$\lim_{z\to 0}\frac{\bar z} z$

I think that the limit is 1 but i'm not sure how to show that

    Do you mean $\lim_{z \to 0}\frac{z^*}{z}$? And if so, what does $z^*$ mean?2012-11-03

    Do you mean $\lim\limits_{z\to 0} \frac{\overline{z}} z ?$ If so, try writing $z$ in exponential form.2012-11-03
