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

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

Solution steps

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

Apply exponent rule:

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

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

Apply the chain rule:

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

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

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

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

Simplify

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

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

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

\int sin (- 5 x) d x

\int (e^{5 x}) d x

\int x + 3 - 3 d x
