derivative t^2e^t

解

導関数

t^{2} e^{t}

解

2 t e^{t} + e^{t} t^{2}

解答ステップ

\frac{d}{d t} (t^{2} e^{t})

積の法則を適用:

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

f = t^{2}, g = e^{t}

= \frac{d}{d t} (t^{2}) e^{t} + \frac{d}{d t} (e^{t}) t^{2}

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

\frac{d}{d t} (e^{t}) = e^{t}

= 2 t e^{t} + e^{t} t^{2}
