(\partial)/(\partial y)(x*ln(x+2y)+x/y)

Lösung

\frac{\partial}{\partial y} (x \cdot ln (x + 2 y) + \frac{x}{y})

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

Schritte zur Lösung

\frac{\partial}{\partial y} (x ln (x + 2 y) + \frac{x}{y})

Wende die Summen-/Differenzregel an:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{\partial}{\partial y} (x ln (x + 2 y)) + \frac{\partial}{\partial y} (\frac{x}{y})

\frac{\partial}{\partial y} (x ln (x + 2 y)) = \frac{2 x}{x + 2 y}

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

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