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

Lösung

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

Lösung

A (2 e^{- 2 x} x - 2 e^{- 2 x} x^{2})

Schritte zur Lösung

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

Entferne die Konstante:

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

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

Wende die Produktregel an:

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

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

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

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

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

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

Vereinfache

= A (2 e^{- 2 x} x - 2 e^{- 2 x} x^{2})
