(\partial)/(\partial x)(x(sin(xy)))

Lösung

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

sin (x y) + x y cos (x y)

Schritte zur Lösung

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

Behandle

y

als Konstante

Wende die Produktregel an:

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

f = x, g = sin (x y)

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

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

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

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

Vereinfache

= sin (x y) + x y cos (x y)
