Find the non-zero complex numbers `z` satisfying ` barz =i z^2dot`

Text Solution

AI Generated Solution

To solve the equation \( \bar{z} = i z^2 \) for non-zero complex numbers \( z \), we will follow these steps: ### Step 1: Express \( z \) in terms of its real and imaginary parts Let \( z = x + iy \), where \( x \) and \( y \) are real numbers. The conjugate of \( z \) is given by: \[ \bar{z} = x - iy \] ...
