Homework Help: Where are these functions analytic?

  1. Jan 22, 2009 #1
    Greetings all, I have 2 functions:

    [tex]\frac{1}{Rez} + \frac{1}{Imz}(z^{2}- \overline{z}^{2})[/tex]

    and

    [tex]\frac{1}{Rez} + \frac{1}{i Imz}(z^{2}- \overline{z}^{2})[/tex]

    I have to find where they are analytic, how do I start this?

    A good place to start is to look up the definition of analytic :smile:

    You may also want to look up "Cauchy-Riemann equations". They provide a simple test for the analyticity of a function.
