Question
Determine the set of all \( z \) for which \( f(z) = \frac{1}{1 - i\bar{z}} \) is defined, and then write \( f(z) \) in \( u(x, y) + iv(x, y) \) form.

Here, \( \bar{z} \) denotes the complex conjugate of \( z \).

Note: The image features a highlighted fraction \( \frac{1}{1 - i\bar{z}} \) with an arrow pointing to it for emphasis.

Expert Solution
Step 1: Given:

 f open parentheses z close parentheses equals fraction numerator 1 over denominator 1 minus i space z with bar on top end fraction

We have to write f open parentheses z close parentheses in u open parentheses x comma y close parentheses plus i space v open parentheses x comma y close parentheses form.
