(\partial)/(\partial y)(x+x/(x^2+y^2))

Lösung

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

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

Schritte zur Lösung

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

Behandle

x

als Konstante

Wende die Summen-/Differenzregel an:

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

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

\frac{\partial}{\partial y} (x) = 0

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

= 0 - \frac{2 x y}{( x ^{2} + y ^{2} ) ^{2}}

Vereinfache

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

\frac{d y}{d x} = 4 e^{- 3 x}

\int e^{x} \cdot sin (e^{x}) d x
