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

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

Solution steps

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

Apply the chain rule:

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

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

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

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

Simplify

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

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