Rätsel in Failed to parse (Conversion error. Server ("https://wikimedia.org/api/rest_") reported: "Cannot get mml. Server problem."): {\displaystyle \mathbb {C} }

Was liefern die folgenden Funktionen zurück?

$f_{1}(z)={\frac {\left|z\right|^{2}}{z}}$

$f_{2}(z)={\frac {i\left|z\right|^{2}}{z}}$

$f_{3}(z)={\frac {z^{2}+\left|z\right|^{2}}{2z}}$

$f_{4}(z)={\frac {z^{2}-\left|z\right|^{2}}{2z}}$
