\frac{x ^{3}}{3 - x ^{2}}

\frac{9 x ^{2} - x ^{4}}{( 3 - x ^{2} ) ^{2}}

Schritte zur Lösung

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

Wende die Quotientenregel an:

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

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

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

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

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

Vereinfache

\frac{3 x ^{2} ( 3 - x ^{2} ) - ( - 2 x ) x ^{3}}{( 3 - x ^{2} ) ^{2}} : \frac{9 x ^{2} - x ^{4}}{( 3 - x ^{2} ) ^{2}}

= \frac{9 x ^{2} - x ^{4}}{( 3 - x ^{2} ) ^{2}}

\int_{- 9}^{0} \frac{1}{( x - 9 ) ^{2}} d x

\int e^{1 - 2 x} d x

\int e^{x} 17 + e^{x} d x

n = 1 \sum \infty tan (n)

x \to - 3 + lim (2 x^{2} + 4 x + 3)
