Main Question or Discussion Point

Hi I'm wondering if the z- (complex conjugate of z) goes to zero as z does? Also what is the derivative of z- with respect to z? Thanks

The map f(z)= conjugate of z is not differentiable, and you should be able to prove this from the definition.

Do you know how to calculate complex limits by breaking them up into their real and imaginary parts? It makes looking at that limit very easy

While we're on the subject of complex limits, can anyone help me figure out what
[tex]
\lim_{z\to 0} \text{Log } z
[/tex]
is? (So we're talking about the principal logarithm here.)
