derivative f(x)=sqrt(x^2+21)

Lösung

ableitung von

f (x) = x^{2} + 21

Lösung

\frac{x}{x ^{2} + 21}

Schritte zur Lösung

\frac{d}{d x} (x^{2} + 21)

Wende die Kettenregel an:

\frac{1}{2 x ^{2} + 21} \frac{d}{d x} (x^{2} + 21)

= \frac{1}{2 x ^{2} + 21} \frac{d}{d x} (x^{2} + 21)

\frac{d}{d x} (x^{2} + 21) = 2 x

= \frac{1}{2 x ^{2} + 21} \cdot 2 x

Vereinfache

\frac{1}{2 x ^{2} + 21} \cdot 2 x : \frac{x}{x ^{2} + 21}

= \frac{x}{x ^{2} + 21}
