(\partial)/(\partial z)(xze^{yz})

Lösung

\frac{\partial}{\partial z} (x z e^{yz})

x (e^{zy} + e^{zy} zy)

Schritte zur Lösung

\frac{\partial}{\partial z} (x z e^{yz})

Behandle

x, y

als Konstanten

Entferne die Konstante:

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

= x \frac{\partial}{\partial z} (z e^{yz})

Wende die Produktregel an:

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

f = z, g = e^{yz}

= x (\frac{\partial}{\partial z} (z) e^{yz} + \frac{\partial}{\partial z} (e^{yz}) z)

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

\frac{\partial}{\partial z} (e^{yz}) = e^{yz} y

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

Vereinfache

= x (e^{zy} + e^{zy} zy)

y^{^{'}} = 0.23 y - 0.0005 y^{2}

\int_{0}^{60} (60 - y)^{2} d y

x y^{^{'}} + y = 3 x y

\int_{1}^{10} \frac{1}{x ^{2}} d x
