(\partial)/(\partial y)(-sin(xy)y)

Lösung

\frac{\partial}{\partial y} (- sin (x y) y)

- x y cos (x y) - sin (x y)

Schritte zur Lösung

\frac{\partial}{\partial y} (- sin (x y) y)

Behandle

x

als Konstante

Entferne die Konstante:

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

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

Wende die Produktregel an:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = sin (x y), g = y

= - (\frac{\partial}{\partial y} (sin (x y)) y + \frac{\partial}{\partial y} (y) sin (x y))

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

\frac{\partial}{\partial y} (y) = 1

= - (cos (x y) x y + 1 \cdot sin (x y))

Vereinfache

= - x y cos (x y) - sin (x y)
