derivative of

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

- \frac{3 x ^{2} + e ^{x} x + e ^{x}}{x ^{2} ( x ^{2} + e ^{x} ) ^{2}}

Solution steps

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

Apply exponent rule:

\frac{1}{a} = a^{- 1}

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

Apply the chain rule:

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

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

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

= - \frac{1}{( x ( x ^{2} + e ^{x} ) ) ^{2}} (3 x^{2} + e^{x} x + e^{x})

Simplify

- \frac{1}{( x ( x ^{2} + e ^{x} ) ) ^{2}} (3 x^{2} + e^{x} x + e^{x}) : - \frac{3 x ^{2} + e ^{x} x + e ^{x}}{x ^{2} ( x ^{2} + e ^{x} ) ^{2}}

= - \frac{3 x ^{2} + e ^{x} x + e ^{x}}{x ^{2} ( x ^{2} + e ^{x} ) ^{2}}

cos (\frac{x}{x + 1})

1 + 2 x y

2 x + cot (x)

sin^{2} (x) + tan^{3} (x)

\frac{d}{d t} \frac{500}{( t + 2 )} - \frac{1000}{( ( t + 2 ) ^{2} )}
