sin (5 x^{2} y) + 10 x^{2} y cos (5 x^{2} y)

Schritte zur Lösung

\frac{\partial}{\partial x} (x sin (5 x^{2} y))

Behandle

y

als Konstante

Wende die Produktregel an:

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

f = x, g = sin (5 x^{2} y)

= \frac{\partial}{\partial x} (x) sin (5 x^{2} y) + \frac{\partial}{\partial x} (sin (5 x^{2} y)) x

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

\frac{\partial}{\partial x} (sin (5 x^{2} y)) = cos (5 x^{2} y) \cdot 10 y x

= 1 \cdot sin (5 x^{2} y) + cos (5 x^{2} y) \cdot 10 y xx

Vereinfache

1 \cdot sin (5 x^{2} y) + cos (5 x^{2} y) \cdot 10 y xx : sin (5 x^{2} y) + 10 x^{2} y cos (5 x^{2} y)

= sin (5 x^{2} y) + 10 x^{2} y cos (5 x^{2} y)
