Lösung

\frac{d}{d x} (\frac{x}{1 + 5 x ^{2}})

\frac{1}{( 1 + 5 x ^{2} ) 1 + 5 x ^{2}}

Schritte zur Lösung

\frac{d}{d x} (\frac{x}{1 + 5 x ^{2}})

Wende die Quotientenregel an:

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

= \frac{\frac{d x}{d x} 1 + 5 x ^{2} - \frac{d}{d x} ( 1 + 5 x ^{2} ) x}{( 1 + 5 x ^{2} ) ^{2}}

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

\frac{d}{d x} (1 + 5 x^{2}) = \frac{5 x}{1 + 5 x ^{2}}

= \frac{1 \cdot 1 + 5 x ^{2} - \frac{5 x}{1 + 5 x ^{2}} x}{( 1 + 5 x ^{2} ) ^{2}}

Vereinfache

\frac{1 \cdot 1 + 5 x ^{2} - \frac{5 x}{1 + 5 x ^{2}} x}{( 1 + 5 x ^{2} ) ^{2}} : \frac{1}{( 1 + 5 x ^{2} ) 1 + 5 x ^{2}}

= \frac{1}{( 1 + 5 x ^{2} ) 1 + 5 x ^{2}}

(t - 1)^{2} y^{^{'}} + 3 (t - 1) y = t + 2

x \to 0 lim (\frac{1 - ln ( x )}{e ^{\frac{1}{x}}})

\frac{d}{d x} (5 x^{5} - x^{3} + 3)

\frac{d}{d x} (e^{- 2 x + x^{2}})
