derivative of x^2e^{-0.04x}

Lösung

\frac{d}{d x} (x^{2} e^{- 0.04 x})

Lösung

2 e^{- 0.04 x} x - 0.04 e^{- 0.04 x} x^{2}

Schritte zur Lösung

\frac{d}{d x} (x^{2} e^{- 0.04 x})

Wende die Produktregel an:

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

f = x^{2}, g = e^{- 0.04 x}

= \frac{d}{d x} (x^{2}) e^{- 0.04 x} + \frac{d}{d x} (e^{- 0.04 x}) x^{2}

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

\frac{d}{d x} (e^{- 0.04 x}) = - 0.04 e^{- 0.04 x}

= 2 x e^{- 0.04 x} + (- 0.04 e^{- 0.04 x}) x^{2}

Vereinfache

= 2 e^{- 0.04 x} x - 0.04 e^{- 0.04 x} x^{2}
