derivative of arccos(e^{-x})

Solution

\frac{d}{d x} (arccos (e^{- x}))

Solution

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

Solution steps

\frac{d}{d x} (arccos (e^{- x}))

Apply the chain rule:

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

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

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

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

Simplify

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

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