(2 - x^{2})^{2} : 4 - 4 x^{2} + x^{4}

= \int 4 - 4 x^{2} + x^{4} d x

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int 4 d x - \int 4 x^{2} d x + \int x^{4} d x

\int 4 d x = 4 x

\int 4 x^{2} d x = \frac{4 x ^{3}}{3}

\int x^{4} d x = \frac{x ^{5}}{5}

= 4 x - \frac{4 x ^{3}}{3} + \frac{x ^{5}}{5}

Füge eine Konstante zur Lösung hinzu

= 4 x - \frac{4 x ^{3}}{3} + \frac{x ^{5}}{5} + C

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

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

\int \frac{x ^{3}}{( x ^{2} + 12 ) ^{3}} d x

\frac{d y}{d x} = \frac{1}{x ^{2} y ^{2}}
