Lösung

\frac{\partial}{\partial x} (y^{2} sin (x y))

y^{3} cos (y x)

Schritte zur Lösung

\frac{\partial}{\partial x} (y^{2} sin (x y))

Behandle

y

als Konstante

Entferne die Konstante:

(a \cdot f)^{'} = a \cdot f^{'}

= y^{2} \frac{\partial}{\partial x} (sin (x y))

Wende die Kettenregel an:

cos (x y) \frac{\partial}{\partial x} (x y)

= cos (x y) \frac{\partial}{\partial x} (x y)

\frac{\partial}{\partial x} (x y) = y

= y^{2} cos (x y) y

Vereinfache

y^{2} cos (x y) y : y^{3} cos (y x)

= y^{3} cos (y x)
