derivative of 4/x-1/(x^3)

Lösung

\frac{d}{d x} (\frac{4}{x} - \frac{1}{x ^{3}})

Lösung

- \frac{4}{x ^{2}} + \frac{3}{x ^{4}}

Schritte zur Lösung

\frac{d}{d x} (\frac{4}{x} - \frac{1}{x ^{3}})

Wende die Summen-/Differenzregel an:

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

= \frac{d}{d x} (\frac{4}{x}) - \frac{d}{d x} (\frac{1}{x ^{3}})

\frac{d}{d x} (\frac{4}{x}) = - \frac{4}{x ^{2}}

\frac{d}{d x} (\frac{1}{x ^{3}}) = - \frac{3}{x ^{4}}

= - \frac{4}{x ^{2}} - (- \frac{3}{x ^{4}})

Vereinfache

= - \frac{4}{x ^{2}} + \frac{3}{x ^{4}}
