derivative f(x)=4(x^2+4x)^3

Lösung

ableitung von

f (x) = 4 (x^{2} + 4 x)^{3}

12 (x^{2} + 4 x)^{2} (2 x + 4)

Schritte zur Lösung

\frac{d}{d x} (4 (x^{2} + 4 x)^{3})

Entferne die Konstante:

(a \cdot f)^{'} = a \cdot f^{'}

= 4 \frac{d}{d x} ((x^{2} + 4 x)^{3})

Wende die Kettenregel an:

3 (x^{2} + 4 x)^{2} \frac{d}{d x} (x^{2} + 4 x)

= 3 (x^{2} + 4 x)^{2} \frac{d}{d x} (x^{2} + 4 x)

\frac{d}{d x} (x^{2} + 4 x) = 2 x + 4

= 4 \cdot 3 (x^{2} + 4 x)^{2} (2 x + 4)

Vereinfache

= 12 (x^{2} + 4 x)^{2} (2 x + 4)

y^{^{'}} = - y^{3}

\frac{d}{d x} (5 + tan^{2} (x))

\frac{\partial}{\partial y} (y^{6} sin (4 x))

\int_{0}^{1} 1 + x d x

\int_{0}^{1} π (1 - x^{2})^{2} d x
