derivative of sqrt(x^2+15)

Lösung

\frac{d}{d x} (x^{2} + 15)

Lösung

\frac{x}{x ^{2} + 15}

Schritte zur Lösung

\frac{d}{d x} (x^{2} + 15)

Wende die Kettenregel an:

\frac{1}{2 x ^{2} + 15} \frac{d}{d x} (x^{2} + 15)

= \frac{1}{2 x ^{2} + 15} \frac{d}{d x} (x^{2} + 15)

\frac{d}{d x} (x^{2} + 15) = 2 x

= \frac{1}{2 x ^{2} + 15} \cdot 2 x

Vereinfache

\frac{1}{2 x ^{2} + 15} \cdot 2 x : \frac{x}{x ^{2} + 15}

= \frac{x}{x ^{2} + 15}
