derivative of sqrt(x^2+1)+2xe^x

解

\frac{d}{d x} (x^{2} + 1 + 2 x e^{x})

解

\frac{x}{x ^{2} + 1} + 2 (e^{x} + e^{x} x)

解答ステップ

\frac{d}{d x} (x^{2} + 1 + 2 x e^{x})

和/差の法則を適用:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d}{d x} (x^{2} + 1) + \frac{d}{d x} (2 x e^{x})

\frac{d}{d x} (x^{2} + 1) = \frac{x}{x ^{2} + 1}

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

= \frac{x}{x ^{2} + 1} + 2 (e^{x} + e^{x} x)
