derivative of |x-1|+|2x+3|

Lösung

\frac{d}{d x} (∣ x - 1 ∣ + ∣ 2 x + 3 ∣)

\frac{x - 1}{∣ x - 1 ∣} + \frac{2 ( 2 x + 3 )}{∣ 2 x + 3 ∣}

Schritte zur Lösung

\frac{d}{d x} (∣ x - 1 ∣ + ∣ 2 x + 3 ∣)

Wende die Summen-/Differenzregel an:

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

= \frac{d}{d x} (∣ x - 1 ∣) + \frac{d}{d x} (∣ 2 x + 3 ∣)

\frac{d}{d x} (∣ x - 1 ∣) = \frac{x - 1}{∣ x - 1 ∣}

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

= \frac{x - 1}{∣ x - 1 ∣} + \frac{2 ( 2 x + 3 )}{∣ 2 x + 3 ∣}
