derivative of (sec(x)/x)

Lösung

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

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

Schritte zur Lösung

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

Wende die Quotientenregel an:

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

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

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

\frac{d x}{d x} = 1

= \frac{sec ( x ) tan ( x ) x - 1 \cdot sec ( x )}{x ^{2}}

Vereinfache

\frac{sec ( x ) tan ( x ) x - 1 \cdot sec ( x )}{x ^{2}} : \frac{- 1 + x tan ( x )}{x ^{2} cos ( x )}

= \frac{- 1 + x tan ( x )}{x ^{2} cos ( x )}
