If z = x + iy lies in the third quadrant...

If z = x + iy lies in the third quadrant, then prove that `(barz)/(z)` also lies in the third quadrant when `y lt x lt 0`

Text Solution

AI Generated Solution

To prove that \(\frac{\bar{z}}{z}\) lies in the third quadrant when \(z = x + iy\) lies in the third quadrant and \(y < x < 0\), we will follow these steps: ### Step 1: Define the complex number and its conjugate Let \(z = x + iy\), where \(x < 0\) and \(y < 0\) (since \(z\) is in the third quadrant). The conjugate of \(z\) is given by: \[ \bar{z} = x - iy \] ...
