(\partial)/(\partial x)((x/y)e^{xy})

Lösung

\frac{\partial}{\partial x} ((\frac{x}{y}) e^{x y})

\frac{e ^{x y} + e ^{x y} x y}{y}

Schritte zur Lösung

\frac{\partial}{\partial x} ((\frac{x}{y}) e^{x y})

Behandle

y

als Konstante

Entferne die Konstante:

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

= \frac{1}{y} \frac{\partial}{\partial x} (x e^{x y})

Wende die Produktregel an:

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

f = x, g = e^{x y}

= \frac{1}{y} (\frac{\partial}{\partial x} (x) e^{x y} + \frac{\partial}{\partial x} (e^{x y}) x)

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

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

= \frac{1}{y} (1 \cdot e^{x y} + e^{x y} y x)

Vereinfache

\frac{1}{y} (1 \cdot e^{x y} + e^{x y} y x) : \frac{e ^{x y} + e ^{x y} x y}{y}

= \frac{e ^{x y} + e ^{x y} x y}{y}
