d/(dz)((z^2)/((z-2i)^2))

Lösung

\frac{d}{d z} (\frac{z ^{2}}{( z - 2 i ) ^{2}})

- \frac{4 i z}{( z - 2 i ) ^{3}}

Schritte zur Lösung

\frac{d}{d z} (\frac{z ^{2}}{( z - 2 i ) ^{2}})

Wende die Quotientenregel an:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= \frac{\frac{d}{d z} ( z ^{2} ) ( z - 2 i ) ^{2} - \frac{d}{d z} ( ( z - 2 i ) ^{2} ) z ^{2}}{( ( z - 2 i ) ^{2} ) ^{2}}

\frac{d}{d z} (z^{2}) = 2 z

\frac{d}{d z} ((z - 2 i)^{2}) = 2 z - 4 i

= \frac{2 z ( z - 2 i ) ^{2} - ( 2 z - 4 i ) z ^{2}}{( ( z - 2 i ) ^{2} ) ^{2}}

Vereinfache

\frac{2 z ( z - 2 i ) ^{2} - ( 2 z - 4 i ) z ^{2}}{( ( z - 2 i ) ^{2} ) ^{2}} : - \frac{4 i z}{( z - 2 i ) ^{3}}

= - \frac{4 i z}{( z - 2 i ) ^{3}}
