\frac{d}{d x} (\frac{sec ( x )}{8 + sec ( x )})

\frac{8 sec ( x ) tan ( x )}{( 8 + sec ( x ) ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{sec ( x )}{8 + sec ( x )})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( sec ( x ) ) ( 8 + sec ( x ) ) - \frac{d}{d x} ( 8 + sec ( x ) ) sec ( x )}{( 8 + sec ( x ) ) ^{2}}

\frac{d}{d x} (sec (x)) = sec (x) tan (x)

\frac{d}{d x} (8 + sec (x)) = sec (x) tan (x)

= \frac{sec ( x ) tan ( x ) ( 8 + sec ( x ) ) - sec ( x ) tan ( x ) sec ( x )}{( 8 + sec ( x ) ) ^{2}}

Simplify

\frac{sec ( x ) tan ( x ) ( 8 + sec ( x ) ) - sec ( x ) tan ( x ) sec ( x )}{( 8 + sec ( x ) ) ^{2}} : \frac{8 sec ( x ) tan ( x )}{( 8 + sec ( x ) ) ^{2}}

= \frac{8 sec ( x ) tan ( x )}{( 8 + sec ( x ) ) ^{2}}
