Complex analysis

  1. Feb 12, 2007 #1
    Can anyone give me some advice on how to solve this problem?

    in the reflection principle if f(x) is pure imaginary then the conjugate of f(z)=-f(z*) where z* is the complex conjugate of z.

    Any advice on where to start?

    hint: if f is purely imaginary, then one can write f(z)=iy, for some real number, y.
