derivative of (tan(x)/(cos(x)-4))

Lösung

\frac{d}{d x} (\frac{tan ( x )}{cos ( x ) - 4})

\frac{sec ^{2} ( x ) ( cos ( x ) - 4 ) + sin ( x ) tan ( x )}{( cos ( x ) - 4 ) ^{2}}

Schritte zur Lösung

\frac{d}{d x} (\frac{tan ( x )}{cos ( x ) - 4})

Wende die Quotientenregel an:

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

= \frac{\frac{d}{d x} ( tan ( x ) ) ( cos ( x ) - 4 ) - \frac{d}{d x} ( cos ( x ) - 4 ) tan ( x )}{( cos ( x ) - 4 ) ^{2}}

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

\frac{d}{d x} (cos (x) - 4) = - sin (x)

= \frac{sec ^{2} ( x ) ( cos ( x ) - 4 ) - ( - sin ( x ) ) tan ( x )}{( cos ( x ) - 4 ) ^{2}}

Vereinfache

= \frac{sec ^{2} ( x ) ( cos ( x ) - 4 ) + sin ( x ) tan ( x )}{( cos ( x ) - 4 ) ^{2}}
