derivative of x^3-x-1

Lösung

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

Lösung

3 x^{2} - 1

Schritte zur Lösung

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

Wende die Summen-/Differenzregel an:

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

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

\frac{d}{d x} (x^{3}) = 3 x^{2}

\frac{d x}{d x} = 1

\frac{d}{d x} (1) = 0

= 3 x^{2} - 1 - 0

Vereinfache

= 3 x^{2} - 1
