Lösung

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

- \frac{e ^{\frac{y}{x}} y ^{2}}{x ^{2}}

Schritte zur Lösung

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

Behandle

y

als Konstante

Entferne die Konstante:

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

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

Wende die Kettenregel an:

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

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

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

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

Vereinfache

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

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

x \to 1 lim (\frac{e ^{x - 1} - 1}{ln ^{2} ( x )})

a re a x^{2} - 4 x + 3, 3 + 4 x - x^{2}

\int_{- 1}^{1} (x^{2} - 1) d x
