ableitung von

f (x) = x^{3} - 3 x^{2} + 2

\frac{( x ^{3} - 3 x ^{2} + 2 ) ( 3 x ^{2} - 6 x )}{∣ x ^{3} - 3 x ^{2} + 2 ∣}

Schritte zur Lösung

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

Wende die Kettenregel an:

\frac{x ^{3} - 3 x ^{2} + 2}{∣ ( x ^{3} - 3 x ^{2} + 2 ) ∣} \frac{d}{d x} (x^{3} - 3 x^{2} + 2)

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

\frac{d}{d x} (x^{3} - 3 x^{2} + 2) = 3 x^{2} - 6 x

= \frac{x ^{3} - 3 x ^{2} + 2}{∣ ( x ^{3} - 3 x ^{2} + 2 ) ∣} (3 x^{2} - 6 x)
