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

expand

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

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

Solution steps

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

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

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

3 (ln (2 x + 5) + \frac{2 x}{2 x + 5}) (2 x + 5)^{3 x}

d x (sec (2 x) + tan (3 x))

lo g_{5 (3 x - 1)} (2)

cot (\frac{1}{2} (x + y)) cot (\frac{1}{2} (x - y))

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