(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The limit of ln([tex]\frac{1-\frac{ix}{z}}{1+\frac{ix}{z}}[/tex]) as x goes to 0

3. The attempt at a solution

I am using taylor where f = [tex]\frac{1-\frac{ix}{z}}{1+\frac{ix}{z}}[/tex]

f'(0) -[tex]\frac{2i}{z}[/tex]

Is this correct? Can you take the derivative just as equations without imaginary numbers?
