expand x/((1+e^{-x))^2}

expand

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

\frac{x}{1 + 2 e ^{- x} + e ^{- 2 x}}

Solution steps

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

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

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

\frac{9 π ( - 2 ln ( 3 ) - 1 )}{40}

x ((x - 4) (x - 3)) ((x - 2) (x - 1))

- \frac{( - x + 15 ) ( - x + 5 )}{2}

2 e^{y} (x + 4) y^{3}

cos ((n + 1) α)
