derivative of xsqrt(400-x^2)

Lösung

\frac{d}{d x} (x 400 - x^{2})

\frac{- 2 x ^{2} + 400}{400 - x ^{2}}

Schritte zur Lösung

\frac{d}{d x} (x 400 - x^{2})

Wende die Produktregel an:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x, g = 400 - x^{2}

= \frac{d x}{d x} 400 - x^{2} + \frac{d}{d x} (400 - x^{2}) x

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

\frac{d}{d x} (400 - x^{2}) = - \frac{x}{400 - x ^{2}}

= 1 \cdot 400 - x^{2} + (- \frac{x}{400 - x ^{2}}) x

Vereinfache

1 \cdot 400 - x^{2} + (- \frac{x}{400 - x ^{2}}) x : \frac{- 2 x ^{2} + 400}{400 - x ^{2}}

= \frac{- 2 x ^{2} + 400}{400 - x ^{2}}
