) = -\arg(z') \), we can follow these steps: ### Step 1: Define the Complex Numbers Let \( z = x + iy \), where \( x \) and \( y \) are real numbers, and \( i \) is the imaginary unit. The complex conjugate of \( z \), denoted as \( z' \), is given by: \[ z' = x - iy \] ...
