derivative of

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

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

Solution steps

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

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

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

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

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

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

Simplify

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

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

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

y = (x + 1) (x + 2) (x - 3)

4 t^{2} - 15 t + 25

\frac{x ^{4}}{9}

(x^{2} + x)^{x}
