(4 - x^{2})^{2} : 16 - 8 x^{2} + x^{4}

= \int_{0}^{2} 16 - 8 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_{0}^{2} 16 d x - \int_{0}^{2} 8 x^{2} d x + \int_{0}^{2} x^{4} d x

\int_{0}^{2} 16 d x = 32

\int_{0}^{2} 8 x^{2} d x = \frac{64}{3}

\int_{0}^{2} x^{4} d x = \frac{32}{5}

= 32 - \frac{64}{3} + \frac{32}{5}

Vereinfache

32 - \frac{64}{3} + \frac{32}{5} : \frac{256}{15}

= \frac{256}{15}

(1 + x^{2}) \frac{d y}{d x} + 4 x y = (1 + x^{2})^{- 2}

x \to \infty lim (1 - \frac{4}{x})

\int \frac{5}{6 e ^{2 x}} d x

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