derivative of sqrt(x)e^{xy}

Lösung

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

\frac{e ^{x y}}{2 x} + e^{x y} x (y + x \frac{d y}{d x})

Schritte zur Lösung

\frac{d}{d 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{d}{d x} (x) e^{x y} + \frac{d}{d x} (e^{x y}) x

\frac{d}{d x} (x) = \frac{1}{2 x}

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

= \frac{1}{2 x} e^{x y} + e^{x y} (y + x \frac{d y}{d x}) x

\frac{1}{2 x} e^{x y} = \frac{e ^{x y}}{2 x}

= \frac{e ^{x y}}{2 x} + e^{x y} x (y + x \frac{d y}{d x})

\frac{\partial}{\partial x} (4 e^{x} - 2 x e^{y})
