derivative of (x^3/({f)(x)})

Lösung

\frac{d}{d x} (\frac{x ^{3}}{f ( x )})

\frac{3 x ^{2} f ( x ) - \frac{d}{d x} ( f ( x ) ) x ^{3}}{f ( x ) ^{2}}

Schritte zur Lösung

\frac{d}{d x} (\frac{x ^{3}}{f ( x )})

Wende die Quotientenregel an:

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

= \frac{\frac{d}{d x} ( x ^{3} ) f ( x ) - \frac{d}{d x} ( f ( x ) ) x ^{3}}{f ( x ) ^{2}}

\frac{d}{d x} (x^{3}) = 3 x^{2}

= \frac{3 x ^{2} f ( x ) - \frac{d}{d x} ( f ( x ) ) x ^{3}}{f ( x ) ^{2}}

\int \frac{9}{t ^{2}} d t

\int sec (θ) (sec (θ) + tan (θ)) d θ

\int \frac{60}{2 x + 5} - 4 d x

\int_{1}^{8} x^{- \frac{2}{3}} d x

\int \frac{36 - x ^{2}}{x ^{2}} d x
