(\partial)/(\partial x)((x-1)y^2e^{xy})

Lösung

\frac{\partial}{\partial x} ((x - 1) y^{2} e^{x y})

y^{2} (e^{x y} + e^{x y} y (x - 1))

Schritte zur Lösung

\frac{\partial}{\partial x} ((x - 1) y^{2} e^{x y})

Behandle

y

als Konstante

Entferne die Konstante:

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

= y^{2} \frac{\partial}{\partial x} ((x - 1) e^{x y})

Wende die Produktregel an:

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

f = x - 1, g = e^{x y}

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

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

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

= y^{2} (1 \cdot e^{x y} + e^{x y} y (x - 1))

Vereinfache

= y^{2} (e^{x y} + e^{x y} y (x - 1))

\frac{d y}{d x} = \frac{y}{2 x}
