Lösung

\frac{\partial}{\partial t} (s^{2} + t^{2})

\frac{t}{s ^{2} + t ^{2}}

Behandle

s

als Konstante

Wende die Kettenregel an:

\frac{1}{2 s ^{2} + t ^{2}} \frac{\partial}{\partial t} (s^{2} + t^{2})

= \frac{1}{2 s ^{2} + t ^{2}} \frac{\partial}{\partial t} (s^{2} + t^{2})

\frac{\partial}{\partial t} (s^{2} + t^{2}) = 2 t

= \frac{1}{2 s ^{2} + t ^{2}} \cdot 2 t

Vereinfache

\frac{1}{2 s ^{2} + t ^{2}} \cdot 2 t : \frac{t}{s ^{2} + t ^{2}}

= \frac{t}{s ^{2} + t ^{2}}
