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

Lösung

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

\frac{2}{x ^{3}}

Schritte zur Lösung

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

Behandle

y

als Konstante

Wende die Summen-/Differenzregel an:

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

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

\frac{\partial}{\partial x} (\frac{1}{x ^{2}}) = - \frac{2}{x ^{3}}

\frac{\partial}{\partial x} (e^{- y}) = 0

= - (- \frac{2}{x ^{3}}) + 0

Vereinfache

= \frac{2}{x ^{3}}

\frac{d y}{d x} = y (1 + x)^{- 1}

\int \frac{1}{( x + 3 ) ( x + 5 )} d x

\frac{\partial}{\partial x} ((5 x - x^{2}) cos (t))
